  • First time street legal ATV registrations. This includes ownership transfers for previously registered street legal ATVs.

Vehicles Sold by Dealers in Non-Emission Counties to Emission-County Residents

Utah law requires all licensed Utah dealers to assure vehicles they sell to residents of Cache, Davis, Salt Lake, Utah, or Weber counties meet emission testing requirements prior to issuing a temporary permit. However, because emission testing facilities are often not available in counties where emission testing is not required, the air quality administrators from the five emission-required counties have granted a limited emission test exemption.

If a vehicle is sold to a resident of Cache, Davis, Salt Lake, Utah, or Weber counties by a licensed Utah dealer whose place of business is located in a non-emission county, the dealer must:

The purchaser must:

  • Obtain an emission test certificate of compliance within 10 days of return to county of residence;
  • Provide a copy of Form TC-820, Exemption Affidavit for Utah Emission Testing to the local motor vehicle office with the application for plate, title and registration, and,
  • Send certificate of compliance and a copy of the TC-820 to the local Department of Health.

Vehicle/Hull Identification Number (VIN/HIN) Inspections

Inspections of identification numbers are required for all vehicles or vessels to be titled in Utah for the first time, unless the vehicle is new (MSO) and was acquired from an in-state dealer or in-state manufacturer. Safety inspection certificates are acceptable means of verification for your cars, trucks, and motorcycles providing that the VIN number is accurate on the safety inspection certificate.

Trailers, boats, off-highway vehicles, and snowmobiles require separate VIN or HIN inspections, which can be completed by a Utah peace officer or DMV employee. This inspection will be completed at any DMV office at no extra charge.
