|
|
|
|
| 1. Issues Pertaining to Load Carrying Capacity: How accurate must I be in documenting any reduction in load carrying capacity? |
| When documenting a reduction in load carrying capacity, accuracy must be within one percent of scale reading.
If I weigh vehicles to determine reduction in load carrying capacity does the scale have to be certified and legal for trade?
No, but it must have a current calibration traceable to the National Institute of Standards and Technology (NIST, formerly the National Bureau of Standards). See http://www.nist.gov/.
|
|
| 2. Using the Exemptions: Who must register? |
| Any repair business or individual who modifies vehicles after the first retail sale to accommodate persons with disabilities must register to take advantage of any of the exemptions afforded under the rule.
The make inoperative prohibition (and so the exemptions) do not apply to individuals modifying their own vehicles, as long as they do not intend to make the changes for the purpose of resale. If you are making a modification to your own vehicle, Federal law does not apply, so you can do whatever you want (subject to any restrictions your state may impose). However, NHTSA urges individuals making such modifications to avoid unnecessary elimination of safety features.
|
|
| 3. Issues Pertaining to Load Carrying Capacity: What effect does the placement of a wheelchair tie down intended for use by an occupied wheelchair have on a vehicle's load carrying capacity? |
| If an original designated seating position is replaced by a wheelchair tie down intended for use by an occupied wheelchair, 150 pounds must be allocated for that seating position. If the seat is permanently removed, its weight may be credited to the post-modification load carrying capacity. (Lore, 4/25/02, http://www.nhtsa.dot.gov/cars/rules/interps/files/23668.rbm.html and Conaway, 4/25/02, http://www.nhtsa.dot.gov/cars/rules/interps/files/23087.rbm.html) |
|
| 4. Issues Pertaining to Load Carrying Capacity: What liability do dealers (automobile dealers in general as well as mobility dealers or modifiers) have if they sell a vehicle that is overweight? |
| We are speaking here only about the first retail sale of the vehicle. NHTSA's regulation requires manufacturers (49 CFR 567.4(g)(3)) and alters (49 CFR 567.7(b)) to label vehicles with the appropriate GVWR. They must also certify that the vehicle meets all applicable FMVSS at the time of alteration. If a vehicle is above GVWR it may well not be in compliance with several FMVSS, such as braking and tire standards. Once the vehicle is no longer in compliance, a dealer may not sell it under 49 U.S. C. Chapter 301 (formerly the Motor Vehicle Safety Act) and NHTSA can seek enforcement action. In addition, a dealer who knowingly sells an unsafe vehicle, whether new or used, may be liable under civil tort laws in the event of a problem with that vehicle. S/he may also be guilty of fraud. State laws address these issues. |
|
| 5. Designated Seating Positions: How do designated seating positions affect a vehicle's load carrying capacity? |
| A designated seating position is defined as "any plan view location capable of accommodating a person at least as large as a 5th percentile adult female, if the overall seat configuration and design and vehicle design is such that the position is likely to be used as a seating position while the vehicle is in motion..." (49 CFR 571.3).
When seating positions are modified, the load carrying capacity of the vehicle may change. For example, if a designated seating position is modified to accommodate a removable seat with a wheelchair securement station, used when the seat is removed, the weight of the new seat and 150 pounds for its occupant must be included in the computation of the vehicle's load carrying capacity. The weight of the old seat is credited as an increase in load carrying capacity.
|
|
| 6. Complying with the Exemptions: If I cut the knee bolster just a little, must I use the FMVSS No. 208 exemption? At what point is the knee bolster compromised? |
| When it is necessary to use the exemptions is up to the judgment of the modifier. Each vehicle model and each modification is unique, so NHTSA cannot make any blanket statements about what modifications will cause a vehicle to no longer comply with a safety standard. Therefore, if you do not use an exemption, then the vehicle must comply with the standard after modification, so when in doubt, use the exemption. Using the exemption includes labeling the vehicle, giving documentation to the client and saving a copy of that documentation, according to the regulation. In the case of mechanical hand controls, NHTSA has a research report available at http://www-nrd.nhtsa.dot.gov/pdf/nrd-11/handcontrol.pdf that can give you guidance on whether cutting the knee bolster would affect the injury criteria used in FMVSS No. 208. |
|
| 7. Designated Seating Positions: Does a wheelchair retention device qualify as a designated seating position? |
| The installation of a wheelchair retention device to restrain an unoccupied wheelchair as cargo is not a designated seating position. Therefore, the modifier is not required to allocate 150 pounds for that position. Once again, the customer must be informed if the weight of his or her wheelchair is included in the load carrying capacity (if the load carrying capacity has been reduced by 220 pounds). A wheelchair securement device intended for an occupied wheelchair is a designated seating position, for the purpose of determining load carrying capacity. You must allot 150 pounds for the occupant. |
|
| 8. Using the Exemptions: How does the rule define the "first retail sale?" |
| A modifier cannot use the exemptions unless the vehicle has already been sold to the consumer. The "first retail sale" for purposes of this rule is the point at which the seller of the vehicle and the end user enter into a sales contract that identifies a specific vehicle to be delivered. This definition only applies to vehicle modifications made to accommodate a person with a disability. |
|
| 9. Complying with the Exemptions: Does the "make inoperative prohibition" apply to all changes to a vehicle? |
| No. It means that a modifier must not make any changes that make the vehicle noncompliant with an applicable FMVSS, or s/he must make those changes so that the vehicle would comply with the standard after modification. Many changes can be made that have no effect on a vehicle's compliance with the standards. Other changes, while they might affect compliance if done one way, can be made some other way so as to preserve compliance. |
|
| 10. Using the Exemptions: When do I have to register? |
| Businesses must register no later than 30 days after they modify a motor vehicle for use by a person with disabilities. Since the rule became effective April 30, 2001, businesses that have a history of modifying vehicles for persons with disabilities should already be registered, if they wish to take advantage of the exemptions. If they have not done so, they should register immediately. If changes to the information in the original letter occur (such as a change of address), a letter containing the new information must be submitted no later than 30 days after the changes occur. |
|
| 11. Designated Seating Positions: Should the Veterans Administration and State Vocational Rehabilitation agencies require that a modifier meet the requirements of the make inoperative rule before they assign work to the modifier? |
| Whether a modifier chooses to use the exemptions depends on the type of modifications and how they will be made. Only those modifiers who use the exemptions are required to register with NHTSA, label vehicles, and give documentation to clients (all requirements of the Part 595 rule). Therefore, there may be modifiers doing legitimate work who are not registered to use the exemptions. This would be either because their work is such that certification is not affected (for example, installing a left foot accelerator) or because they are doing the work in a manner that preserves certification. |
|
| 12. Using the Exemptions: How do I register? |
| Prepare a letter stating:
Full name of the business (individual, partnership, or corporation),
Residence/address of the business and state of incorporation (if applicable), and
A statement that the business/individual modifies motor vehicles to enable people with disabilities to operate, or ride as a passenger in, a motor vehicle, and
A statement that the business plans to use the exemptions provided in 49 CFR 595.7.
Send the letter to:
Administrator, National Highway Traffic Safety Administration,
400 Seventh Street, SW,
Washington, D.C. 20590.
NHTSA maintains a database of all registered modifiers. To hasten your entry into the database, you can also fax, FedEx, or UPS a copy of your letter to:
Maximo Aviles, NVS-22101
400 Seventh St, SW
Washington, DC 20590
Fax 202-366-3081
|
|
| 13. Complying with the Exemptions: Can a modifier use the exemption for FMVSS 208 to disconnect air bags or install air bag on/off switches? |
| Yes, unless it is the only modification being made that would take the vehicle out of compliance; 49 CFR Part 595 Subpart B covers this situation. The new exemption to FMVSS 208 applies only where a retrofit air bag on-off switch cannot accommodate the individual's disability and the air bag system is affected in the course of a necessary modification. An example is deleting the air bag because a client needs a reduced-diameter steering wheel. The seating position must be supplied with a lap and shoulder safety belt meeting the requirements of FMVSS Nos. 209 and 210.
If the only thing you need to do to accommodate the vehicle user is to install an air bag on/off switch, follow 49 CFR Part 595 Subpart B. Use the make inoperative exemption for FMVSS 208 at 49 CFR 595.7(c)(14), if the client needs a switch or air bag deactivation in conjunction with other modifications for which you will be using exemptions under 49 CFR Part 595 Subpart C. If the only thing you plan to do that will take the vehicle out of compliance with any FMVSS is to deactivate the air bag, then the vehicle owner must write a letter to NHTSA's Chief Counsel requesting permission to do so, according to the instructions found on our web site at http://www.nhtsa.dot.gov/airbags/rule/section09.html.
|
|
| 14. Using the Exemptions: Is there anything else I have to do to use the exemptions? |
| Yes, modifiers must prepare written documentation that:
Identifies the vehicle that has been modified (this can be done with the VIN),
Contains a list of the FMVSS or portions of FMVSS, with which the vehicle may no longer comply and,
Identifies the new load carrying capacity (if the load carrying capacity has been reduced by more than 220 pounds). Modifiers should also inform the customer if the available load carrying capacity includes the weight of the user's wheelchair, if appropriate.
This documentation can be as simple as notations on your invoice for the work performed. You must provide a copy to the customer. You must also retain a copy for five years. You do not send a copy to NHTSA, unless asked to do so by us.
In addition, the modifier must affix a permanent label next to the original or alterer's certification label that:
Gives the modifier's name and physical address, and
States, "This vehicle has been modified in accordance with 49 CFR 595.6 and may no longer comply with all Federal Motor Vehicle Safety Standards in effect at the time of its original manufacture."
This documentation and labeling must be done for each vehicle modified.

| 15. Designated Seating Positions: What should someone, whether a vehicle modifier, vocational rehabilitation agency employee, or driver evaluator, do if s/he believes a modifier is doing work that does not comply with NHTSA's regulations? |
| What should someone, whether a vehicle modifier, vocational rehabilitation agency employee, or driver evaluator, do if s/he believes a modifier is doing work that does not comply with NHTSA's regulations? |
|
| 16. Issues Pertaining to Load Carrying Capacity: What is the intended meaning of load carrying capacity? |
| The term load carrying capacity was not defined in the make inoperative final rule but the intended meaning is the same as "vehicle capacity weight" as defined in FMVSS No. 110, Tire Selection and Rims. In brief, load carrying capacity is the Gross Vehicle Weight Rating (GVWR) minus the unloaded weight of the vehicle. (Lore, 4/25/02, http://www.nhtsa.dot.gov/cars/rules/interps/files/23668.rbm.html)
However, FMVSS No. 110 applies only to passenger cars and, under that standard, manufacturers are required to provide a car's load carrying capacity on a label. Therefore, when modifying a passenger car, the modifier has the load carrying capacity available. For vans, SUVs and pickups, many of the vehicle manufacturers provide the same sort of label, even though it is not required. If the load carrying capacity is not provided for these vehicles, the modifier must calculate the load carrying capacity as previously described.
|
|
| 17. Issues Pertaining to Load Carrying Capacity: What is the Gross Vehicle Weight Rating? |
| A Gross Vehicle Weight Rating is assigned to the vehicle by the manufacturer and "shall not be less than the sum of the unloaded vehicle weight, rated cargo load, and 150 pounds times the vehicle's designated seating capacity." (49 CFR 567.4(g)(3)).
"Unloaded vehicle weight" is defined as "the weight of a vehicle with maximum capacity of all fluids necessary for operation of the vehicle, but without cargo, occupants, or accessories that are ordinarily removed from the vehicle when they are not in use (49 CFR 571.3).
|
|
| 18. Issues Pertaining to Load Carrying Capacity: What is the Gross Axle Weight Rating? |
| The Gross Axle Weight Rating (GAWR) is the maximum weight that the designated axle system is designed to carry. It is set by the OEM and noted on the vehicle's original certification label. Alterers must determine whether their modifications affect the manufacturer's stated GVWR or GAWR. If they do, the alterer must specify the new GVWR or GAWR on the alterer's certification label (see 49 CFR 567.7). Note: A modifier or dealer should never accept an altered vehicle that does not have an alterer's certification label. |
|
| 19. Complying with the Exemptions: Do the Part 595 Subpart C exemptions cover the new advanced air bag requirements of FMVSS No. 208? |
| Not as of the date of this article. NHTSA is reviewing a petition for rulemaking that requests the agency to add these new systems to the make inoperative exemptions. |
|
| 20. List of portions of FMVSS for which make inoperative exemptions are available when vehicles are modified to accommodate persons with disabilities: |
| Exemptions are given for only 13 of our 56 motor vehicle standards, and then only under certain circumstances. For most of those 13 standards, the exemption is given only for particular portions of the standard. Those portions of the standards and the circumstances under which they may be made inoperative are listed below, where the number following the 'S' tells you the paragraph of that standard for which the exemption is allowed. The complete text of all FMVSS can be found in the Code of Federal Regulations in the volume containing Title 49, parts 400 to 999 (available from the Government Printing Office) or online at http://www.access.gpo.gov/nara/cfr/cfr-retrieve.html#page1 (Fill in the boxes on that web page like this: Title = 49, Part = 571, Section= the standard number you want to retrieve.)

|
| 21. Complying with the Exemptions: Is it necessary to deactivate the air bag and use the 208 exemption when installing a rim-mounted steering control device? |
| Not typically. Among the commonly used rim-mounted steering control devices (SCDs), NHTSA has not found evidence to suggest that the functioning of the air bag is degraded. Nor is there evidence that rim-mounted SCDs come off during a deployment. So, it does not appear necessary to deactivate the air bag just because you install a steering control device. For additional information on this issue, there are two research reports available from NHTSA. Call Gayle Dalrymple at 202-366-5559. |
|
| 22. Issues Pertaining to Load Carrying Capacity: What is a rated cargo load? |
| The term rated cargo load is not defined by regulation, but generally it is the GVWR of the vehicle minus the combined weight of the occupied designated seating positions (150 pounds times the total number of designated seating positions) and the unloaded vehicle weight. (Lore, 4/25/02, http://www.nhtsa.dot.gov/cars/rules/interps/files/23668.rbm.html) |
|
| 23. Using the Exemptions: How do I verify my registration and/or see other businesses who are registered? |
| All registered businesses and individuals are listed on the NHTSA web site. See http://www.nhtsa.dot.gov/cars/rules/adaptive/Modifier/Index.cfm, or call Maximo Aviles at 202-493-0227. The online database is updated about once a month. |
|
| 24. Issues Pertaining to Load Carrying Capacity: Does the "make inoperative rule" specifically require a modifier to weigh each vehicle before and after modification? |
| No. Any good faith method may be used to determine the reduction in load carrying capacity. In some cases, simply subtracting the weight of items removed from the vehicle and adding the weight of items added to the vehicle will work. However, the agency assumes the modifier will weigh the vehicle if this is the only way to determine whether the load carrying capacity has been significantly reduced by his or her modification. (Lore, 4/25/02, http://www.nhtsa.dot.gov/cars/rules/interps/files/23668.rbm.html)
If more than one modifier works on a vehicle, who is responsible for notifying the consumer if the cargo capacity is reduced by more than 220 pounds and who must put the modifier's label on the vehicle?
Each modifier must put a label on the vehicle and supply the consumer with the documentation required by 49 CFR 595.7(b) regarding his or her own work. The last modifier to work on the vehicle must inform the consumer if the original load carry capacity of the vehicle is reduced by more than 220 pounds, "after the modifications are completed" (49 CFR 595.7 (e)(5).)
