Which of the following contributes to reduced visibility while driving?

Reduced visibility while driving is significantly impacted by weather conditions, and rain is a prime example of this. When it rains, water collects on the road surface and can create a reflective layer, making it difficult to see the road clearly. Additionally, rain can cause windshield wipers to work harder, and if not functioning properly or if visibility is further compromised by the water droplets, the driver may struggle to see other vehicles and road signs. The presence of rain also typically reduces overall ambient light, increasing the risk of diminished eyesight, even if the rain is not heavy.

In contrast, clear skies, good lighting, and sunny weather typically enhance visibility by providing ample light and a distraction-free environment. These conditions allow drivers to see further and more clearly, making it easier to navigate safely. Therefore, rain is the only option that typically contributes to reduced visibility while driving.
