Location & Wait Times

As a convenience for motorists, Air Care Colorado maintains real-time estimates of the expected wait at each inspection facility. The current wait times are listed on the maps page on this website.


If a station's waiting queue (inside the ticket gate) is full, with 10 or more vehicles waiting outside the building, the station will close the gate. We apologize for any inconvenience this may cause, but it is necessary to enable our staff to complete their duties by 6 PM. We appreciate your understanding.


LOW PROFILE RIMS & OVERSIZED TIRES - Please note that front-wheel and all-wheel drive vehicles with low-profile rim sizes 17-inches-or-larger in diameter or vehicles with wheel sizes larger than 34 inches must be tested on special dynamometers capable of testing vehicles with these unusual features. Please take your vehicle to the Sheridan, Boulder, Ken Caryl or Fort Collins stations for inspection. These are the only stations in the program area equipped with specialized dynamometers that can test these vehicles.

Avoid waiting. Currently, due to the COVID-19 related station closures, all open stations are extremely busy. Mondays all day and early mornings are the busiest times. Mid to late afternoons are the least busy times. High volume times to always avoid are Mondays, the first business day after ANY holiday, and the last few days of the month.

Wait Time Note: Please keep in mind that the wait times are estimations based on recent station activity. The wait times are updated approximately every 15 minutes.
