There seems to be some confusion about the state emissions testing these days in Fort Collins. We are getting calls wondering if we do emissions testing for gas powered cars and trucks because we are a State of Colorado Licensed Diesel Emissions Testing Station. The new gas vehicle testing program is different as it is a centralized testing program run by Air Care Colorado. They are the only place you can take your cars and trucks for testing. The Fort Collins facility is located at 835 S.E Frontage Road, which is just east of Interstate Highway 25 and south of East Mulberry. If you know where the McDonald’s restaurant and the OtterBox warehouse is located, it is on that same road, accross from OtterBox.
