Smog Check and Car Inspection in Utah

SUMMARY: Utah Safety & Emissions Inspections

Some vehicles are required to undergo safety and/or emissions testing for registration and registration renewal. Exact times, fees, and other factors vary depending on the vehicle's location and model year. When applicable, new residents are subject to the same testing procedures, as well as an additional VIN test.

The Utah Division of Motor Vehicles (DMV) and Department of Public Safety (DPS) work together to govern the state's safety and emissions testing programs. Continue reading for information about required testing, fees, how to handle test failures, and more.

New Utah Residents

If you've recently moved to Utah, you must register your vehicle within 60 days of arrival.

Additionally, all vehicles being titled and registered in Utah for the first time must undergo a vehicle identification number (VIN) inspection unless they were obtained from a Utah dealer or Utah manufacturer.

Any of the following agents can conduct a VIN inspection and complete the Certificate of Inspection (Form TC-661) for you:

  • Certified safety inspector.
  • DMV employee (out-of-state authorized agents are acceptable).
  • Approved contractor.
  • Utah peace officer (out-of-state peace officers are acceptable).

Bring the completed Certificate of Inspection and any applicable safety and/or emissions certificates to your local DMV office when you title and register your vehicle.
