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).

Utah Indoor Clean Air Act

The Utah Indoor Clean Air Act prohibits smoking or vaping in all enclosed indoor places that allow public access. It also prohibits smoking or vaping within 25 feet of the entrance, exit, or any open windows or vents of these places. It requires that these buildings display “No Smoking” signage that can be easily seen upon entry into the building. “No Smoking” signage is available from the Davis County Health Department. Contact the health department to request signage at (801) 525-5128.

To report indoor smoking or vaping in a public establishment, visit the Davis County Health Department website and submit a complaint on our “Report a Complaint” page.
