What does L-A-B stand for in the context of school bus operations?

In the context of school bus operations, L-A-B stands for "Lights, Audio, Brakes." This acronym serves as a useful mnemonic for bus drivers to remember crucial systems that must be checked before operation.

Understanding the components of this acronym highlights the importance of ensuring that all lights on the bus are functioning correctly for visibility and safety. The audio system is vital for communication within the bus, allowing drivers to monitor if there are any announcements or alerts that could affect safety. Finally, brakes are essential for control and stopping the bus safely, making regular checks of the brake system critical.

While the other options include various vehicle checks, they do not align with the established industry practice encapsulated by the L-A-B acronym. This specific acronym emphasizes the priority of lights, audio systems, and brake functionality in the pre-operational checklist for school bus drivers, contributing to the overall safety of the students being transported.
