Somerset County Department of Health enforces NJDEP idling regulation in an effort to reduce air and noise pollution. Idling occurs when a motor vehicle with a diesel or gasoline engine is running but the vehicle is not in motion. Excessive idling causes an unnecessary release of air contaminants into the air in New Jersey, including fine particulates and air toxics.  New Jersey has laws which prohibit the idling of a vehicle for more than 3 minutes, with certain exceptions as explained below.
