Emissions Extension Request

If an emissions test is required for a vehicle that is temporarily out of state, obtain an emissions extension by providing the following to the Boulder County Motor Vehicle Division:

  • Completed emissions extension form (DR 2376)
  • Results of passing emissions test, if testing is performed in the county where the vehicle is located.*
  • Provide a copy of current insurance
  • Renewal reminder postcard, if available
  • Registration payment by check or money order made out to Boulder County

* If emissions testing is not performed in the county where the vehicle is located, a VIN verification form (DR 2698) or an equivalent out-of-state form must be completed by either a local law enforcement officer or a motor vehicle employee from the state where the vehicle is currently located. Additionally, the vehicle must be emissions tested within 15 days of returning to Colorado.
