What is an important aspect of maintaining visibility while driving?

Maintaining visibility while driving is crucial for safety, and keeping the windows clean is an essential aspect of this. Clean windows allow for clear visibility of the road, other vehicles, and any potential hazards. Dirt, grime, or smudges on the glass can significantly obstruct a driver's view, making it difficult to judge distances or spot dangers.

In contrast, while using daytime running lights, checking wing mirrors, or wearing sunglasses can contribute to visibility in certain situations, they do not address the basic necessity of having clear glass surfaces for optimal visibility. Thus, ensuring that windows are clean serves as a fundamental practice for promoting safe driving conditions.
