Do I Need a Test?
Nevada requires emission tests each year. Inspection stations in Nevada are privately owned and decentralized.
Passenger cars, trucks, RVs and motor homes need a test if they are:
Based in the urban areas of Clark or Washoe county;
Gasoline powered (regardless of weight or size);
Diesel powered with a manufacturer's gross vehicle
weight rating up to and including 14,000 pounds; and
1968 model year or newer
a new vehicle at its fourth registration. The first three registrations are exempt. Hybrids are exempt for five model years.
Emission tests are valid for 90 days. If the vehicle was purchased from a Nevada dealer, the test is valid for 180 days from the date of the test.
Any used car dealer in Nevada must provide a valid passing emissions test with any vehicle they sell that is going to be registered in Clark or Washoe counties. In private transactions, the test is the buyer’s responsibility.
If your check engine light is on, get your vehicle tested anyway. If repairs end up being costly, a failing test is the first step in the waiver process.
Check your gas cap if the light comes on suddenly. A loose gas cap is a common problem.
You can get a movement permit to drive the vehicle legally if the registration is expired.
If the light is flashing, stop immediately. This indicates a serious malfunction.
Had repairs done? Has your battery been replaced recently? Don't take your vehicle in for a test right away. The test will show "Rejected" even if the check engine light is off. 1996 and newer vehicles need to be driven under varying conditions for up to one week in order for the On Board Diagnostics system to run all of its tests.
Gasoline vehicles in Nevada must not emit visible smoke, regardless of the county where they are registered. Smoking vehicles can be subject to citation and/or mandatory testing.
Test Failures and Waivers
If your vehicle has failed the initial emission test, you must repair it and pass a second test to be eligible for registration. If it still fails after repairs, you may be eligible for a waiver if you meet the requirements below.
If your registration is expired or about to expire, you can get a movement permit online through MyDMV or at a DMV office. You may be charged late fees and/or cited by law enforcement if you operate a vehicle on public streets with an expired registration.
If the vehicle still fails after being repaired, it may be eligible for a waiver. Your vehicle must fail:
Carbon monoxide and/or hydrocarbon levels exceeding standards for 1968-1995 light duty vehicles and all heavy duty vehicles, or;
Illuminated “Check Engine” lamp for 1996 and newer light duty vehicles.
Waivers will not be issued to:
Vehicles eligible for warranty coverage.
Smoking Vehicles - The vehicle must be repaired with no limit on cost.
Emission Device Tampering – The vehicle must be repaired with no limit on cost.
A waiver is only valid one year. The vehicle must be repaired prior to the next registration year.
Emission components could be covered under warranty for up to 8 yrs or 80,000 miles, whichever occurs first, under federal law. See EPA Emission Warranty Coverage.
The vehicle must be repaired by a 2G Licensed Authorized Station to be eligible for a waiver. The waiver application must include receipts from the station showing that at least $450 has been spent on parts other than a catalytic converter, fuel inlet restrictor or air injection system, or on labor other than emission testing if the repairs evidenced by the receipt were directly related to the deficiency in emissions.
If the vehicle is not repaired at an authorized 2G station, it will not be eligible for a waiver, regardless of the cost incurred. See Business License Verification for a list of stations.
Smog Free Clark County Voucher program
The Clark County Division of Air Quality will pay up to $975 for emissions-related repairs on 1968-1999 vehicles. Owner income restrictions apply. See SmogFreeClarkCounty.com.
Waiver repairs may be made by a 2G Licensed Authorized Station or the owner. Vehicles repaired at a non-2G garage are not eligible for a waiver. See Business License Verification for a list of stations.
If the vehicle is repaired at a station, an application for a waiver must include receipts from the station showing that at least $200 has been spent on parts other than a catalytic converter, fuel inlet restrictor or air injection system, or on labor other than emission testing if the repairs evidenced by the receipt were directly related to the deficiency in emissions.
If the vehicle is repaired by the owner, the application must include receipts or other evidence that at least $200 has been spent on parts other than a catalytic converter, fuel inlet restrictor or air injection system purchased within 14 days after the initial emission test.
If you still fail after repairs - If you failed the initial test, did the repairs pursuant to your county's requirements, met the financial limit to obtain a waiver and your vehicle still fails for hydrocarbons/carbon monoxide or a Check Engine light, bring your vehicle, both failed certificates, and receipts for all repair work to a DMV Emission Lab to request a waiver.

Testing Area Maps
You must complete an emission inspection If your renewal notice says "Smog Check Required" or if you are registering a newly-purchased vehicle that requires a test.
Emission testing is required in the Las Vegas Valley (hydrographic drainage basin 212) and within a five-mile buffer zone around it. This covers the entire Mount Charleston area including Kyle Canyon and Lee Canyon Roads, Blue Diamond and Bonnie Springs.
The only exceptions are vehicles based in the community of Goodsprings, which is near the border of the buffer zone. The community of Jean is outside the buffer zone.
Emission testing is required in Reno, Sparks, Washoe Valley and most of the area west of Washoe Valley. Testing is also required in the areas north and east of Reno between Interstate 80 and the 40th degree of north latitude (about midway through Pyramid Lake).
The Emission Program
Diesel Testing and Enforcement
Nevada has annual testing for light-duty diesel vehicles and roadside enforcement for heavy-duty vehicles.
A vehicle which emits visible smoke will not pass an emission inspection and does not qualify for any waiver. Law enforcement may issue citations for visible smoke.
The Nevada DMV also operates the Smog Spotter program to encourage the public to report smoking vehicles online or by telephone. The DMV will investigate reports on any vehicle with a Nevada registration, including heavy-duty diesel trucks and vehicles based in rural areas. Online reporting is available in English and Spanish.
