Vehicle Inspection Requirements FAQ

For more information about safety, emissions, or VIN/HIN inspections, see Vehicle Inspections.

Do dealers perform required safety and emissions inspections?

Yes. Dealers must assure vehicles meet all safety and emission requirements before the vehicles are sold and a copy of the safety inspection certificate must be given to the customer at the time of sale. Safety inspections must have been done within eleven months prior to sale; emission inspections are also valid for eleven months.


  • New Vehicles with an MSO are exempt from safety and emissions.
  • Vehicles are not required to be inspected if being sold to residents of counties that do not require emission inspections. Dealers in non-emission counties have a special exemption when selling to residents of counties that require emission inspections.

What do I do if my vehicle won’t pass inspections because the dealer didn’t fix a mechanical problem?

If the vehicle is titled and registered in your name, you should file a complaint with the emission officials in the county in which the vehicle was inspected, or, for safety problems, contact the Utah Highway Patrol at (801) 965-4889. These agencies will investigate the complaint. If it appears the dealer violated the law, MVED would be contacted, would investigate and possibly file a criminal complaint. However, if you are still operating the vehicle on the 45-day temporary permit (you have not yet received your license plates from the dealer), file a complaint with MVED.

I bought a car from a dealer and they want me to bring it back in for inspections. What should I do?

Because the inspections are required for the vehicle to be registered, you will need to bring the vehicle back in for those inspections. If the 45-day temporary permit has expired, you may additionally file a complaint with MVED.

My vehicle will not pass inspection, what are my options?

If after resonable efforts your vehicle will not pass an emission inspection, you can contact the appropriate county to see if you qualify for an exemption. Salt Lake County – 385-468-3837; Davis County – 801-525-5100; Weber County – 801-399-7140; Utah County – 801-851-7600.

If after resonable efforts your vehicle will not pass a safety inspection, you can contact the Department of Public Safety at 801-965-4889 to see if you qualify for an exemption.
