Where to Go

The Air Care Colorado Inspection and Maintenance (I/M) Program is a network of 18 stations conveniently located throughout the Denver-metropolitan area and the North Front Range. Additionally, 18 RapidScreen roadside data collection units are set up and rotated among state-approved locations throughout the program area.

Depending upon the vehicle, Air Care Colorado stations use three different testing methods to evaluate emissions as part of the overall emissions inspection. They are:

  • 1982-and-newer vehicles: either an I/M240 dynamometer (treadmill) test or On-Board Diagnostics (OBD) “plug-in” test
  • 1981-and-older vehicles: a two-speed idle test

Find inspection stations and RapidScreen sites near you, and diesel inspection stations and county motor vehicle offices.

LOW PROFILE RIMS & OVERSIZED TIRES - Please note that front-wheel and all-wheel drive vehicles with low-profile rim sizes 17-inches-or-larger in diameter or vehicles with wheel sizes larger than 34 inches must be tested on special dynamometers capable of testing vehicles with these unusual features. Please take your vehicle to the Sheridan, Boulder, Ken Caryl or Fort Collins stations for inspection. These are the only stations in the program area equipped with specialized dynamometers that can test these vehicles.
