What is a key reason for checking the lights during a pre-trip inspection?

Checking the lights during a pre-trip inspection is crucial to ensure visibility and communication with other drivers on the road. Proper functioning lights, including headlights, brake lights, turn signals, and hazard lights, play a vital role in maintaining safety while driving. When lights are operational, they help other drivers gauge the actions of the bus, such as stopping or changing lanes, which minimizes the risk of accidents. Additionally, good visibility ensures that the driver can see the road and navigate safely in various conditions, such as at night or in poor weather.

Ensuring the lights are working also contributes to the overall compliance with traffic laws. While other options mention aspects that could be considered during a broader operational context, none are as fundamental as the role lights play in safety and communication on the road.
