About Air Care Colorado

It is a centralized vehicle inspection program whose purpose is to reduce vehicle tailpipe emissions (particularly carbon monoxide) in the seven-county Denver metropolitan area -- Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas and Jefferson. The program began Jan. 2, 1995 and is operated under a contract with the Colorado Department of Public Health and Environment and the Colorado Department of Revenue. It requires that all 1982 and newer vehicles have an I/M 240 emissions test every two years at one of the 14 Air Care Colorado testing stations in the Denver metro area. These facilities are operated by Envirotest Systems, under the oversight of the two state agencies. 1981 and older vehicles are required to pass the idle emissions test annually at any Envirotest Air Care Colorado center or at any licensed independent testing center.
