Inspection/Maintenance (I/M) Emissions Testing
Vehicles registered in Davis County, less than six (6) years old, are required to have an emissions test once every two (2) years. Any vehicle older than six (6) years old, and that is model year 1968 or newer, must receive an emissions test yearly. Refer to the Department of Motor Vehicles (DMV) website to see the specific emissions testing schedule.
Gasoline vehicles may be tested at any certified station. Emissions testing locations for diesel vehicles, however, are determined based on their Gross Vehicle Weight Rating (GVWR).
