When to Test

Emissions tests are required in Las Vegas, North Las Vegas and Henderson for each annual renewal of passenger cars, trucks, RV’s, and motor homes. This includes:

  • • All gas-powered vehicles
  • • Diesel-powered vehicles with a manufacturer’s gross weight rating up to and including 14,000 lbs.
  • • 1968 model years or newer
  • • New vehicles in their third registration year

Please see dmvnv.com for a list of exempt vehicles.

An emission test takes only a few minutes to run and the results of the test are immediately transmitted to the DMV; you may then renew your registration on the Internet at dmvnv.com, at a DMV kiosk, orin person at any DMV office.

Emission tests are valid for 90 days.

Failed Tests and Waivers

If your vehicle fails, you must pay the cost of the test. Smog Hut can help you determine why your vehicle failed and how it may be repaired to pass the second test. Please note: a technician is required by law to test a vehicle without discussing possible fail issues with the vehicle owner beforehand. The technician cannot tell you your vehicle may fail prior to testing!

If your vehicle has failed twice, you may be eligible for a waiver after spending a min. of $450 on repairs at a 2G facility such as Smog Hut. To learn more about waivers, visit any of our three locations or give us a call. Note: diesel vehicles have different waiver requirements.

Dealer warranties on emissions components

Under federal law, emission components can be covered under warranty for up to 8 years or 80,000 miles, whichever occurs first. For example, if you need to replace a catalytic converter, call your car dealer and ask if it is under warranty. You will be eligible to have the repair done at no cost to you, thereby saving yourself hundreds of dollars.

Please see dmvmv.com “On-Board Diagnostics Testing” for more information on vehicle test failures and what conditions will cause a vehicle to fail.

Smog Hut’s North Las Vegas location is a state licensed 2G repair station. We can repair your vehicle and provide waivers.

  • Nevada uses On-Board Diagnostics (OBDII) testing for 1996 and newer light duty gas vehicles. The inspector will connect an analyzer to the OBD computer in your vehicle and read the data from the emission control systems.
  • A technician will visually check the following items on on light duty gas powered vehicles older than 1996 and all 1968 and later model heavy duty gas powered vehicles.
  • Gas Cap
  • Air injection system
  • Exhaust gas recirculation system
  • Catalytic converter
  • Fuel inlet restrictor

Diesel tests are run on a dynamometer using an opacity meter to read visible particulate emissions.

Full-time All Wheel Drive and Traction Control Diesels with a 184” wheelbase or less are tested on a special all-wheel drive dynamometer. Smog Hut at 2218 E. Cheyenne Ave., North Las Vegas, is currently the only location in Clark County capable of testing these vehicles.
