Smoking Vehicle Hotline

Colorado’s smoking vehicle hotline program is designed to identify smoking vehicles, and to provide owners with information that will encourage them to voluntarily make needed repairs. The hotline gives motorists and others the ability to report smoking vehicles to the state Air Pollution Control Division by phone or e-mail.

The state Air Pollution Control Division then provides owners of smoking vehicles with information that will encourage them to voluntarily make needed repairs. Repairs to smoking vehicles are required if a vehicle fails a mandatory emissions test because of a visible smoke problem. The cause of such smoke must be corrected before the required emissions sticker can be issued.

Also, a police officer may stop a smoking vehicle, issue a ticket and order the owner to make corrective repairs. Colorado law provides for a $25 fine for the first violation of the smoking vehicle law. The fine for subsequent violations is $100 (C.R.S. 42-4-412, 413). Some local municipalities have additional ordinances and fines for operating a smoking vehicle.

 To report a smoking vehicle:

• Call (303) 692-3211

• E-mail the Smoking Vehicle Hotline at cdphe.smokeline@state.co.us

When calling or e-mailing about a smoking vehicle, if possible, please include whether the vehicle was diesel or gas powered and include the vehicle's license plate number.
