Vehicle Inspection

DEQ values the watchful eyes and ears of citizens concerned with our environment.

If you see a car or truck that shows visible exhaust for more than 10 seconds, you can call 1-888-997-7888 or click the link below to report the vehicle. Please complete the questions below as completely as possible and click the "Submit" button. DEQ may contact the driver of the vehicle, but does not conduct formal enforcement activity. Any city, county or state police officer who witnesses excessive smoke from a motor-vehicle can issue the driver a citation. You may contact your local law enforcement agency and file a non-emergency complaint.
