What should you do to maintain visibility while driving?

Maintaining visibility while driving is critical for safe operation of a vehicle, as it allows a driver to be aware of their surroundings and react appropriately to potential hazards. Looking down the road, to the sides, and behind your vehicle offers a comprehensive view of your environment.

By gazing ahead, you can anticipate any potential obstacles or changes in traffic. Observing the sides helps in identifying pedestrians, cyclists, and vehicles that may not be immediately in your line of sight but could still impact your driving. Checking behind ensures awareness of following traffic and provides insight before making maneuvers such as lane changes or merges.

The other choices, while they may address aspects of driving, do not encompass the complete approach required for maintaining visibility. For example, focusing solely on the road ahead limits awareness of lateral or rear threats. Keeping your eyes glued to the rearview mirror also restricts your field of view and may cause you to miss important developments around you. Driving at a slower speed can enhance safety but does not inherently improve visibility; it merely provides more time to react to issues already within your line of sight. Therefore, option B provides the most effective strategy for maintaining comprehensive visibility while driving.
