Emissions 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.
You must have a valid Nevada test to complete any original registration or most renewals 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.
