What is idle reduction?

Idle reduction refers to the technologies and practices that reduce the amount of time vehicles idle their engines. Reducing idle time saves fuel, reduces engine wear, and reduces emissions and noise.

Why is idle reduction important?

Idle reduction is important because idling wastes fuel, pollutes, and threatens health. An idling car can waste up to 0.5 gallons per hour, costing money and fuel. Each gallon of this fuel emits about 20 pounds of carbon dioxide. This leads to excess pollutants and ground-level ozone, which can damage lungs.

How can you reduce your idling?

For conventional vehicles, you can reduce your idling by simply turning the key when stopped for more than 10 seconds when not in traffic. As for hybrid and electric vehicles, these have built-in technology that shut off the engine when not in motion.
