Plan an emissions testing trip in Denver.

The Air Care Lipan location is on S Lipan Street, while Denver SE is on E Warren Avenue. The diesel directory also includes W Alameda Avenue, W Mississippi Avenue, W 62nd Court, Sandown Road and E 49th Avenue addresses. These are separate destinations, not branches sharing one queue.

The Maintenance Shoppe is marked temporarily closed by the DMV source. Heavy-duty, light-duty and explicit diesel AWD capability vary across the other listings. Confirm the business can test the vehicle before comparing its location.

The cards distinguish the operator’s reported wait from ordinary hours and show the available source timestamp. An unavailable diesel wait is not zero, and a gasoline “Station Open” message is not a measured queue. Check directly before a near-closing trip; inspection time is additional to driving and waiting.

Each station page includes its source, verification date, phone and known vehicle capability. Google Maps and Apple Maps links use the public destination address. The finder can compare driving estimates after you choose a starting point; a city name alone is not your exact origin. Compare options around Denver.

These are outside the listed Denver locality. Distances are approximate straight-line measurements from the nearest listed Denver station with a sourced position, not from your home or a city-center boundary. Census address-range positions are approximate; distances are not driving miles or drive times.
