Pollutants from motor vehicles are harmful to public health and create haze that reduces visibility. The goal of the vehicle-testing program is to ensure that Davis County vehicles are operating cleanly and efficiently. Getting polluting vehicles repaired or off the road helps everyone breathe easier. For further information, call (801) 546-8860.

Davis County Testing Center no longer tests gasoline vehicles.
