What should you listen for while driving the bus?

Listening for engine knocking, clicking, or tapping while driving the bus is crucial because these sounds can indicate mechanical issues that may compromise the vehicle's performance and safety. An engine emitting knocking or tapping noises typically suggests internal problems such as worn bearings, low oil pressure, or issues with the fuel mixture. Addressing these noises promptly can prevent further damage and maintain the bus's reliability, which is essential for the safety of the passengers.

While excessive smoke from the exhaust can also signify engine trouble, it is not always audible. Harsh weather changes, though important to be aware of, do not directly affect the mechanical operation of the bus in the same way sounds do. Gauges fluctuating can signal a problem, but they require visual attention and are not related to what you should actively listen for while operating the vehicle. Therefore, focusing on the sounds coming from the engine helps identify potential issues that need immediate attention.
