Sure you need a test?
Be sure before you present your vehicle for testing!
State regulation requires testing centers to test ALL vehicles presented. Under this regulation, emissions inspectors are prohibited from judging whether or not your vehicle needs a test. No refunds can be given for emissions tests that were not due. If you are not sure, call the Air Care Colorado Hotline at 303-456-7090.
