What is an important aspect in the maintenance of the bus windshield wipers?

• A. The wipers must be replaced yearly
• B. The wipers must be long enough to cover the windshield
• C. The wipers must be clean and in good working order
• D. The wipers must operate quietly

Answer: (C)

For maintaining bus windshield wipers, ensuring that they are clean and in good working order is crucial for several reasons. Clean wipers effectively remove rain, snow, and debris from the windshield, which is vital for ensuring maximum visibility for the driver. Worn or damaged wipers may leave streaks or fail to clear the windshield effectively, posing a safety hazard.

Additionally, wipers that are in good working condition are less likely to break down during operation, which could lead to dangerous situations while driving, especially in adverse weather conditions. Regular inspection and maintenance of the wipers help to extend their life and reliability, ensuring that they function properly every time they are needed.

While the other options mention various aspects of wiper maintenance, such as replacement schedules, coverage, and noise during operation, none encompass the immediate importance of maintaining clarity and functionality, which is essential for safe driving.
