What action should a driver take if the bus engine overheats?

If the bus engine overheats, the safest and most appropriate action is to pull over, turn off the engine, and allow it to cool. This response is critical for preventing further damage to the engine and potential hazards such as fires. Continuing to drive while the engine is overheating can lead to serious mechanical failure or even total engine loss, which poses a risk not only to the bus and its passengers but also to other drivers on the road.

Stopping and turning off the engine immediately halts the source of the overheating, allowing the engine to cool down in a controlled manner. It's important to ensure that the vehicle is in a safe location away from traffic to protect both the driver and passengers. Once the engine has cooled, the driver can then assess the situation further or seek assistance if needed. This measured approach is crucial for promoting safety and maintaining the integrity of the vehicle.

Opening the hood while driving is also not advisable, as it does not provide the necessary cooling and poses risks, including the chance of an accident if the driver is distracted or if fumes are released while in motion.
