Nevada Emissions Testing Requirements
Most vehicles registered in Clark County are required to pass a Nevada emissions inspection before the registration can be renewed. The requirement generally covers gasoline-powered vehicles starting with the 1975 model year. New vehicles have an initial exemption period. Certain historic and specialty vehicles may also be exempt.
The Nevada DMV determines whether your specific vehicle is subject to the emissions testing requirement. If the DMV renewal notice for your vehicle requires a smog check, that means a state-certified emissions test must be completed and the result submitted to the DMV before your registration can be renewed.
What Happens During Your Emissions Test
