Air Care Colorado

Jason Winford's answer is correct, but not complete. Some (not brand new) cars are issued a 2 year emissions cerificate, some are issued only a 1 year certificate (depends on vehicle type/age/and emission test values). Additionally, if you happen to drive past one of the "mobile emissions testing" devices, you can receive a roadside "emissions test passed". This is stored in the state system, and linked to your license plate number. If you pass this way, your renewal card that comes in the mail will say so. All that is required for test is to have your car warmed up, take your car to the testing center, have it tested, and pay the fee.

Yes. Open and operating normally.

Yes, they do.

Problem. I don't think so

If your title is still branded salvage, then they emission station can not perform the required check. That must be performed by a POST certified inspector. Those inspections are performed by the Colorado State patrol. If you're title states rebuilt, then the emission station can perform the VIN inspection, as well as the required emission inspection.

Yes they do, search air Colorado wait times, the times update every 15 mins

They will get vin from car, just need money to pay

It depends in the year of the vehicle. 2005 and newer will fail. 2004 and older they will still test, and may pass.

They don't list any differnce for diesel. 1982 and newer vehicles require an enhanced emissions test every two years at a cost of $25. 1981 and older vehicles require a two-speed idle test every year at a cost of $15.00. Vehicle Identification Number (VIN) verifications are also available at a cost of $20.00. Payment for the test may be made by cash, check or charge. (Please make checks payable to: ACC.)
