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
