How can worn out wiper blades affect driver visibility?

Worn out wiper blades can significantly impact driver visibility primarily by leading to streaking on the windshield. When wiper blades are worn, they become less effective at clearing rain, snow, or debris from the glass. Instead of providing a clear view, they may leave behind streaks or areas of obscured visibility. This reduced clarity can be particularly dangerous in inclement weather, as it may limit a driver’s ability to see other vehicles, pedestrians, road signs, and obstacles ahead, thereby increasing the risk of accidents.

The other options do not relate to the functionality of wiper blades. Dimmed lights, engine temperature, and fuel consumption are issues associated with different vehicle components and do not have a direct connection to how wiper blades affect visibility. This emphasizes the importance of maintaining wiper blades in good condition to ensure safe driving and optimal visibility in all weather conditions.
