Should you turn off your car when stuck in traffic?

Unless you drive a vintage, carburetor-equipped vehicle, you’ll save fuel and reduce carbon dioxide emissions by turning it off. That being said, we don’t recommend turning your car on and off in stop-and-go traffic; driving safely means being able to respond quickly to traffic conditions.

Should I turn my engine off at traffic lights?

Reducing vehicle idling will cut pollution and save you money. You may not be able to avoid keeping your engine running when you’re stopped at a traffic signal or stuck in slow-moving traffic. But other times idling is unnecessary.

Why do people turn their car off at a traffic light?

The concept of the stop-start system is simple. It automatically shuts off the engine when the vehicle is at rest to cut fuel use and eliminate idle emissions. It then restarts the engine automatically when the driver lifts off the brake (or puts in the clutch to select 1st gear) to get going again.

Should I let my car idle before turning it off?

Does turning your car on and off damage it?

Modern engines do not, in fact, need more than a few seconds or idling time before they can be driven safely.

Most people think the amount of fuel saved using a start-stop system is negligible, but in reality, that fuel burned while idling at a stop adds up quickly. A study by the Society of Automotive Engineers found that using start-stop can see a car’s fuel economy improve by over eight percent in heavy traffic.

Does Start Stop actually save gas?

Does stop-start help save fuel? Yes – in situations where you’re stationary with the engine idling, such as in heavy traffic or waiting for traffic lights to change, it will save however much fuel would have been used by the engine while the car is stationary.

Should you turn off your car’s engine when you drive it?

Does turning off your car use less fuel?

Unless you drive a vintage, carburetor-equipped vehicle, you’ll save fuel and reduce carbon dioxide emissions by turning it off. Some drivers think that idling uses less fuel than restarting, but our research has found that drivers save fuel and reduce emissions by shutting down for stops as brief as 10 seconds.

How long should you leave your car running before turning it off?

The general rule of thumb is that if your car is stationary for less than 10 seconds it’s not worth shutting it off. That does, however, leave big chunks of time when you are stationary when you can turn it off, for example:
