Which vehicle condition can lead to reduced visibility?

Reduced visibility while driving can significantly increase the risk of accidents, making it crucial to maintain clear sight lines. Dirt or debris on headlights is a primary factor that can obstruct light output, reducing the effectiveness of the vehicle’s headlights in illuminating the road ahead, especially at night or in poor weather conditions. When headlights are obscured, they may not project sufficient light, making it difficult for the driver to see obstacles, road signs, and pedestrians. Maintaining clean headlights is therefore essential for safe driving, which is why this condition directly leads to reduced visibility.

In contrast, clean windows, proper tire pressure, and fully functional windshield wipers enhance visibility and driving safety. Clean windows allow for an unobstructed view of the road, proper tire pressure ensures optimal traction and handling, and functional wipers ensure that rain or debris on the windshield is effectively cleared, all contributing to a safer driving experience.
