When you inspect your bus, what should you ensure is working?

The correct answer emphasizes the importance of rider signaling devices during a bus inspection. These devices, such as stop signals, lights, and other communication tools, play a crucial role in ensuring the safety of passengers and the proper operation of the bus. If these signaling devices are functioning correctly, they provide essential communication to other drivers and pedestrians, significantly reducing the risk of accidents and ensuring that passengers can safely disembark and board the bus.

While engine oil levels, fuel gauges, and seating arrangements are important for the overall functionality and safety of the bus, the signaling devices are directly linked to the safety of the passengers during transit. Ensuring that these devices are operational means that the driver's intent and the bus's status are clearly communicated, which is vital for public transportation safety.
