The state of Utah has safety inspection requirements for cars, trucks, and on-highway motorcycles.

Beginning January 1, 2003, vehicles with model years less than eight years old need a safety inspection once every two years. Vehicles in this category that have even-numbered model years must have safety inspections in even-numbered years, and vehicles that have odd-numbered model years must have safety inspections in odd-numbered years.

Vehicles with model years eight years old and older must pass safety inspections every year.

Emissions Inspections

Emission inspections and certificates are required only in Davis, Salt Lake, Utah and Weber counties. Most diesel/gas-powered cars and trucks model year 1968 or newer must have an annual emissions test, which can be completed at service stations authorized to perform the test. An emission inspection may be made no more than two months prior to the renewal of the registration. The emission certificate must be submitted to the appropriate Motor Vehicle office as a condition of registration.
