Report illegal idling

Idling is the running of a vehicle’s engine when the vehicle is not in motion or being used. Idling is bad for the environment, your health, and your wallet.


Air Management Services responds to the public’s concerns about illegal idling of heavy duty diesel vehicles (trucks and buses over 8500 pounds) in Philadelphia by enforcing Air Management Regulation IX. You can help to protect and improve the city’s air quality by reporting idling of diesel trucks or buses.

For gasoline-powered and other vehicles, the Philadelphia Parking Authority and the Philadelphia Police Department enforce the limits of the Philadelphia Traffic Code 12-1127 and can respond to complaints of idling.
