What should be checked before starting the bus?

Before starting the bus, it is essential to ensure safety by checking that no one is around, verifying there are no puddles underneath (which could indicate leaks), confirming that the bus is in neutral, and that the parking brake is engaged. This thorough check helps prevent accidents by ensuring that the bus remains stationary and that anyone nearby is safe before the vehicle is put in motion. The other options, such as engine temperature, fuel level, and tyre pressure, are important checks but are secondary to the immediate safety concerns associated with starting the bus. Safety should always take precedence, making this comprehensive pre-start check a critical part of bus operation procedures.
