It is illegal in New Jersey (Since Feb 2003) to let either a gasoline or diesel powered motor vehicle idle for more than 
3 minutes, while the vehicle is not in motion. The only exceptions are as follows:

  • Vehicles picking up or discharging passengers (maximum 15 minutes)
  • Vehicles stopped in traffic or at a traffic light
  • Emergency vehicles used for emergency work, only when they are actively involved in emergency work.
  • A motor vehicle whose engine is used for powering another mechanical operation other than propulsion (like a bucket truck or backhoe)
  • Diesel vehicles stopped for more than 3 hours when the temperature is below 25 degrees Fahrenheit may idle for 15 minutes.
  • Vehicles with sleeper berths under certain conditions
