Diesel-powered cars and trucks need an annual emissions test
if they:
- have a manufacturer's Gross Vehicle Weight Rating of 10,000 pounds or
less, and
- are based in the testing areas of Clark or Washoe county, and
- are 1968 model year or newer
(new vehicles on their first and second registration are exempted; a test
is required upon a vehicle's third registration)
Please note that the manufacturer's weight rating is
used to determine whether an emissions inspection is required. The declared
weight rating used to assess registration fees may be different. Both will be
listed on your registration renewal notice, which will also indicate whether a
smog check is required.
Emissions tests are valid for 90 days.
You must have a valid test to complete any original registration or renewal if
the vehicle requires a test as listed above. This includes reinstatement
of a suspended registration.
Nevada requires used car dealers to issue a valid emissions
test, when required, on any vehicle they sell. In private transactions, the
test is the buyer's responsibility.

Light duty diesel
vehicles undergo testing on a dynamometer. The
technician will also perform a test for visible smoke
and a visual inspection of the emissions components.
You must renew your vehicle
registration by mail or in person at a DMV office. Diesel test results are not submitted to DMV electronically.
Please renew by mail and include the paper emissions test
receipt.
The maximum testing fee a station may
charge for a diesel emissions inspection is $43.50 in Clark
County and $39.00 in Washoe County.

Trucks and buses with a Gross Vehicle Weight Rating of
10,001 pounds or more are not required to undergo annual emissions
inspections. However, they must adhere to opacity standards for
visible smoke. These standards apply in all 17 Nevada counties and to
vehicles traveling from other states as well as those registered in
Nevada.

Opacity |
Visible smoke must not block more than the
listed percentage of light passing though it. Standards differ
depending on the year of manufacture of the engine.
Engine families which have been exempted by the California Air
Resources Board are also exempt in Nevada.

Nevada uses the Society of Automotive Engineers J1667 Snap Acceleration Test for exhaust opacity measurements. Emissions control
technicians have mobile equipment and conduct courtesy inspections of
Nevada-based fleets at the request of fleet owners.
|
|
DMV also conducts random road side tests at weigh stations
throughout the state and operates an on-the-road
diesel enforcement program.
Teams
consisting of a sworn police officer and an emissions inspection
technician patrol the highways in marked vehicles. They are able to pull over any diesel vehicle,
conduct a roadside test and inspection and issue a citation if
appropriate. Currently, two teams operate in Clark County and one in Washoe County.

|
|
|
|
Violators can be issued administrative citations. Fines are waived for a first
offense if the vehicle is
repaired and evidence of the repairs is presented to the department within
45 days.
Violators who do not repair the vehicle are subject to fines of $800 or more. DMV can also
order a vehicle removed from the highways.
