Why should windshield wipers be kept in good operating condition?

• A. They improve engine performance.
• B. They prevent windshield cracking.
• C. They keep rain and snow off the windshield.
• D. They help you read signs more clearly at night.

Answer: (C)

Maintaining windshield wipers in good operating condition is about keeping clear visibility through the windshield when rain or snow is present. When the wipers work well, they sweep water and slush away smoothly, preventing streaks and water film that can blur what you’re trying to see ahead. This directly reduces the chance of missing hazards, other vehicles, or traffic signals, making driving safer in wet weather. If wipers are worn or damaged, they can smear or fail to remove precipitation, which worsens visibility and increases crash risk. Keeping them in good shape doesn’t affect engine performance and doesn’t prevent windshield cracking, while their primary benefit is keeping rain and snow off the glass so you can see clearly.
