What Needs Emissions Testing in Colorado?
Although there are specific exemptions that can be found on Colorado’s emissions homepage, here are the general rules for what needs testing.
For 1982 and newer vehicles: An I/M 240, or enhanced emissions test, is mandatory for gasoline-powered passenger vehicles and light trucks every two years at an approved Air Care Colorado center. Your vehicle registration renewal postcard will indicate if a test is needed or not.
For 1981 and older vehicles: A two-speed idle test, for gasoline-powered passenger vehicles and light trucks, is required every year at an approved Air Care Colorado center.
For specific information on emissions testing for heavy duty vehicles, vehicles that have recently changed ownership, vehicles that are not registered in the region but regularly driven in the area, and other special cases you can visit Air Care’s Testing Requirements page. There are also additional requirements for new residents.
If, after reading the provided information online, you still have any questions about needing an emissions test, given your particular circumstances, you can call the Air Care Colorado Hotline (303-456-7090) or your county motor vehicle office.
How Much Does it Cost to Have an Emissions Test in Colorado?
The inspection fee for an I/M 240 (enhanced emissions test) is $25. The inspection fee for a two-speed idle test is $15. If upon completing the first emissions test your vehicle fails, one retest performed within ten calendar days of your first test will be given for free.
If after failing a first test, your vehicle gets repaired and still fails a second test, Air Care Colorado will offer, for free, some help in diagnosing the problem. (For more information or for setting up an appointment, call 303-744-2442 and press 3.)
What Should I do Before Getting my Vehicle Tested?

Air Care Colorado recommends making sure your tires are properly inflated, your brakes are in good condition, no part of the vehicle smokes, and the integrity of the exhaust system is intact.
