Municipalities across the country are spending millions of dollars on fuel used to idle vehicles that must keep their emergency lights flashing: police cars, fire trucks, ambulances, highway construction vehicles, public works trucks and more. The IdleRight Fuel Management System monitors the battery's condition and automatically idles your vehicle only when necessary, greatly reducing engine wear and fuel consumption. IdleRight provides substantial fuel savings, decreased engine wear and harmful emissions, while exceeding most states' anti-idling regulations
