Why should fluid levels be checked as part of the pre-trip inspection?

Checking fluid levels during the pre-trip inspection is crucial to prevent mechanical failures and ensure the safe operation of the vehicle. Fluids such as engine oil, coolant, brake fluid, and transmission fluid play vital roles in the performance and reliability of the bus. Low fluid levels can lead to overheating, inadequate lubrication, or brake failure, all of which can compromise safety and lead to potentially dangerous situations on the road. Therefore, confirming that all necessary fluids are at appropriate levels is essential for maintaining the proper functioning of the bus and ensuring the safety of the driver and passengers.
