Call 1-800-END-SMOG

The dirtiest cars are responsible for as much as 40% of all automotive pollution. Help us remind owners of smoking vehicles to keep their cars properly maintained.

Call 1-800-END-SMOG from a regular phone, or #SMOG (#7664) from a cell phone and provide the vehicle license number, make and model of the car, and where and when you saw it. The owner will get a letter suggesting he or she get the vehicle checked.

The Smoking Vehicle hotline is run by the California Air Resources Board, for more information, see

Or you may call us on the Business Assistance Line at 805-861-8868 and we will forward your complaint to the State program!
