During a pre-trip inspection, what should you check about the lights?

During a pre-trip inspection, checking that all exterior lights are operational, including turn signals and brake lights, is crucial for safety on the road. Each of these lights plays a significant role in communication with other drivers. Turn signals indicate a driver's intent to change lanes or turn, while brake lights alert others that the bus is slowing down or stopping. Ensuring these lights are functioning properly helps prevent accidents and enhances the overall safety of the vehicle and its passengers.

The other options may focus on aspects of the lighting system that aren't as critical to a pre-trip inspection. For example, while reflective tape can be helpful for visibility, it is not a standard requirement for all bus lights. The color of the lights is generally standardized for specific types of vehicles, but it is not the primary concern during a pre-trip check; operational readiness is more critical. Automatic adjustment of lights is not a typical feature for most buses and is less relevant to the standard pre-trip assessment, which simply requires the driver to confirm that all lights are functioning properly.
