MenuThe State of Nevada requires vehicle emissions tests before every yearly registration renewal as well as for most original vehicle registrations. The Nevada Department of Motor Vehicles runs the state’s vehicle testing program.
There are many vehicles the State of Nevada requires to pass a smog check, they include Passenger cars, trucks, RVs, and motorhomes. If one of these vehicle types also fall into the following categories, they must get a smog check:
If your vehicle falls under one of the following categories, it is exempt from testing:
The State of Nevada allows smog check locations to be privately owned. Because of this fact, smog check fees vary by location. There is a yearly maximum amount the state allows smog check locations to charge by law. This amount changes annually.
All non-exempt vehicles must pass a yearly vehicle emissions test in the State of Nevada by law. The Nevada DMV sends out renewal and first – time registration notices in the mail. The notice will indicate if and when the test must be completed. Emissions tests are usually very convenient since most Nevada inspection stations are privately owned and decentralized. Emissions tests stay valid for 90 days after the initial test date of completion. Vehicles must pass a Nevada smog check in order to receive an original registration, and also for most renewals. Nevada DMV testing personnel usually perform two types of emissions test on Nevada-registered vehicles:
On-Board Diagnostic Tests – Nevada test personnel will administer an ODBII test on most motor vehicles made in the 1996 or newer model years. The OBDII system installed in U.S. manufactured vehicles made in the 1996 and newer model years is a mechanical issue early-warning system. The system records the vehicle’s performance by administering a specific kind of test referred to as a “Monitor”. Monitors test a vehicle’s primary emissions components and subsystems. While the key is in the ignition and the engine is off, a test technician will make sure the vehicle’s DLC (Data Link Connector) works properly. Then, the test technician hooks an emissions diagnostic tool up to your vehicle’s DLC using a cable to allow the technician’s diagnostic tool to communicate with the vehicle’s OBD II system. The Nevada test technician can check your vehicle’s engine and emissions systems, and see if any monitors state a “Not Ready” status. If there are too many monitors stating a “Not Ready” status, then the vehicle will not pass the test. The test personnel can complete the test in around 2 minutes.
Two-Speed Idle Test (PC – TSI): Nevada test personnel measure the vehicle’s emissions while the vehicle remains in Park or Neutral gear and rev the vehicle’s engine at two different RPM (Revolutions Per Minute) levels. Some older vehicles get tested while on a dynamometer.
Vehicle owners will know immediately if they pass the test and will receive a vehicle inspection report immediately. If getting a first-time registration, vehicle owners must go to a Nevada DMV office location. Vehicle owners getting registration renewals, have several different registration options.
If your vehicle fails an initial smog inspection, the vehicle owner must get the vehicle repaired and retested. If the vehicle does not pass the second test, then the vehicle owner may be eligible for a waiver.
While waiting to get a vehicle retested the vehicle owner must have insurance and a valid registration, or a movement permit in order to operate a vehicle on Nevada public streets. If a vehicle owner’s registration expires before they are able to get their vehicle to pass a smog inspection, they can get a movement permit at the DMV after presenting their registration or other proof of ownership. However, owners who do not get their vehicles to pass a smog inspection before their registration expires can still be charged a late fee and cited by law enforcement if they operate their vehicle after their registration expires.
New residents who recently moved to Nevada must register their vehicle within 30 days of becoming a Nevada resident. Depending on the type, year, and weight of the vehicle, new residents may be required to get their vehicles smog checked once they obtain Nevada residency. The Nevada DMV recommends new residents to bring their vehicles to a certified inspection facility as soon as possible after moving to Nevada so as to have plenty of time to complete any necessary repairs or to apply for waivers. Keep in mind, the State of Nevada does not recognize or honor out-of-state smog or emissions tests.
Nevada exempts new vehicles from smog checks for the first 2 years. Used car dealers must issue valid emissions test certificates when selling a vehicle. The buyer must get a vehicle to pass a smog check and obtain a valid smog certificate if they buy a vehicle from a private seller.
Nevada vehicle owners may want to get their vehicles tested as soon as they receive their first testing notice. Allow extra time to get any needed repairs done before your registration expires. Also, if a vehicle owner plans to be out of town during the date when their registration expires, planning early will give owners time to meet the deadline.
