Does a brand new vehicle need an emissions test?
A brand new vehicle that has never been registered and/or titled in any state is exempt from emissions testing for 4 years.
My vehicle failed the emissions test, what are my options?
Inspection centers in the Denver-Metro area are prohibited from performing repairs of any kind. If your vehicle fails the emissions test, Air Care Colorado will give you several pamphlets telling you:
- How to go about getting repairs.
- How to find a technician trained to repair emissions systems.
- The options available if your vehicle fails the emissions test a second time.
For vehicles retested within 10 calendar days of the initial test, the retest is free. If your vehicle fails a second time and you have made repairs to the vehicle, you may be eligible for a free diagnostic evaluation. Contact Air Care Colorado or call their Hotline at (303) 456-7090 for details. Click on their logo below to be taken directly to their website.
| Keep in mind that vehicles still under a manufacturer’s or dealer's warranty may be eligible for repairs under the terms of the warranty. |
Is there a difference between Colorado emission standards and other states?
Yes. Out-of-state emissions tests are not honored in Colorado. A valid Colorado emissions test is mandatory.
