From the point of view of efficient driving and safety, when is it advisable to switch off the vehicle's engine?

Question

DentroTest · Accepted Answer

The correct answer is during prolonged stops (lasting more than 60 seconds). Keeping the engine running (idling) when the vehicle is not moving consumes fuel unnecessarily (between 0.5 and 1 liter per hour) and emits polluting gases and noise. Regulations and tips: Tunnels and Level Crossings: It is mandatory to switch off the engine if the stop in a tunnel or level crossing lasts more than two minutes, although for efficiency it is recommended to do so after 1 minute. Traffic Lights: It is not recommended to switch it off manually at common traffic lights, as stops are usually short and constant restarting can wear out the battery and starter motor (unless the vehicle has an automatic Start/Stop system). 5 Minutes: Waiting 5 minutes is inefficient; the saving threshold starts much earlier.
