Idling cars, trucks, school buses, public and private shuttle buses, and off-road construction equipment all contribute to the degradation of local air quality. Current state regulations limit engine idling for both diesel and gasoline vehicles to three minutes with limited exceptions. Violations can be issued by New Jersey Department of Environmental Protection (DEP), Union County Environmental Health Officer, or the Fanwood Police Department. Call the DEP 24-hour, toll-free hotline at (877) 927-6337 or use the WARN DEP app. To report idling violations, call the police non-emergency number at (908) 322-5000. *Please do not call 911.
