What action should be taken regarding the bus's lights during inspection?

During the inspection of the bus, it is essential to ensure that all lights function properly and are correctly aimed. This action is critical for several reasons. First, operational lights are vital for the safety of both the driver and other road users, as they signal intent and visibility. Properly aimed lights help prevent blinding other drivers and ensure that the bus is visible in various conditions.

Checking lights involves testing the headlights, tail lights, turn signals, and brake lights for both function and alignment. This comprehensive approach guarantees that all lighting systems are working effectively, contributing to the overall safety of the vehicle. Neglecting or overlooking the inspection of any lights can result in dangerous situations on the road, especially in low-visibility conditions or when signaling lane changes and stops.

The other options suggest complacency towards the inspection process, which can lead to serious safety lapses. Ignoring light checks or focusing on limited aspects can ultimately compromise the bus's operational integrity and safety standards.
