RIN 2127-AG40
Exemption From the Make Inoperative Prohibition
AGENCY: National Highway Traffic Safety Administration (NHTSA), DOT.
ACTION: Notice of proposed rulemaking.
SUMMARY: NHTSA is proposing a limited exemption from a statutory provision
prohibiting dealers, repair businesses and other specified commercial entities
from removing safety equipment or features installed on motor vehicles pursuant
to the Federal motor vehicle safety standards and from altering the equipment
or features so as to adversely affect their performance. Repair businesses and
dealers would be exempted from the prohibition to facilitate their modification
of motor vehicles so that persons with disabilities can drive or ride in them.
The exemption would permit modifications that have an unavoidable adverse
effect on safety equipment or features installed pursuant to some, but not all
requirements of the Federal safety standards. The requirements tentatively
selected for inclusion in the exemption were chosen after carefully balancing
their safety significance against the types of modifications needed for persons
with disabilities. By specifying which modifications may be made, the proposal
rule would provide universal, comprehensive guidance to all modifiers and would
thereby enhance the safety of vehicles modified to accommodate people with
disabilities.
DATES: Comments must be received by December 28, 1998.
ADDRESSES: Comments should refer to the docket number of this proposed rule and be submitted to: Docket Management, Room PL-401, 400 Seventh Street, SW, Washington, DC 20590 (Docket Room hours are 10:00 a.m.-5 p.m., Monday through Friday.)

I. Background and Overview
The U.S. Census Bureau estimates that nearly 49 million Americans, or 19.4
percent of the American population, have some type of physical, mental or other
disability.1 Their disabilities provide special
challenges for these people in obtaining and using various necessities of life.
One of those necessities is transportation.
Persons with disabilities often need their motor vehicles modified
to allow them to drive or ride in those vehicles. For example,
wheelchair lifts, power seats and hand controls are often installed to
enable paraplegics to enter and operate vehicles. The National Highway
Traffic Safety Administration (NHTSA) estimates that some 383,000
vehicles have some type of adaptive equipment installed in them to
accommodate a driver or passenger with a disability.2 The
agency believes the number of vehicles modified annually will increase
as a greater percentage of the population ages and as the Americans
With Disabilities Act (ADA) 3 improves access to employment,
travel, and recreation for people with disabilities.4
Modifying vehicles often involves removing equipment or features installed
pursuant to the Federal motor vehicle safety standards (standards) promulgated
by NHTSA or altering them so as to reduce their performance. 5 For
example, some individuals who have limited range of motion in their arms need
to replace the vehicle's original steering wheel with a reduced diameter
steering wheel so that they can operate the vehicle. Removing the original
steering wheel and air bag and replacing it with a smaller steering wheel that
lacks an air bag affects the vehicle's compliance with Standard No. 208,
Occupant Crash Protection, which requires the vehicle to be equipped with a
driver's side air bag.
Such removal or alteration violates a statutory provision which prohibits
certain parties from making such equipment and features inoperative. Section
30122 of Title 49 of the United States Codes provides that manufacturers,
distributors, dealers,6 and repair businesses 7 may not
knowingly make inoperative any part of a device or element of design installed
on or in a motor vehicle in compliance with an applicable standard. The agency
interprets "make inoperative" to mean any action that removes or disables
safety equipment or features installed to comply with an applicable standard,
or degrades the performance of such equipment or features.8
Violations of this provision are punishable by civil penalties of up to $1,100
per violation.
The statute authorizes NHTSA to issue regulations exempting a person from
the make inoperative prohibition and specifying which equipment and features
may be made inoperative. 49 U.S.C. 30122(c)(1). Such a regulation may be issued
for an individual or for a class of individuals.9 The legislative
history of the Act makes it clear that one of the intended purposes of the
exemption was to accommodate the need of individuals with disabilities for
vehicle modifications.10
To date, the agency has not issued a regulation exempting modifiers as a
class from the make inoperative provision for the purpose of modifying vehicles
to accommodate individuals with disabilities.11 Instead, the agency
considers requests from individual modifiers for permission to modify vehicles
for individuals with disabilities and responds on a request by request basis.
In some cases, the Chief Counsel of NHTSA has issued letters stating that the
agency will not institute enforcement proceedings against the motor vehicle
dealer or repair business for modifying a particular vehicle to accommodate a
person's disability. Such letters also caution that only necessary
modifications may be made and that the person making the modifications should
consider the safety consequences of the modifications. While this approach
eliminates the risk of civil penalties, it still leaves vehicle dealers and
repair businesses in technical violation of the make inoperative prohibition.
Further, it does not provide guidance to modifiers as to which
Federally-required safety equipment and features may be modified consistent
with the interests of motor vehicle safety. In addition, the agency is
concerned that the process is largely bypassed by most modifiers.
The agency believes that many modifiers modify vehicles without requesting
agency permission, and without receiving any agency guidance.12
Although approximately 383,000 vehicles have been modified to date
13 and there are an estimated 400 modifiers,14 the agency
has only received a total of approximately 250 requests 15 for
permission to modify a particular vehicle to accommodate a driver or passenger
with a disability. While NHTSA estimates that approximately 200 of the
modifiers receive some guidance on making vehicle modifications from industry
associations and others, the balance apparently receive no guidance at
all.16
The making of modifications without sufficient guidance raises concerns
about the ability of persons with disabilities to have their vehicles modified
in ways that do not unnecessarily or excessively affect the safety of their
vehicles. Modifiers tend to be small businesses with limited engineering and
other resources. Most do not have the resources to test whether a particular
modification would affect a vehicle's compliance with a particular
standard.17
The agency's experience with the vehicle modification industry indicates
that knowledge of the standards varies among the modifiers. While some
modifiers are very knowledgeable of the standards and the need to preserve a
vehicle's compliance with them, others are less knowledgeable. Many modifiers
do not possess sufficient knowledge of the standards to judge whether a
particular modification may affect a vehicle's compliance with the
standards.
To address these safety concerns, the agency has attempted to increase the
level of knowledge by participating in national industry conferences and
through other means.18 As a result, modifiers have increasingly
sought NHTSA's guidance with respect to the specific modifications they wish to
perform for individuals with disabilities. The agency has also amended several
of its standards to address particular needs of persons with
disabilities.19
However, NHTSA believes that a more comprehensive method is needed now to
address all of the standards and to reach the industry as a whole. The agency
believes that a regulation is needed to assist modifiers and members of the
disabled population in making appropriate decisions with respect to the
majority of vehicle modifications.20 To this end, the agency is
proposing an exemption from the make inoperative prohibition that will:
- Promote the mobility and safety of persons with disabilities by
providing comprehensive, universally available guidance;
- Improve the industry's ability to assess what modifications are
consistent with the statutory provision and the interests of safety;
- Improve the agency's ability to achieve its safety goals;
and
- Relieve modifiers of the burden of writing a letter to the agency for
each and every modification they wish to perform.
II. Proposed Exemption
A. Summary
NHTSA is proposing a limited exemption from the statutory provision
prohibiting motor vehicle dealers, repair businesses and other specified
commercial entities from removing or altering safety equipment or features
installed pursuant to the Federal motor vehicle safety standards so as to make
them inoperative. Repair businesses and dealers would be exempted from the make
inoperative prohibition for the purpose of modifying motor vehicles after the
first retail sale to accommodate a person with a disability. The exemption
would permit modifications affecting some, but not all, standards.
B. Specifics of the Proposed Exemption
While NHTSA believes that all individuals should, to the extent possible, be
provided with an equivalent level of vehicle safety, it also believes that all
Americans should, to the extent possible, be provided with an equivalent level
of mobility. Vehicles must often be modified to make them accessible to and
usable by people with disabilities. These modifications often make features
installed in compliance with the standards inoperative.
Among persons with disabilities, the type and severity of physical
impairments that affect a person's ability to access and use a vehicle vary
from person to person. Different impairments require different vehicle
modifications.21 Each different modification may affect a vehicle's
compliance with the standards in a different way. Consequently, due to the wide
range of disabilities and the various modifications needed to accommodate them,
it would be difficult for the agency to attempt to develop a regulation that
lists each type and level of severity of disability and that specifies the
particular set of standards that may be adversely affected by the modifications
suitable for each of those listed types and levels of severity of disability.
Instead, the agency has decided to issue the proposed
regulation, which would take a more general approach and provide modifiers with
the flexibility and guidance they need to accommodate various people with
disabilities while preserving the safety of the vehicle to the greatest extent
possible.
For a modification to be exempt from the make inoperative prohibition, a
dealer or repair business would have to meet certain conditions. The
modification would be permitted to affect compliance with the standards
specified, in whole or in part, below. However, the exemption would not grant
permission with respect to any other standards.22 Although it is not
expressly required, the agency expects that the dealer or motor vehicle repair
business would not modify the vehicle in a manner that adversely affects the
vehicle's compliance with those specified standards any more than is reasonably
necessary, considering cost and available technology, to accommodate the person
with the disability.
The standards and portions thereof proposed for exemption are
specified below:
- Standard No. 101, Controls and displays, S5.1 (a), which governs the
symbols and abbreviations used for certain controls; S5.3.1, which requires
illumination of certain controls when the head lights are on; S5.3.2 which
governs the color of telltales; or S5.3.5 which requires cabin lighting
forward of the driver's H point 23 to be able to be adjustable or
turned off. The purpose of Standard No. 101 is to limit driver distraction
from the driving task.
- S5.1.1.5 of Standard No. 108, Lamps, reflective devices, and
associated equipment, where the vehicle is modified to be driven without a
steering wheel and where it is not feasible to retain the original equipment
manufacturer (OEM) turn signal lever required by S5.1.1.5. The purpose of
Standard No. 108 is to ensure that roadways are illuminated, drivers can
signal their intentions, and vehicles are conspicuous.
- S4(a) of Standard No. 118, Power-operated window, partition, and roof
panel systems, where a remote ignition device is necessary. Standard No. 118
specifies requirements for the operation of power-operated windows,
partitions, and roof panels to help prevent injury or death from a window,
partition, or panel closing on a vehicle occupant (particularly
children).
- S5.3.1 of Standard No. 135, Passenger car brake systems, where the
foot control must be removed to accommodate a person's disability. Standard
No. 135 specifies requirements for service brake and associated parking brake
systems to ensure safe braking performance under normal and emergency driving
conditions.
- Standard No. 202, Head restraints, where (1) a vehicle modified for a
wheelchair seated driver or right front passenger and where no other seat is
supplied with the vehicle for the driver or right front passenger seating
position or (2) where the head restraint must be altered to accommodate a
driver's impairment. To reduce the frequency and severity of neck injuries in
rear-end and other collisions, Standard No. 202 requires all vehicles to be
equipped with a head restraint at each front outboard seating position that
meets specific size and performance requirements.
- S5.1 Standard No. 203, Impact protection for the driver from the
steering control system, where the modification requires a structural change
to, or removal of, the OEM steering shaft. The standard serves to reduce the
likelihood and severity of head, chest, neck, and facial injuries from impact
with the steering wheel.
- Standard No. 204, Steering control rearward displacement, where the
modification requires a structural change to, or removal of, the OEM steering
shaft. The standard serves to reduce the likelihood and severity of head,
chest, neck, and facial injuries due to vehicle components forcing the
steering shaft rearward toward the driver in a crash.
- Standard No. 207, Seating systems, where a vehicle is modified to be
driven by a person seated in a wheelchair and no other seat is supplied with
the vehicle for the driver; provided, that a wheelchair securement device is
installed at the driver's position. To minimize the likelihood that a seat
will collapse during a collision, Standard No. 207 establishes performance,
installation, and attachment requirements for seats.
- Standard No. 208, Occupant crash protection, provided that Type 2 or
2A seat belts meeting the requirements of Standard No. 209 and anchorages
meeting the requirements of Standard No. 210 are installed. The purpose of
Standard 208 is to reduce the number of vehicle occupant deaths and the
severity of vehicle occupant injuries incurred in a collision.
- S5 (the dynamic performance requirement only) of Standard No. 214,
Side impact protection, where the seat position must be changed to
accommodate a person's disability. Standard No. 214's requirements serve to
minimize the risk of serious and fatal injuries to vehicle occupants in side
impact collisions.
Under the proposed procedure, modifiers would no longer
have to seek the agency's approval before modifying a vehicle to accommodate a
person with a disability. The modifier could make the necessary modifications
as long as the modifications are needed to accommodate a person's disability
and only affect the vehicle's compliance with the specified standards. The
agency has not proposed to require modifiers to maintain
records of the vehicles they modify or notify the agency of such modifications.
Further, the agency has not proposed to require modifiers to
affix a label to the vehicle stating that the vehicle has been modified and may
no longer comply with all standards. A complete discussion of these issues and
requests for comments are contained in Sections III, IV and Section V of this
notice.
C. Scope of Proposed Exemption
The agency believes that compliance with certain standards is potentially
often affected by the manner in which vehicle modifications are currently made
for persons with disabilities. NHTSA has tried to identify those standards and
determine whether they are appropriate candidates for inclusion in the
proposed exemption.
In making this determination, the agency was mindful that its authority to
grant exemptions from the make inoperative exemption is limited, as noted
above, to those cases in which an exemption is consistent with safety. In light
of the legislative history indicating that one of the intended purposes of the
exemption was to accommodate persons with disabilities, NHTSA interprets this
limitation as requiring that an exemption not lead to any unnecessary reduction
in safety. A stricter reading of the limitation would defeat the goal of
allowing those modifications necessary to facilitate the mobility needs of
those persons. Although some modifications to a vehicle may result in a
decrease in safety to the vehicle's occupants, without such modifications,
persons with disabilities often cannot use their vehicles.
Accordingly, in developing this proposal, the agency has sought to
accommodate the mobility needs of people with disabilities, while preserving
safety to the extent possible. The agency is proposing to grant an exemption
from the make inoperative prohibition only with respect to those standards or
portions of standards requiring safety devices or features whose performance
would unavoidably have to be compromised to accommodate a person's
disability.
In determining whether to propose inclusion of modifications affecting
devices or features installed pursuant to a particular standard, NHTSA first
considered the range of specific disabilities that need to be accommodated to
enable people with disabilities to operate or ride in a vehicle. Second, the
agency considered what type of modifications would be necessary to accommodate
such disabilities. The following table includes illustrative examples of
disabilities and identifies the common vehicle modifications made to
accommodate those disabilities. These items are included here only as examples
and are, by no means, all inclusive.

Third, after considering the array of disabilities, NHTSA used its
engineering judgment to determine tentatively which safety devices or features
required by the standards might be affected by the variety of modifications
needed to accommodate individuals with those disabilities. For each standard
whose required device or feature might be affected by a vehicle modification,
the agency considered whether modifications to enable a person with
disabilities to operate or occupy a motor vehicle could be made reasonably
without violating the make inoperative prohibition. Many modifications can be
made without compromising a vehicle's compliance with the standards. If the
agency believed that compliance could be preserved easily or with a reasonable
amount of cost and effort, it did not include modifications involving that
standard in the proposed exemption.
The following cases illustrate how the agency determined whether a
particular modification should be exempt from the make inoperative
prohibition:
Case 1. A modifier may need to replace the original vehicle floor covering
with a material that is more conducive to the motion of a wheelchair's
wheels. With a minimum amount of effort, the original floor covering can be
replaced with a material that preserves the vehicle's certification to
Standard No. 302, Flammability of interior materials. Thus, NHTSA did not
propose to include Standard No. 302 in the proposed
exemption.
Case 2. A modifier may have to remove the driver's seat and install
wheelchair restraints to enable a quadriplegic to drive from a wheelchair.
Since Standard No. 207, Seating systems, requires that a driver's seat be
installed in the vehicle, removing the driver's seat would violate the make
inoperative prohibition. Since the only way the person could drive is from a
wheelchair, NHTSA tentatively determined that the modification was necessary
and that an exemption would, therefore, be appropriate.
Case 3. A modifier may have to lower the floor of the vehicle to
accommodate a person with a disability. Lowering the floor may require
relocating the vehicle's fuel tank which could affect the vehicle's
compliance with Standard No. 301, Fuel system integrity, which sets
performance requirements for fuel systems in crashes. The agency determined
that it is possible to make the modification without compromising compliance
with the standard. The agency determined that permitting a modifier to
compromise compliance with the standard was unacceptable since it could
unnecessarily expose occupants to an increased risk of fire.
Following is a discussion of the standards the agency believes are
appropriate candidates for the exemption and those it believes are
inappropriate. The discussion addresses only those standards the agency
believes might be affected by common vehicle modifications. The following
standards will not be discussed and are not recommended for exemption because
the agency believes there are no common vehicle modifications that should
affect the vehicles, vehicle systems, or equipment to which they apply:

- Standards for Which Permission Would Be Granted To Make Safety Features Inoperative
- Standard No. 101, Controls and displays. The purpose of Standard 101
is to limit driver distraction from the driving task. The standard does not
require or prescribe exact locations or methods of operation for any control
or display. The standard does, however, require that if certain controls are
provided, they "shall be operable by the driver" and that if certain displays
are furnished, they "shall be visible to the driver." The standard also
directs that the driver be restrained for testing and lists which controls
must be illuminated when the vehicle's headlights are on.
Controls and
displays, as well as the driver's seating position, are often moved when a
vehicle is modified. These changes create the potential to take the vehicle
out of compliance with 49 CFR 571.101 in three ways. First, controls or
displays may be moved to a position that is not visible to the driver when
the driver is looking forward (e.g. switches may be moved to a door mounted
touch panel to be operated by the driver's elbow, or switches may be mounted
in a head rest). Second, a change in the driver's seating position may result
in the driver's inability to see or reach an OEM control or display. Finally,
changing the restraint system can make it impossible to comply with section 6
of the standard which requires the driver to be restrained pursuant to the
requirements of Standard No. 208, Occupant Crash Protection. The agency
believes that such changes do not create a safety problem since the purpose
of the modification is to make as many functions as possible operable by the
disabled driver.
NHTSA is aware that other drivers may occasionally use
the modified vehicle; however, the agency does not believe this presents a
serious problem. The vehicle is primarily designed for the disabled person
and that individual will be accustomed to the availability and placement of
controls and displays in his or her vehicle. The controls can still be placed
in a way that minimizes any potential distraction for the driver with a
disability. NHTSA believes that most of the vehicles will be driven by
someone other than the disabled driver only infrequently. For these reasons,
NHTSA believes a limited exemption from the make inoperative exemption for
Standard No. 101 is appropriate. NHTSA does not believe that an exemption
would be appropriate from S5.1(a), which governs the symbols and
abbreviations used for certain controls; S5.3.1, which requires illumination
of certain controls when the head lights are on; S5.3.2 which governs the
color of telltales; or S5.3.5 which requires cabin lighting forward of the
driver's H point 24 to be able to be adjustable or turned
off.
- Standard No. 108, Lamps, reflective devices, and associated
equipment. The purpose of Standard No. 108 is to ensure that roadways are
illuminated, drivers can signal their intentions, and vehicles are
conspicuous. NHTSA is aware of only two situations in which common vehicle
modifications could take the vehicle out of compliance with 49 CFR Sec.
571.108. NHTSA believes the make inoperative exemption is necessary for only
one of the modifications; the other modification can be performed in a way
that preserves the vehicle's compliance with the standard.
The agency
believes that vehicles that are modified so that they no longer have a
steering wheel cannot conform to S5.1.1.5, which requires turn signals to be
self-canceling by the steering wheel rotation. Although NHTSA believes that
such cases are rare, the agency believes that such a modification cannot be
made without taking the vehicle out of compliance with Standard No. 108.
Other modifications to the self- canceling feature of the turn signal are
made without removing the steering wheel. For example, touch pads that
control the vehicle's turn signals can be installed without removing the
steering wheel. Some touch pad actuated turn signals are canceled by a timer,
not the steering wheel rotation. In all cases known to NHTSA where a touch
pad is installed to control the vehicle's turn signals and the steering wheel
is not removed, the OEM turn signal lever and canceling feature is retained
on the vehicle. Since the OEM turn signal lever and canceling feature is
retained on the vehicle, the modification would not compromise the compliance
of the OEM equipment provided to meet S5.1.1.5.
The standard requires the
installation of a center high-mounted stop lamp (CHMSL) and specifies its
location. 49 CFR Secs. 571.108, S5.1.1.27, S5.3.1.8(a). Certain vans which
require the installation of a raised roof to accommodate a wheelchair seated
occupant will require the CHMSL to be moved. NHTSA believes that the CHMSL
can be reinstalled in a way that preserves the vehicle's compliance with
Standard No. 108. NHTSA is unaware of any situations in which this cannot be
done. For example, sometimes in a van conversion rear doors must be
lengthened when a raised roof is installed. If the van originally had one
CHMSL above the doors, the lengthened doors could be retrofitted with two
CHMSLs pursuant to S5.1.1.27(b) of the standard.25
NHTSA
believes a make inoperative exemption from S5.1.1.5 of Standard No. 108 is
appropriate only where a vehicle is modified to be driven without a steering
wheel and where it is not feasible to retain the OEM turn signal lever. NHTSA
seeks comment on whether there are cases in which the OEM turn signal
actuating device and function is not retained for the use of drivers other
than the driver for whom the vehicle was modified. If such cases exist, do
the substitute turn signal controls installed for the driver with a
disability have the self-canceling feature required by Standard No. 108
S5.1.1.5? Do they have some self-canceling feature other than steering wheel
rotation?
- Standard No. 118, Power-operated window, partition, and roof panel
systems. Standard No. 118 specifies requirements for the operation of
power-operated windows, partitions, and roof panels to help prevent injury or
death from a window, partition, or panel closing on a vehicle occupant
(particularly children). NHTSA knows of only one situation where a
modification would take the vehicle out of compliance with Standard No. 118.
Disabled persons who have trouble maintaining a constant body temperature
(e.g. quadraplegics and burn victims) and live in very cold or very hot
climates use a remote control ignition device so that the occupant
compartment can be warmed or cooled before they enter. Section 4(a) of the
standard requires that before a power operated window, partition, or roof
panel system can be closed, the key that activates the vehicle's engine must
be in the " `ON', `START', or `ACCESSORY' position." In the modified vehicle
under discussion here, the vehicle is running when the person enters, hence
the person has control of the power operated windows even though there is no
key in the ignition. Thus, NHTSA believes make inoperative exemption from
S4(a) of Standard No. 118 is appropriate where a remote ignition device is
necessary to accommodate a disability.
- Standard No. 135, Passenger car brake systems. Standard No. 135
specifies requirements for service brake and associated parking brake systems
to ensure safe braking performance under normal and emergency driving
conditions.26 The addition of some sort of hand control to the OEM
system--usually a system that attaches in some manner to the brake pedal--is
the most common modification made to any brake system for a driver with a
disability. Normally these systems maintain the OEM brake control. Also
common are modifications made to the level of effort (pressure) required of
the driver to operate the brake. Such modifications are known as low-effort
and zero-effort braking and increase the amount of power assist to the
driver. Low- effort and zero-effort braking is accomplished by reworking the
OEM power brake system. Most of these modifications preserve the OEM foot
pedal and affect only the method of actuation of the braking system. The
agency believes that some, relatively uncommon, modifications may require
removal of the OEM foot pedal. For example, a disabled person who experiences
involuntary muscle spasms in his legs may have to have the OEM foot control
removed to prevent him from inadvertently activating the vehicle's brake
during a spasm. S5.3.1 of Standard No. 135 specifies that the service brakes
be activated by a foot control. Consequently, NHTSA has tentatively concluded
that exemption from S5.3.1 of Standard No. 135 may be appropriate in those
situations where the foot pedal must be removed to accommodate a person's
disability. NHTSA seeks comment on whether its tentative conclusion is
correct. Are there disabilities which require removal of the OEM foot pedal?
The agency also seeks comment from the vehicle manufacturers, hand control
manufacturers, vehicle modifiers, those who adapt power brake systems, and
users, as to whether there are brake modifications that incapacitate the OEM
brake controls and would affect the vehicle's performance in any of the
required tests. Specifically, does any joy stick driving control prevent the
use of the OEM brake pedal or affect the vehicle's potential to perform the
braking tests? Does increasing the power assist to the brakes affect the
vehicle's potential to perform the braking test? The agency also seeks
comment as to whether there are modifications made to the accelerator control
that do not preserve the OEM performance and function.
- Standard No. 202, Head restraints. To reduce the frequency and
severity of neck injuries in rear-end and other collisions, Standard No. 202
requires each front outboard seating position in all vehicles to be equipped
with a head restraint that meets specific size and performance requirements.
Vehicles may be modified to accommodate a wheelchair seated driver or right
front seat passenger. Such a modification requires the removal of the OEM
seat and, as a consequence, the head restraint. NHTSA is aware that some
wheelchairs are equipped with head rests or positioning devices and that some
vehicles modified to be driven by wheelchair seated drivers are equipped with
swing-away head rests. Although the agency does not know for certain, it
doubts that the head rests installed on some wheelchairs or the swing away
head rests attached to vehicles comply with Standard No. 202. Thus, NHTSA
believes that compliance with Standard No. 202 may be compromised when the
OEM seat is permanently removed to accommodate a wheelchair-seated occupant
at either of the front outboard seating positions.
In addition to the
case of a wheelchair seated occupant, NHTSA knows of another modification
that could make Standard No. 202 inoperative. Some drivers (such as a driver
with poor peripheral vision) may need to alter the size of their vehicle's
head restraint so it no longer interferes with their ability to see rearward
over their shoulders.27 Reducing the size of the head restraint
could affect the vehicle's compliance with Standard No. 202 in a variety of
ways. If the head restraint is altered so that the remaining height of the
head restraint is less than 27.5 inches above the seating reference point,
the remaining width is less than 10 inches on a bench seat, or the remaining
width is less than 6.75 inches on an individual seat,28 the
vehicle may no longer comply with the requirements of Standard No. 202. Even
smaller reductions in the size of a head restraint affect the head
restraint's ability to meet the performance requirements of S4.3 of Standard
No. 202.
In light of the above, NHTSA believes an exemption from the make
inoperative prohibition with regard to Standard No. 202 is warranted in two
situations only. First, where the OEM seat is permanently removed so that
only a wheelchair seated driver or right front passenger can occupy either or
both front outboard seating positions. If the vehicle is modified to have a
detachable driver or right front passenger seat, the detachable seat must
comply with Standard No. 202.29 If an OEM driver or passenger seat
is supplied with the vehicle, that seat must comply with Standard No. 202.
Second, an exemption would be warranted if the head restraint must be altered
to accommodate a driver's disability. NHTSA solicits comment on whether the
head rests used on some wheelchairs would meet Standard No. 202's
requirements.
- Standard No. 203, Impact protection for the driver from the steering
control system and Standard No. 204, Steering control rearward displacement.
Standard No. 203 and Standard No. 204 serve to reduce the likelihood and
severity of head, chest, neck, and facial injuries due to contact with the
steering wheel. Standard No. 203 requires (1) that the impact force developed
on a chest body block impacting the steering wheel at 15 mph be less than
2,500 pounds in a three millisecond interval,30 and (2) that no
steering control system components catch the driver's clothing or jewelry.
The standard does not apply to vehicles that conform to S5.1, Standard No.
208 (i.e., air bag requirements). Standard No. 204 requires that the upper
end of the steering column 31 be displaced less than five inches
when the vehicle impacts a fixed full frontal barrier at 30 mph.
These
two standards assume that the vehicle uses the type of steering system
typically installed in a vehicle: the steering column longitudinal axis
points toward the driver and a steering wheel, mounted at the end of the
column, is used by the driver to steer the vehicle. Vehicles modified to be
driven by persons with disabilities do not always have such steering systems.
Some individuals with disabilities require alternative steering systems such
as joystick steering (usually mounted to one side of the driver), horizontal
steering (the column points toward the driver, but the face plane of the
steering wheel is parallel to the column), foot steering, or the Scott
steering system to accommodate their particular disability.32 In
addition, extensions are sometimes added to the OEM steering shaft to allow a
wheelchair seated driver to sit further back in the vehicle than the OEM
shaft will allow (usually because his or her wheelchair will not fit into the
area reachable by the OEM system).
The agency would like to point out the
difference between the steering "shaft" and the steering "column". While the
words "steering column" are often used in everyday conversation when
referring to the system consisting of the steering shaft, covered by the
steering column, S3 of Standard 204 specifically defines the steering shaft
as "a component that transmits steering torque from the steering wheel to the
steering gear," while the steering column is "a structural housing that
surrounds a steering shaft." It is the agency's intent to discriminate
between fairly minor modifications that may involve attaching equipment to
the steering column, or cutting away a portion of that housing, from more
serious modifications that require a change to the component that connects
the driver control to the steering gear, because it is the steering shaft
that is most likely to transmit crash loads from the engine compartment of
the vehicle to the driver. Therefore, NHTSA believes that a person modifying
a vehicle for a person with disabilities should preserve the vehicle's
certification with respect to the requirements of Standard Nos. 203 and 204
except when a modification requires a structural change to, or removal of,
the original steering shaft. NHTSA does not believe that the simple addition
of a piece of adaptive equipment (AE), such as a hand control, to the
steering column constitutes a change to the steering shaft. The agency
requests comment on whether the following modifications can be performed in a
manner that preserves the vehicle's compliance with Standard No. 204's
steering column displacement requirements: (1) the extension of the steering
shaft, (2) the installation of horizontal steering, or (3) the installation
of mechanical hand controls. The agency also seeks comment on whether there
are modifications which require changes to the steering column, without a
change to the steering shaft, and which can only be made in a way that would
affect the vehicle's compliance with S5.1 of Standard No. 203 or with
Standard No. 204.
- Standard No. 207, Seating systems. To minimize the likelihood that a
seat will collapse during a collision, Standard No. 207, Seating systems
establishes performance, installation, and attachment requirements for seats.
The standard requires vehicles to be equipped with a driver's seat and
requires all seats installed in a vehicle to both withstand and remain in
their adjusted position when certain loads are applied in various directions
to the seats. The standard also requires folding seats to be equipped with a
restraining device and a release mechanism. NHTSA knows of only one vehicle
modification in which certification to Standard No. 207 cannot be
maintained--the permanent removal of the driver's seat so that the vehicle
can be driven by a driver seated in a wheelchair. In most instances when the
driver for whom the vehicle is modified is sitting in a wheelchair, an
additional driver's seat and a means for attaching the seat to the vehicle
floor are provided. This seat and the attachment mechanism should conform to
the requirements of Standard No. 207; NHTSA knows of no reason why it
cannot.
NHTSA believes that only a limited exemption from Standard No.
207 is appropriate. Wheelchairs and other non-automotive seats are not
designed to withstand loads and remain in position during a collision. NHTSA
believes that only vehicles modified to be driven by a person seated in a
wheelchair and that are equipped with a wheelchair securement device should
be exempt from compliance with Standard No. 207. The exemption would not
apply to any vehicle equipped with a detachable driver's seat; in that case,
the detachable seat would have to comply with the standard's
requirements.
The agency is aware that some commenters may argue that the
installation of a six-way power seat base (allowing a wheelchair user to
transfer to the OEM driver's seat) requires exemption from Standard No. 207.
NHTSA disagrees. The agency believes that it is reasonable and practicable to
attach these seat bases to a vehicle in a manner that would not compromise a
vehicle's compliance with Standard No. 207. Thus, NHTSA believes that an
exemption from the make inoperative prohibition for the installation of a
power seat base is inappropriate.
- Standard No. 208, Occupant crash protection. The purpose of Standard
No. 208 is to reduce the number of vehicle occupant deaths and the severity
of vehicle occupant injuries in a crash. The standard requires vehicles to be
equipped with specific manual and automatic restraint systems (e.g. seat
belts and air bags) and to meet specified injury criteria during a crash
test.33 Many vehicle modifications could affect a vehicle's
compliance with this standard. The agency has tried to determine how various
modifications might affect a vehicle's compliance with the standard. NHTSA
knows that some types of modifications unavoidably affect a vehicle's
compliance with Standard No. 208. For example, any modification that requires
the removal of the OEM steering wheel, and hence the driver air bag, affects
the vehicle's compliance with Standard No. 208. In addition, any modification
to the seat which requires removing an air bag sensor located under the seat
compromises a vehicle's compliance with the standard. Based on the results of
testing, NHTSA knows of other modifications that will not affect a vehicle's
compliance with the standard. For example, the results of a crash test
conducted at the University of Virginia indicate that raising the body off
the frame or lowering the floor of a full size van will not compromise a
vehicle's compliance with Standard No. 208, at least for a driver seated in a
modified OEM seat.34 In addition, NHTSA believes that the simple
attachment of a steering control device on the OEM steering wheel will not
affect a vehicle's compliance with Standard No. 208.35
The
agency is also aware that there are some modifications which may take a
vehicle out of compliance with Standard No. 208. For example, nearly every
modification to the occupant compartment forward of the B pillar could
compromise a vehicle's compliance with Standard No. 208. At this point in
time, the agency lacks the data or test results needed to determine whether
some modifications affect a vehicle's compliance with Standard No.
208.36 For example, the agency does not know if cutting the knee
bolster to accommodate the push rods in a standard set of mechanical hand
controls affects the vehicle's ability to meet the injury criteria in a
crash. The agency is also uncertain whether cutting the vehicle floor to
install a power pan in the driver's area or whether cutting the roof
adversely affects the vehicle's structural response in a crash to the point
that Standard No. 208's criteria can no longer be met. Finally, NHTSA does
not know whether removing pretensioners during a modification of the belt
system makes it impossible to meet the criteria of Standard No. 208.
In
light of the standard's complexity and the uncertainty concerning the effect
of some modifications on a vehicle's compliance with Standard No. 208, NHTSA
believes that exemption from the make inoperative prohibition for Standard
No. 208 should be granted for any modification necessary to accommodate a
disability, provided the modifier installs Type 2 37 or Type 2A
38 belts that comply with Standard No. 209, and provided the belt
anchorages comply with Standard No. 210. The agency notes, however, that the
exemption would not apply in any situation where compliance with the standard
could be preserved and a person's disability could be accommodated by the
installation of an air bag on-off switch. NHTSA seeks comment from drop floor
minivan alterers on whether they have been able to certify their vehicles to
Standard No. 208 since September 1, 1997 (the date the section 4.2 exclusion
expired). The agency also seeks comment from hand control manufacturers as to
whether they believe OEM components installed to meet Standard No. 208 (e.g.
knee bolsters) are made inoperable by the installation of their controls. The
agency seeks comments from modifiers on how, how often, and why they must
disable seat pretensioners.
- Standard No. 214, Side impact protection. Standard No. 214's
requirements serve to minimize the risk of serious and fatal injuries to
vehicle occupants in side impact collisions. The standard specifies injury
criteria to be measured during a crash test and sets strength requirements
for doors. With respect to the dynamic performance requirement of Standard
No. 214, NHTSA believes that an exemption from the make inoperative
prohibition is warranted for cases in which the seat position must be changed
to accommodate a person's disability. The agency discovered during the course
of the development of the test procedure for the side impact crash test that
data indicating injury to the dummy will be affected by seat height, fore/aft
position, and the distance between the dummy and the door interior surface.
(The use of occupant restraints, however, did not affect the test results
significantly.) The agency requests comments on whether OEMs or modifiers
believe there are modifications, other than those that change the seat
position, that would affect the vehicle's compliance with S5 of Standard No.
214. NHTSA does not believe there are any modifications which would
necessarily reduce door strength to an extent that the strength requirement
of Standard No. 214 could not be met. Thus, NHTSA does not believe a make
inoperative exemption is warranted for that portion of the standard. NHTSA
requests comment on whether OEMs or modifiers believe there are modifications
which must be done in a manner that necessarily compromises door
strength.
- Standards for Which Permission Would Not Be Granted To Make Safety Features Inoperative
- Standard No. 102, Transmission shift lever sequence, starter
interlock, and transmission braking effect. Standard No. 102 requires
automatic transmissions to have: (1) a specified transmission shift lever
sequence, (2) a starter interlock, and (3) at least one forward drive
transmission position that provides a greater degree of engine braking than
the highest speed transmission ratio (i.e. one low gear). To accommodate
certain disabilities, some modifications are made to the method by which the
vehicle is started and the transmission gear is selected. A common
modification is the attachment of an extension lever to the column-mounted
gear selection lever in a passenger car to permit left-handed gear selection.
NHTSA is unaware of any modification which would need to change the
transmission gear selection sequence, disable the starter interlock, or
disable the lower forward drive gear ratios so there is no longer a low gear.
Thus, NHTSA does not believe a make inoperative exemption for Standard No.
102 is appropriate. NHTSA solicits comment on whether modifications to the
method by which the vehicle is started and the transmission gear is selected
are necessary to accommodate a person with a disability.
- Standard No. 103, Windshield defrosting and defogging systems, and
Standard No. 104, Windshield wiping and washing systems. Standard No. 103 and
Standard No. 104 specify requirements for the area of the windshield that
must be cleared by the defrosting and defogging and windshield wiping and
washing systems, respectively. Vehicle modifications commonly result in the
relocation of switches and a reduction in the features normally available to
the driver while the vehicle is in motion. For example, if the OEM provides
three or four wiper speeds on a dial control, a disabled driver who needs a
touch pad or other switch panel may have access to only two speeds. However,
neither this situation nor any other modification to these systems that NHTSA
knows of are violations of the make inoperative prohibition since the minimum
requirements of the standard are met. The agency is unaware of any reason why
a modification would affect the performance level of these systems to the
extent that the vehicle no longer complied with these standards. NHTSA,
therefore, does not believe an exemption for Standard No. 103 or Standard No.
104 is appropriate.
- Braking Standards. Standard No. 105, Hydraulic brake systems and
Standard No. 121, Air brake systems govern the performance of various braking
systems in different types of vehicles. Standard No. 105 applies to
multipurpose passenger vehicles (MPVs), trucks, buses and passenger cars
(manufactured before September 1, 2000) with hydraulic brake systems.
Standard No. 121 applies to trucks, buses and trailers equipped with air
brake systems. Manufacturers of passenger cars may elect to comply with
Standard No. 135 instead of Standard No. 105 until August 31,
2000.39 All of these standards help ensure safe vehicle braking
performance in normal and emergency driving situations.
The most common
modification to any brake system when adapting a vehicle to be driven by a
person with a disability is the addition of some sort of hand control to the
OEM system--usually a system that attaches in some manner to the brake pedal.
Normally these systems maintain the OEM brake control. Also common are
modifications to the level of effort (pressure) required of the driver to
operate the brake. These modifications are called low-effort and zero-effort
braking and increase the amount of power assist to the driver. This is
accomplished by reworking the OEM power brake system. Since these
modifications are only to the method of actuation and in most cases preserve
the OEM foot pedals, NHTSA does not believe that these modifications take a
vehicle out of compliance with any part of these braking standards. Unlike
Standard No. 135, Standard Nos. 105 and 121 do not specify that the service
brakes be activated by a foot control. Therefore, NHTSA does not believe that
make inoperative exemption for Standard Nos. 105 and 121 is warranted. The
agency seeks comment from the vehicle manufacturers, hand control
manufacturers, vehicle modifiers, those who adapt power brake systems, and
users, as to whether there are brake modifications that incapacitate the OEM
brake controls and would affect the vehicle's performance in any of the
required tests. Specifically, does any joy stick driving control prevent the
use of the OEM brake pedal or affect the vehicle's potential to perform the
braking tests? Does increasing the power assist to the brakes affect the
vehicle's potential to perform the braking test? The agency also seeks
comment as to whether there are modifications made to the accelerator control
that do not preserve the OEM performance and function.
- Standard No. 111, Rearview mirrors. To ensure that drivers have a
clear and unobstructed view to the rear of the vehicle, the standard
specifies the location, field of view, magnification and labeling of rearview
mirrors on all vehicles. While mirrors are relocated, extra mirrors added, or
larger mirrors substituted for the OEM when vehicles are modified for persons
with disabilities, NHTSA does not believe these modifications should affect
the vehicles' certification to Standard No. 111. Since there should be no
situation in which non- compliance with the standard is necessary or advised,
NHTSA is not proposing a make inoperative exemption from Standard No.
111.
- Standard No. 113, Hood latch systems. Standard No. 113 requires that
cars, MPVs, trucks and buses have a second latch position on the hood latch
system to prevent the hood from unlatching, opening and blocking a driver's
view through the windshield. NHTSA is not aware of any modifications that are
made to hood latch systems when a vehicle is modified to accommodate a person
with a disability. NHTSA is aware that a modification to the method of
unlatching might be necessary to allow a person with reduced range of motion
or strength, or seated in a wheelchair to open the hood. NHTSA does not
believe, however, that a modification to the method of unlatching would
require the elimination of the second latch position; thus, the agency does
not believe a make inoperative exemption for Standard No. 113 is warranted.
The agency seeks comment on whether there are modifications that would
require eliminating the second latch position.
- Standard No. 124, Accelerator control systems. Accelerator control
systems is intended to help prevent runaway acceleration of vehicles. The
standard requires a vehicle's throttle to return to its idle position when
the driver withdraws all force from the accelerator control or when there is
a disconnection in the accelerator system between the control and the engine.
The vehicle modification situation with respect to Standard No. 124 is
directly analogous to the previous discussion of the braking standards. Most
modifications to the accelerator system involve the addition of hand operated
controls to the OEM system. NHTSA does not believe, therefore, that the
vehicle is taken out of compliance with the standard as long as the OEM
performance and function are preserved. Thus, NHTSA does not believe an
exemption for Standard No. 124 is justified. The agency seeks comment from
the vehicle manufacturers, hand control manufacturers, vehicle modifiers,
those who adapt acceleration systems, and users, as to whether there are
accelerator modifications that incapacitate the OEM accelerator controls and
would affect the vehicle's performance in any of the required tests. Are
there modifications made to the accelerator control that do not preserve the
OEM performance and function?
- Standard No. 201, Occupant protection in interior impact. The purpose
of this standard is to protect vehicle occupants from serious injury from
impacts with interior components in a collision. The certification of a
vehicle to the current standard would most likely be affected, if at all,
through the installation of adaptive equipment (AE) for secondary controls.
Special switches or touch pads are often installed to allow a person to reach
and operate the controls for power windows, washer/wipers, and headlights.
These controls can be mounted almost anywhere: on the side door panel, the
arm rest, the front instrument panel, or the windshield header. It does not
appear that these controls are large, heavy or rigid enough to cause
significant injury upon occupant impact, although they may inflict
lacerations. NHTSA seeks comments from OEMs and modifiers on whether or not
the addition of adaptive equipment and devices, such as hand controls or
knobs, affect the results of tests required by 49 CFR 571.201, S5.1,
"Instrument Panels"?
NHTSA believes, however, that there may be a problem
with van conversions for wheelchair-seated drivers when the new requirements
for impact testing to the upper interior components become effective. The
extra padding needed on the windshield header to comply with the new
requirements may interfere with a driver's line of sight, since a
wheelchair-seated driver sits higher above the vehicle floor than a driver
using an OEM seat. NHTSA believes this could be accommodated by lowering the
floor in the driver area; the agency is aware that this will not be a
solution for everyone. Those drivers who are very tall, or for whom the floor
cannot be lowered enough, may need to have sections of padding on the header
removed. Also, it may be much safer to remove padding from the header than to
lower the floor of the vehicle further than would be necessary if the header
were not padded. NHTSA seeks comments from OEMs on how they expect upper
interior components to change under the new requirements. Specifically, if
the eye ellipse of a wheelchair-seated driver is higher than that of a 95th
percentile male, will increased padding or other design changes affect that
driver's line of sight?
- Standard No. 206, Door locks and door retention components. To
minimize the likelihood that vehicle occupants will be ejected from a vehicle
during a crash, Standard No. 206, Door locks and door retention components,
requires hinged doors to have latches with two positions: fully latched and
secondarily latched. The latch and striker must not separate under certain
longitudinal, transverse, and inertial load and the door hinges must not
separate under certain longitudinal and transverse loads. The standard also
specifies that track and slide combinations on sliding doors must not
separate under a 4,000 pound transverse load. The standard also requires
vehicles to have door locks operable from the interior of the vehicle.
Standard No. 206 excludes "* * * side doors which are equipped with
wheelchair lifts and which are linked to an alarm system." The agency has
granted a petition asking to expand this exclusion to side doors fitted with
ramps.40 This action by the agency does not mean that the action
desired by the petitioner will be taken, only that NHTSA will examine the
issue.
Several vehicle modifications have the potential to affect door
closures and the doors' ability to remain closed during impact. Examples
include electrically operated door openers for both hinged and sliding doors
and lengthened doors that are sometimes installed when the vehicle roof is
raised. Standard 206 is crucial in preventing the ejection of occupants in a
crash. NHTSA has no compelling evidence that the OEM door latching mechanism
cannot be preserved, or its equivalent installed, in the course of door
modifications. Therefore, NHTSA does not believe exemption from the make
inoperative prohibition for Standard No. 206 is justified. The agency also
solicits comment on whether door latching and locking mechanisms must be
disabled or changed in the course of vehicle modifications in a manner that
takes them out of compliance with Standard No. 206, Door locks and door
retention components.
- Standard No. 209, Seat belt assemblies. This standard sets out
requirements for seat belt assemblies as items of motor vehicle equipment.
NHTSA is not proposing exemption from the make inoperative prohibition since
the agency sees no reason why modifiers cannot use Standard No. 209-compliant
systems.
- Standard No. 210, Seat belt assembly anchorages. Standard No. 210 is
a vehicle standard that establishes strength and location requirements for
seat belt assembly anchorages. The requirements ensure that the belt loads
during a crash are transferred to the skeleton of the occupant and not to the
occupant's soft tissue. The standard also ensures that the restraint
anchorages are strong enough to withstand the force of a crash. Compliance
with the criteria is fairly simple to measure. Traditionally, NHTSA has said
that a vehicle may comply with Standard No. 210 as manufactured or as
modified. The agency does not believe, therefore, that exemption from make
inoperative with respect to Standard No. 210 is necessary. If belt anchorages
are moved, or otherwise modified, to accommodate a person with a disability,
NHTSA believes measurements, calculations, or engineering judgment can be
used to ensure that Standard No. 210 is met in the new position.
- Standard No. 216, Roof crush resistance. The purpose of Standard No.
216 is to reduce the number of deaths and injuries caused by a roof crushing
into the vehicle during a rollover. The standard establishes static strength
requirements for both car and LTV roofs. A common modification that could
compromise a vehicle's certification to this standard is the installation of
a raised roof (most often made of fiberglass). The agency believes that
modifiers almost always, if not exclusively, achieve this roof modification
by purchasing a replacement roof from a roof manufacturer and installing the
new roof according to the roof manufacturer's instructions. NHTSA believes
that the roof manufacturer should be able to provide guidance to the vehicle
modifier on the strength of the roof and the vehicle make/models for which
installation of that roof is appropriate. The agency does not believe that it
is necessary for a raised roof to be installed in a manner that takes a
vehicle out of compliance with Standard No. 216. NHTSA invites roof
manufacturers and vehicle modifiers to comment on whether there are raised
roofs which must be installed in a way that adversely affects the vehicle's
compliance with Standard No. 216, Roof crush resistance, or if there are
instances in which a raised roof is achieved by some method other than
installing a replacement roof.
- Standard No. 301, Fuel system integrity and Standard No. 303, Fuel
system integrity of compressed natural gas vehicles. To reduce deaths and
injuries occurring from fires caused by leaking fuel during and after a
crash, Standard No. 301, Fuel system integrity and Standard No. 303, Fuel
system integrity of compressed natural gas vehicles set performance
requirements for fuel systems in crashes. Preserving fuel system integrity in
a crash to prevent occupant exposure to fire is extremely important to all
persons, but perhaps even more so for persons with disabilities since they
often require more time to exit a vehicle.
Vehicle certification to
Standard No. 301 can be compromised when the fuel tank, supply lines, and
filler neck are moved in the process of lowering the floor of a van or
minivan. NHTSA believes it is essential for safety that anyone working on a
motor vehicle place a tank in such a way that it is not subject to impact by
the sharp edges of the vehicle's structures, that fuel lines are not routed
near hot surfaces, and that the fuel filler neck is not installed in such a
way that it will separate from the tank, or be sheared off in a collision. In
addition, NHTSA is aware of one tank manufacturer who has demonstrated that
when its tank was correctly installed in the rear of a 1992 Ford E150 with a
lowered floor and raised body, the vehicle met the performance requirements
of Standard No. 301. The points discussed under Standard No. 301 are
applicable to Standard No. 303, Fuel system integrity of compressed natural
gas vehicles. NHTSA, therefore, believes strongly that a make inoperative
exemption for Standard No. 301 and Standard No. 303 is not
justified.
- Standard No. 302, Flammability of interior materials. To reduce the
occurrence of deaths and injuries to vehicle occupants from fire, especially
those which originate in the vehicle's interior, Standard 302, Flammability
of interior materials specifies that any material within one-half inch of the
occupant compartment air space shall not "burn, nor transmit a flame front
across its surface, at a rate of more than four inches per minute." Materials
meeting this standard are readily available and the test procedure described
in the standard is fairly simple.
There are many modifications which have
the potential to compromise a vehicle's certification to Standard No. 302.
One example is the replacement of OEM carpet in vans with a surface which is
easier for wheelchairs to roll on. Carpet may also be replaced in the process
of lowering a floor. Some vehicle modifiers have told NHTSA staff that they
do not use OEM materials when making changes because these materials are much
more expensive than others more commonly available.
The agency believes
that fire safety for persons with disabilities should not be compromised
during vehicle modification. Even if OEM materials are not used, modifiers
can employ substitutes that comply with Standard No. 302. NHTSA believes it
is the duty of the vehicle modifier to get information from its suppliers on
the fire resistance of the materials it uses. Suppliers should be able to
tell modifiers whether the material will meet Standard No. 302 requirements.
The agency is not proposing a make inoperative exemption for Standard No.
302.
III. Explanation of Procedural Differences Between Proposed Exemption and Existing Exemption re Air Bag On-Off Switches
In developing the procedures for implementing the proposed
exemption, the agency considered the detailed eligibility procedures it adopted
as part of the make inoperative exemption that it issued in November 1997 to
permit the retrofit installation of on-off switches for air bags. Generally,
the agency tentatively concluded that the circumstances warranting the detailed
procedures in that rulemaking are not present in this rulemaking.
The agency included detailed paperwork and agency authorization procedures
for individual requests for on-off switches because information in the media
and from the commenters indicated that many people misperceived the extent and
source of the risk associated with air bags. The agency was concerned that many
people who were not at risk for death or injury from an air bag would reduce
their safety by unnecessarily installing and using switches. Therefore, NHTSA
drafted the regulation granting the exemption to counteract that misperception
and its potential consequences. The regulation requires vehicle owners to first
read an information brochure explaining the actual risks associated with air
bags and what most owners can do to virtually eliminate the risks to themselves
and the users of their vehicle and to then submit a request for a switch to the
agency. The vehicle owner may obtain a switch only after the agency sends the
owner a letter authorizing a motor vehicle dealer or repair business to install
it. The regulation also requires dealers or repair businesses to provide the
vehicle owner with information about the potential safety consequences of using
the switch to turn off an air bag when they install a switch. In addition,
dealers and repair businesses must notify the agency when they install a
switch.
The agency has not proposed any of those procedural
provisions as part of the exemption from the make inoperative prohibition for
persons who modify vehicles to accommodate people with disabilities. More
specifically, the agency has not proposed to require that
vehicle owners or modifiers perform any of the tasks: fill out written
requests, certify the need for modifications, certify having read the
information concerning the safety consequences of modifications, or obtain
prior agency approval of their requests. Similarly, the agency has not
proposed to require that modifiers notify the agency of the
modifications they make or provide vehicle owners with information concerning
the safety consequences of the modifications.
The proposed exemption addresses the requests for
modifications based on objective physical inability to use an unmodified
vehicle, not any potentially overgeneralized or overstated fear of an item of
vehicle equipment, as in the case of air bags. Thus, there is no gap between
the actual need for modifications and the perceived need for them. Further,
there is a limitation on the modifications that vehicle owners can obtain under
the exemption. The modifications must be necessary to accommodate a particular
disability. There is little likelihood that persons lacking disabilities will
seek the types of modifications addressed by this proposed
exemption. Most such modifications have appeal only to those with a need for
them. In addition, most of these modifications are expensive. For example, a
fairly extensive modification to allow a quadriplegic to drive costs anywhere
from $27,000 to $80,000 (for the most advanced modifications). Even a
relatively simple set of hand controls costs between $300 and $500. Further,
the agency believes that most modifications, particularly the most extensive,
are paid for in whole or in part by organizations that generally require
individuals desiring vehicle modifications to be evaluated by an occupational
therapist (OT), or other appropriate professional 41 before vehicles
are modified. These organizations include the U.S. Department of Veterans
Affairs (VA),42 the states,43 or third party payers, such
as workman's compensation or disability insurers.44 The OT assesses
the severity of the person's disability and issues a prescription specifying
the vehicle modifications that are needed to accommodate the person's
disability.
A final factor that would tend to discourage persons without disabilities
from attempting to obtain the modifications at issue in this
proposed exemption is that those modifications take a
considerable period of time. This is in part because modifiers must typically
customize the vehicle to fit the person with a disability. For example, the
modifications for a quadriplegic could take from several weeks to several
months to complete. The modifier must take measurements and ensure that the
location and alignment of all the controls and equipment are accessible to and
operable by the person with a disability. In order to do this, a modifier must
often schedule several "fittings" with the person for whom the vehicle is being
modified.
Based on these considerations, the agency tentatively concluded that there
is no need to propose special procedural provisions to limit the availability
of modifications under the proposed exemption. There is little
risk that people would seek to have their vehicles modified unless the
modification was genuinely needed to accommodate a person's disability. The
agency also believes there is little risk that modifiers would agree to modify
vehicles for persons without disabilities. The exemption would not apply to any
modifications performed for the convenience of an able-bodied person and
modifiers would be subject to civil penalties for any such modifications. For
the same reasons, the agency tentatively concludes also that there is no need
for modifiers to inform the agency when it makes modifications under the
exemption.
- NHTSA seeks comment on whether its tentative conclusions are correct.
Is there a significant risk that individuals would seek modifications
unrelated to the accommodation of persons with disabilities? Should the
agency require any paperwork or record retention requirements to ensure
either that the intended beneficiary is a person with disabilities or that
the modifications are necessary to accommodate a specific disability or set
of disabilities?
Finally, virtually all the businesses who perform
vehicle modifications for individuals with disabilities are small businesses.
The agency does not want to impose any unnecessary requirements on these
businesses. The agency is concerned that requiring dealers and repair
businesses to submit a complete copy of an authorization form to NHTSA would
impose an unnecessary burden on these businesses. Under such a requirement,
modifiers would incur the additional costs associated with preparing,
printing, and maintaining such forms, and then mailing them after they have
been filled in and signed.
- NHTSA requests comment on whether it should require dealers and
repair businesses to submit such information to NHTSA and what the estimated
burden for these businesses would be.
IV. Additional Issues and Considerations
NHTSA strongly encourages those who modify vehicles for disabled drivers and
passengers to strive to ensure that disabled people receive a level of safety
that is as close as possible to that provided able- bodied drivers and
passengers. In order to operate, or ride in, motor vehicles, many disabled
individuals have no choice but to accept a lower level of safety in their
vehicle due to their disability and the technology that is currently available.
For example, a disabled person with limited range of motion may have to sit
extremely close to the steering wheel in order to drive. Sitting too close to
the steering wheel places that person at increased risk of head, neck, and
chest injuries in a crash.
NHTSA notes that in addition to the guidance that would be provided under
this proposal, there is guidance available from the best available industry
standards, such as the Society of Automotive Engineers (SAE) Recommended
Practices, Test Procedures, and Information Reports. The agency urges modifiers
to consult these materials. NHTSA encourages vehicle manufacturers to work
closely with those who modify vehicles for persons with disabilities to develop
vehicle designs which minimize the need for aftermarket modifications, and to
develop appropriate mobility arrangements, adaptive devices, and other hardware
that will work harmoniously with the requirements of all applicable
standards.
The agency believes that the proposed exemption would meet
the needs of most persons with disabilities seeking necessary vehicle
modifications, but recognizes that there might be instances in which relief
might be appropriate, but would not be available under the conditions of the
exemption. For example, additional exemptions may be required due to advances
in technology, amendments to the current standards, or to accommodate an
extremely rare disability or condition. Consequently, to the extent consistent
with this rulemaking, NHTSA would continue to review written requests for an
exemption from the make inoperative prohibition for vehicle modifications not
covered under this rulemaking.
V. Request for Comments
In addition to the questions raised above with respect to specific safety
standards andinop the procedural differences between today's proposal and the
existing exemption for air bag on-off switches, NHTSA requests comments about
the appropriateness of the provisions of the proposed
exemption. Among the specific issues are the following:
- NHTSA solicits comment on whether the standards
proposed for inclusion under the exemption are appropriate.
Are additional limitations needed with respect to these standards? The agency
is particularly interested in the results of any tests that have been
performed on modified vehicles and adaptive equipment. NHTSA seeks comment on
whether there are modifications that would necessarily take a vehicle out of
compliance with a standard but are not included in the
proposed exemption. For the standard requirements that NHTSA
is not proposing for inclusion in the exemption, the agency solicits comment
on whether the agency's analysis is correct or whether any of those
standards' requirements warrant inclusion in the exemption, and, if so,
why?
- NHTSA seeks comment on the use of vehicle modification prescriptions
in the vehicle modification industry. How often do vehicle owners provide
modifiers with a prescription? Do modifiers generally follow the
prescription's exact specifications or do they use the prescription as a
general guide to how they should modify a vehicle? How often do vehicle
owners provide modifiers with a license restriction identifying the needed
accommodation? Should NHTSA expressly require motor vehicle dealers or repair
businesses to obtain from vehicle owners either a prescription or a valid
restricted driver's license? Would such a requirement improve safety? What
effect would such a requirement have on individuals with disabilities? Would
requiring individuals without a prescription or license restriction to submit
a request to modify to NHTSA be unduly burdensome? Is such a requirement
needed to ensure that modifications are performed only to accommodate a
person's disability and not for the convenience of an able bodied
individual?
- The agency is aware of one situation in which a person with a
disability did not have a prescription because he did not seek medical
treatment due to his personal religious beliefs. The agency solicits comment
on whether people who do not consult medical professionals for religious
reasons consult some other trained professional for advice on vehicle
modifications. If they do consult another professional, what type of
professional is it? The agency also requests comment on whether there are
professionals other than doctors, occupational therapists, or driver
specialists who evaluate persons with disabilities and recommend vehicle
modifications.
- The agency seeks comment on the type of information that modifiers
currently provide consumers concerning the specific vehicle modifications
that they make to accommodate persons with disabilities and concerning the
potential safety consequences of those modifications. Should NHTSA require
the disclosure of such information by all modifiers? Should motor vehicle
dealers and repair businesses be required to identify any steps they would
take to minimize the vehicle's noncompliance with the particular
standards?
- The agency seeks comment on whether it should require modifiers to
disclose particular safety related information to the consumer. If so, what
information should that be? Should NHTSA require the information to be
presented in a particular way?
- The agency solicits comments on the appropriateness of requiring
modifiers to obtain a written authorization from the vehicle owner before any
modifications can be made. Do dealers and repair businesses already require
such authorizations? The agency solicits comment from modifiers who currently
obtain written authorization on how much time is involved in gathering and
maintaining the forms.
- The agency seeks comment on whether it should require dealers or
motor vehicle repair businesses to affix a permanent label to the vehicle to
ensure that subsequent purchasers are aware that the vehicle has been
modified and of the possible safety implications associated with such
modifications. If the agency were to require a label, what should the format
and the content of the label be? Where should it be placed? Do modifiers
currently affix labels? If so, what does the label look like?
- The agency seeks comment on the cost of vehicle modifications made to
accommodate people with disabilities.
- The agency requests comment on any state efforts to regulate the
business of modifying vehicles to accommodate a person with a disability and
the potential effect the proposed rule would have on those
states' regulatory efforts.
- Finally, the agency has posted information on vehicle modifications
and adaptive equipment at its Website
("www.nhtsa.dot.gov/cars/rules/adaptive"). The agency requests comment on
whether this information is presented in a useful way. Is there information
that is not available at the Website that modifiers and people with
disabilities would like to have posted?
VI. Proposed Effective Date
Since this proposal would remove a restriction on the modification of
vehicles for persons with disabilities, NHTSA anticipates making this amendment
effective 30 days after publication of a final rule under the Administrative
Procedures Act. 5 U.S.C. Sec. 553(d). The agency requests comment as to the
appropriateness of the effective date.
VII. Rulemaking Analyses and Notices
- Executive Order 12866 and DOT Regulatory Policies and Procedures
- NHTSA has considered the impact of this rulemaking action under E.O.
12866 and the Department of Transportation's regulatory policies and
procedures. This rulemaking document was not reviewed under E.O. 12866,
"Regulatory Planning and Review." NHTSA has analyzed this proposal and
determined that it is not "significant" within the meaning of the Department of
Transportation's regulatory policies and procedures. NHTSA has, therefore,
determined that a regulatory evaluation, designed to discuss the
benefits/disbenefits and consumer costs/cost savings of a proposal, is not
needed to support the subject rulemaking.
Clearly, modifying a vehicle in a
way that degrades the performance of certain federal motor vehicle safety
standards would produce some negative safety benefits for the occupants of the
vehicle. However, the number of safety standards affected would be very small
and the number of vehicles potentially modified would be very few in number.
Thus, the agency believes the disbenefits, if any exist, would be minimal. This
is essentially the trade-off that NHTSA is faced with when increasing mobility
for persons with disabilities--when necessary vehicle modifications are made,
some safety may unavoidably be lost.
It is cost prohibitive to have every
vehicle modification tested in advance for safety performance or safety
compliance. The vehicle modifications being made today to accommodate disabled
persons are based on engineering experience/judgment and have proven to be
successful in the real-world. For this particular proposal, which is
administrative in nature, no costs will be imposed by the agency's actions. The
cost of doing business for the vehicle modification industry will not be
changed by the subject proposal. If anything, there could be a cost savings due
to eliminating the requirements that the modifier contact the agency about
pending vehicle modifications.
- Regulatory Flexibility Act
- NHTSA has also considered the impacts of this notice under the
Regulatory Flexibility Act. Most dealerships and repair businesses are
considered small entities, and a substantial number of these businesses modify
vehicles to accommodate individuals with disabilities. I hereby certify that
this proposed rule would not have a significant economic
impact on a substantial number of small entities. As explained above, this
action would create a formal procedure to replace the current requirement that
dealers or repair businesses write to NHTSA and request permission each time
they need to modify a vehicle in a way that compromises a vehicle's compliance
with any standard to accommodate an individual with a disability. While most
dealers and repair businesses would be considered small entities, the
proposed requirements would not impose any mandatory
significant economic impact on them considering that: (1) for the vast majority
of cases, the agency believes the rule codifies standard industry practices and
procedures used to make vehicle modifications, (2) the
proposed rule would assist dealers and repair businesses in
making appropriate design choices, and (3) the proposed rule
would eliminate the costs associated with submitting a written request to NHTSA
to modify each vehicle as well as the costs associated with waiting for the
agency's response. Therefore, a Preliminary Regulatory Flexibility Analysis is
not required as the subject rule does not impose any significant costs on small
business entities.
- Paperwork Reduction Act
- NHTSA has analyzed this proposed rule under the
Paperwork Reduction Act of 1995 (P.L. 104-13) and determined that it would not
impose any information collection requirements as that term is defined by the
Office of Management and Budget (OMB) in 5 CFR part 1320.
- The National Environmental Policy Act
- NHTSA has also analyzed this proposed rule under the
National Environmental Policy Act and determined that it would have no
significant impact on the human environment.
- The Unfunded Mandates Reform Act
- The Unfunded Mandates Reform Act of 1995 (Public Law 104-4) requires
agencies to prepare a written assessment of the costs, benefits and other
effects of proposed or final rules that include a Federal
mandate likely to result in the expenditure by State, local or tribal
governments, in the aggregate, or by the private sector, of more than $100
million annually. This proposed rule does not meet the
definition of a Federal mandate, because it is completely permissive. In
addition, annual expenditures will not exceed the $100 million threshold.
- Executive Order 12612 (Federalism)
- The agency has analyzed this proposed rule in
accordance with the principles and criteria set forth in Executive Order 12612.
NHTSA has determined that this proposed rule would not have
sufficient federalism implications to warrant the preparation of a Federalism
Assessment.
- Civil Justice Reform
- This proposed rule has no retroactive effect. NHTSA is
not aware of any state law that would be preempted by this
proposed rule. This proposed rule would not
repeal any existing Federal law or regulation. It would modify existing law
only to the extent that it replaces an agency procedure under which dealers and
repair businesses had to obtain the agency's permission to modify a vehicle to
accommodate a person with a disability in a way that compromised the vehicle's
compliance with the Standard. This proposed rule would not
require submission of a petition for reconsideration or the initiation of other
administrative proceedings before a party may file suit in court.
VIII. Comments
NHTSA is providing a 90 day comment period. Interested persons are invited
to submit comments on this proposal. It is requested but not required that 2
copies be submitted.
All comments should not exceed 15 pages in length (49 CFR 553.21). Necessary
attachments may be appended to these submissions without regard to the 15 page
limit. The limitation is intended to encourage commenters to detail their
primary arguments in a concise fashion.
If a commenter wishes to submit certain information under a claim of
confidentiality, three copies of the complete submission, including the
purportedly confidential business information, should be submitted to the Chief
Counsel, NHTSA, 400 7th Street, SW, Room 5219, Washington, DC 20590, and two
copies from which the purportedly confidential information has been deleted
should be submitted to the NHTSA Docket Section. A request for confidentiality
should be accompanied by a cover letter setting forth the information specified
in the agency's confidential business information regulation. 49 CFR Part
512.
All comments received by NHTSA before the close of business on the comment
closing date indicated above for the proposal will be considered, and will be
available for examination in the docket at the above address both before and
after that date. To the extent possible, comments filed after the closing date
will also be considered. Comments received too late for consideration in regard
to the final rule will be considered as suggestions for further rulemaking
action. Comments on the proposal will be available for inspection in the
docket. The NHTSA will continue to file relevant information as it becomes
available in the docket after the closing date, and recommends that interested
persons continue to examine the docket for new material.
Those persons desiring to be notified upon receipt of their comments in the
rulemaking docket should enclose a self-addressed, stamped postcard in the
envelope with their comments. Upon receiving the comments, the docket
supervisor will return the postcard by mail.

4 The ADA sweepingly endorsed the rights of persons with
disabilities and greatly expanded the existing obligations of the public sector
towards persons with disabilities under the Rehabilitation Act of 1973 ( 29
U.S.C. sections 701 et seq.). The ADA created specific affirmative obligations
on private entities who conduct business with the general public.
5 NHTSA issues safety standards that specify performance
requirements for new motor vehicles and items of motor vehicle equipment. 49
U.S.C. 30111 and 49 CFR Part 571. Vehicle and equipment manufacturers must
certify that their new products comply with all applicable standards before
they sell their products. For vehicles manufactured by two or more
manufacturers, the final-stage manufacturer is ultimately responsible for
certifying the vehicle. A final-stage manufacturer is defined as a person who
performs such manufacturing operations on an incomplete vehicle that it becomes
a completed vehicle. 49 CFR 568.3. If a completed, certified vehicle is
modified prior to its first retail sale (other than by the addition,
substitution, or removal of readily attachable components), the person making
the modification is an alterer and is required to certify that, as altered, the
vehicle continues to comply with all applicable standards. 49 CFR 567.7.
Businesses that modify a vehicle after its first sale for purposes other than
resale are not required to certify that the vehicle, as modified, continues to
comply with the standards.
6 Section 30102 of 49 U.S.C. defines "dealer" as "a person
selling and distributing new motor vehicles or motor vehicle equipment
primarily to purchasers that in good faith purchase the vehicles or equipment
other than for resale."
7 Section 30122(a) of 49 U.S.C. defines "motor vehicle
repair business" as "a person holding itself out to the public to repair for
compensation a motor vehicle or motor vehicle equipment." NHTSA has interpreted
this term to include businesses that service vehicles by adding features or
components to or otherwise customizing those vehicles.
8 For example, Standard 208, Occupant crash protection,
requires certain vehicles to be equipped with air bags and to meet specified
injury criteria in a crash. Deactivating or removing the air bag would make
inoperative the air bag installed to comply with the standard. Cutting the knee
bolster could affect the femur load criterion and, therefore, degrade the
performance of the vehicle in a crash.
9 Section 30122(c)(1) of Title 49 of the United States
Code authorizes the agency "to exempt a person from" the make inoperative
provision if the agency "decides the exemption is consistent with motor vehicle
safety. * * *" The question of whether the agency has the authority to exempt
classes of people from the make inoperative prohibition or is limited to
exempting individuals on a case-by-case basis arose in the agency's rulemaking
on air bag on-off switches. 62 FR 62406; November 21, 1997. The agency believes
that Congress intended to permit an exemption based on classes of people. The
singular includes the plural, absent contrary statutory language or purpose.
Section 30122 neither contains any language nor has any purpose that would
preclude reading "person" in the plural. NHTSA notes that similar use of the
singular in 15 U.S.C. 1402(e), the statutory predecessor to 49 U.S.C. 30118(a)
regarding the making of a defect and noncompliance determination concerning a
motor vehicle or replacement equipment, has repeatedly been judicially
interpreted to permit NHTSA to make determinations regarding classes of
vehicles or equipment. Section 30118(a) was enacted in the same public law,
Pub. L. No. 93-492, that contained the make inoperative prohibition.
10 The report stated that "exemptions may be warranted
for owners with special medical problems, who require special controls. * * *"
H. Rep. accompanying 1974 Amendments to the Motor Vehicle Safety Act (1974).
11 NHTSA recently issued its first regulation exempting
motor vehicle dealers and repair businesses from the statutory prohibition
against making federally-required safety equipment inoperative so that they may
install retrofit manual on-off switches for air bags in vehicles owned by or
used by people whose requests for switches have been approved by NHTSA. 62 FR
62406; Nov. 21, 1997.
12 The agency believes that several factors account for
this situation. First, NHTSA believes that some modifiers may be unaware of the
statutory make inoperative prohibition. Others may not be aware that they
should seek the agency's permission before modifying a vehicle in a way that
compromises the vehicle's compliance with any of the standards. Third, some
vehicle modifiers believe that their modifications do not make inoperative any
device or element of design installed on or in a motor vehicle in compliance
with the standards. Agency staff discussions with modifiers revealed that much
of this was due to a lack of familiarity with the standards rather than poor
engineering judgment. In general, NHTSA found that once modifiers understood
and familiarized themselves with the standards, most modifiers exercised sound
engineering judgment with respect to modifying the vehicles. For example, the
agency learned that some modifiers were unaware that replacing the original
steering wheel and column with horizontal steering affected the vehicle's
compliance with Standard No. 203, Impact protection for the driver from the
steering control system, Standard No. 204, Steering control rearward
displacement, and Standard No. 208, Occupant crash protection. Some thought
they had only affected compliance with Standard No. 208's air bag requirement.
Thus, many modifiers only requested permission to deactivate the air bag. NHTSA
is increasing its efforts to raise the level of knowledge of the standards and
the make inoperative prohibition within both the disabled community and the
vehicle modification industry to address this problem. Finally, some dealers
and repair businesses who are aware of the need to seek permission simply
ignore that requirement because they consider the requirement to write a letter
for every vehicle modification onerous.
13 The agency notes that some of these modifications did
not adversely affect the vehicles' compliance with any applicable safety
standards and, therefore, did not violate the make inoperative prohibition.
14 This estimate is from the National Mobility Equipment
Dealers Association (NMEDA).
15 The majority of these requests were made in the past
few years. Since all of the modifications were based on the need to accommodate
a person's disability, the agency granted all of the requests.
16 NMEDA, a professional association composed of vehicle
alterers, modifiers, equipment manufacturers, occupational therapists (OTs),
and driver trainers, has issued recommended practice guidelines for particular
types of vehicle modifications, such as dropping a floor to accommodate a
wheelchair or installing a power seat base, to assist its members in modifying
vehicles safely.
17 NHTSA notes that NMEDA has tried to address this issue
by developing a Quality Assurance Program (QAP) and conducting crash tests of
modified vehicles. In addition, the agency is aware that alterers who also
certify vehicles built to accommodate persons with disabilities prior to their
first retail sale have also performed crash tests on modified vehicles.
18 For example, NHTSA has required manufacturers to
recall adaptive equipment, investigated complaints about a modified vehicle and
a hand control, participated in outside research groups concerned with modified
vehicles and adaptive equipment, and researched air bag interaction with, and
injury potential from, steering control devices.
19 See for example, Standard No. 213, Child restraint
systems, final rule, 51 FR 5335; February 13, 1986 and 49 CFR Part
571.213.S6.1.2.(a)(1)(I); Standard No. 222, School bus passenger seating and
crash protection, final rule, 58 FR 4586; January 15, 1993 and technical
amendment, 58 FR 46873; September 3, 1993; Standard No. 208, Occupant crash
protection, 58 FR 11975; March 2, 1993, amended Standard No. 208 to provide
manufacturers of light trucks and vans (LTVs) "designed to be driven by persons
with disabilities" an alternative to complying with the dynamic testing
requirement for manual seat belts at outboard seating positions.
20 The agency notes that industry members, including
NMEDA, and members of the disabled community have urged NHTSA to issue clearer
guidance in the area of modifying vehicles for the individuals with
disabilities.
21 For example, a paraplegic may need to drop the floor
of a vehicle and install a lift and hand controls to accommodate his entering
the vehicle and transferring to a power seat to drive, while a person with
limited range of motion in her right arm may simply need to install a knob on
the vehicle's steering wheel. Another individual may need to have the
right-front passenger seat removed and a wheelchair restraint installed so that
he may ride in the vehicle while seated in a wheelchair.
Further, two
paraplegics with similar limited range of motion could require different
modifications. One individual may be able to operate the vehicle with the
steering wheel originally installed by the manufacturer while another might
require a smaller steering wheel to be installed. The first modification would
not require removal of the air bag, the second would.
22 For a full discussion of the standards
proposed for inclusion in the exemption as well as some of the
standards not proposed for inclusion, see Section II. C. of
this notice.
23 The H-point is the manufacturer's reference point for
determining where the passenger's hip joint should be located for testing
purposes. The hip joint's location affects the head's location.
24 The H-point is the manufacturer's reference point for
determining where the passenger's hip joint should be located for testing

25 S5.1.1.27(b) of Standard No. 108 provides that: "Each
multipurpose passenger vehicle, truck and bus whose overall width is less than
