What feature should operate correctly in a pre-trip inspection related to the windshield?

• A. Heating system
• B. Windshield wiper blades
• C. Sun visors
• D. Navigation system

Answer: (B)

In a pre-trip inspection for a school bus, it is crucial to verify that the windshield wiper blades operate correctly. This feature is vital for ensuring visibility in adverse weather conditions, such as rain or snow. Properly functioning wiper blades help remove water, debris, and other obstructions from the windshield, allowing the driver to see clearly and respond to potential hazards on the road.

While other features like the heating system, sun visors, and navigation system may enhance comfort or convenience, they do not directly impact safety in the same way that functioning wipers do. A clear windshield is essential for safe driving, making it a priority during pre-trip inspections to confirm that the wiper blades are in good condition and able to perform their intended function effectively.
