What should be checked for safety before driving a school bus?

Safety checks before driving a school bus are critical to ensure the safety of the children on board and the overall integrity of the vehicle. Among the options provided, checking the bus inspection report is an essential part of this process because it offers a comprehensive overview of the bus's condition. The report typically details any previous issues, maintenance history, and adherence to safety regulations. This is crucial for ensuring that the bus is roadworthy before embarking on any journey.

While it is also important to consider fuel efficiency and tire pressure, these aspects alone do not cover the full spectrum of safety checks required. Fuel efficiency can impact operational costs but is not directly related to immediate safety concerns, and while tire pressure is indeed a vital safety check, it is just one component among many that an inspection report would address. Therefore, relying solely on tire pressure or fuel efficiency without reviewing the inspection report would not fully ensure the safety of the vehicle. Thus, checking the bus inspection report encapsulates a broader perspective on safety that encompasses multiple factors.
