Have you noticed vehicles putting out excessive amounts of smoky exhaust while being driven? These vehicles are generally gross polluters and should have repairs performed to allow the vehicles to meet emission requirements.
If you see such a vehicle being driven and would like to report it for testing, please make note of the license plate number, a description of the vehicle (make and color, etc.), the location, the date and time when you saw the vehicle.
We do not accept anonymous complaints. Please provide your name and phone number. Your information will remain private and won't be disclosed to the public. If you prefer, you can also call (801) 399-SMOG(7664).
