Anti-idling
Greater Mercer TMA Works With Communities and Schools to Reduce Idling
Idling occurs when a vehicle is turned on, but is not in motion. Vehicle idling is of great concern because it causes severe health issues, damages the environment and is illegal. NJ State Law prohibits idling a vehicle (diesel or gasoline) for more than three minutes.
“Young Lungs at Work” anti-idling toolkits are available for schools and municipalities. Presentations for K-6 are available upon request.

In addition, Idle Free Zone information is available for businesses and concerned citizens.

Idling Facts
  • More than 10 seconds of idling consumes more fuel than restarting your engine.
  • One hour of idling burns about one gallon of gasoline and gets ZERO mpg.
  • Idling can decrease the life of your engine components, including cylinders, spark plugs, and exhaust systems.
  • An idling engine isn't working at ideal operating temperature and fuel doesn't undergo complete combustion.
  • Vehicle exhaust is one of the leading sources of toxic air pollution.
Idling Myths
An engine should be warmed up before driving.
Idling is not an effective way to warm up your vehicle, even in cold weather. The best way to do this is to drive the vehicle. With today's modern engines, you need no more than 30 seconds of idling on winter days before driving away.
Shutting off and restarting your vehicle is hard on the engine and uses more gas than if you leave it running.
Frequent restarting has little impact on engine components like the battery and the starter motor. Component wear caused by restarting the engine is estimated to add $10 per year to the cost of driving, money that will likely be recovered several times over in fuel savings from reduced idling. The bottom line is that more than ten seconds of idling uses more fuel than restarting.
