The Colorado state emissions testing program covers the counties of Adams, Arapahoe, Boulder, Denver, Douglas, Larimer, Weld, Jerrerson, and Broomfield. The rural areas of Adams and Arapahoe counties east of Kiowa Creek are excluded.
There are eighteen emissions testing service centers that all vehicles may be tested at. If your vehicle is from 1981 or prior it may be tested at an independent testing location. If you need information on testing centers you can call 1-303-692-3270 or if you have a diesel powered vehicle you would call 1-303-205-5603.
