What should be checked in a pre-trip inspection of a school bus?

In a pre-trip inspection of a school bus, checking the condition of the tires and brakes is crucial for ensuring the safety and functionality of the vehicle. Tires must be in good condition, properly inflated, and free from excessive wear or damage to maintain traction and handling. Likewise, brakes must be thoroughly inspected to ensure they are responsive, effective, and free from leaks. Since school buses carry students, having reliable tires and brakes directly impacts the safety of all passengers.

Other options, while they may concern the upkeep or comfort of the bus, do not prioritize the essential safety factors critical for transporting students. The radio and air conditioning systems are important for driver comfort and passenger experience but are secondary to safety requirements. Checking interior cleanliness contributes to maintaining a healthy environment but does not affect the mechanical reliability of the bus. Finally, examining the exterior paint job might be part of regular maintenance, but it does not influence the bus's operation or safety during transit. Therefore, prioritizing tire and brake condition is fundamental in a pre-trip inspection.
