What is the appropriate response if visibility is severely limited while driving?

When visibility is severely limited while driving, the most appropriate response is to use headlights and drive cautiously. This action is essential because headlights improve your ability to see the road ahead and allow other drivers to see you, significantly enhancing safety when navigating in low-visibility conditions. Driving cautiously means reducing speed and being more alert to your surroundings, allowing you to react effectively to any unexpected obstacles or changes in traffic.

Maintaining a slower speed helps ensure that you have sufficient time to stop or maneuver safely if necessary. This approach minimizes the risk of accidents, especially in environments like airside operations, where precision and safety are crucial.

In contrast, attempting to speed up or ignoring the conditions can lead to severe safety hazards, while relying on other vehicles invites unnecessary risk, as those drivers may not be making safe decisions themselves. Therefore, using headlights while driving cautiously is the best practice to maintain safety in low-visibility situations.
