Which component is necessary to check to ensure visibility while driving?

• A. Dash lights
• B. Windshield wiper blades
• C. Door locks
• D. Air conditioning

Answer: (B)

The windshield wiper blades are essential for ensuring visibility while driving, especially in adverse weather conditions such as rain, snow, or fog. Good wiper blades will effectively clear water or debris from the windshield, allowing the driver to maintain a clear view of the road and surroundings. Proper visibility is crucial for safe driving and helps prevent accidents.

The condition of dash lights, while important for ensuring that vital information about the vehicle is visible to the driver, does not directly affect the external visibility necessary for safe driving. Door locks are primarily concerned with security and safety regarding entry into the bus rather than visibility. Lastly, air conditioning contributes to passenger comfort but does not play a role in visibility. Thus, checking windshield wiper blades is a critical step in the pre-trip inspection process to ensure clarity and safety while driving.
