Reporting Smog
Call 1-800-END-SMOG or submit a Complaint Form for Smoking Vehicles online.

Reporting a Smoking Vehicle
When you call 1-800-END-SMOG to report a smoking vehicle, you will be asked to provide the following information:
  • Vehicle Type
  • License Plate Number
  • Date, Time, and Location of the Incident
  • Make and Model of the Vehicle

AQMD checks this information against Department of Motor Vehicles records to determine the name and mailing address of the vehicle's registered owner. AQMD then sends the owner an advisory letter describing when and where the vehicle was seen smoking and recommending vehicle maintenance or repair. The letter also asks the owner to submit proof of repair of the vehicle to reduce smog.
