What should be assessed about the bus’s lights and signals during the inspection?

• A. They should create a unique pattern
• B. They must all work and be properly adjusted
• C. They can be broken if a spare is available
• D. They should match the bus’s color scheme

Answer: (B)

The assessment of the bus’s lights and signals during a pre-trip inspection is crucial for ensuring safety on the road. All lights and signals must function correctly and be properly adjusted. This includes headlights, brake lights, turn signals, and hazard lights, as they provide critical information to other drivers and pedestrians regarding the bus's movements and intentions.

When lights and signals are functional and correctly positioned, they enhance visibility and communication, reducing the risk of accidents. Proper adjustment ensures that the light beams are not misaligned, which could either blind other drivers or fail to adequately illuminate the road. Thus, focusing on the operational readiness of these components ensures the safety of the bus's occupants as well as others on the road.

The other options suggest aspects that do not pertain to the primary function and safety requirements of lights and signals during a pre-trip inspection. For instance, creating a unique pattern does not relate to functionality, and the idea of using broken lights if spares are available does not meet safety regulations. Matching the bus color scheme is irrelevant to the operational requirement of lights and signals. Therefore, ensuring that all lights and signals are working and well-adjusted is fundamental for a thorough and effective inspection process.
