What is one of the primary reasons to check the brakes in a pre-trip inspection?

The primary reason for checking the brakes during a pre-trip inspection is to ensure the bus can stop safely. Brakes are a critical safety component of any vehicle, especially for buses that carry passengers. Effective brake function is essential for the safe operation of the bus, allowing the driver to stop in a controlled manner to avoid accidents, respond to traffic conditions, and ensure the safety of passengers and other road users.

While factors such as fuel efficiency and aesthetic concerns might be relevant in other contexts, they do not directly impact the critical safety function that brakes serve. Prioritizing brake functionality during the inspection underscores the importance of safety in transportation, making it a non-negotiable focus during pre-trip procedures.
