When driving in fog, what should the driver do?

Fog creates low visibility conditions that can significantly impair a driver's ability to see and react to surrounding traffic. When driving in fog, it is essential to take certain precautions to ensure safety.

Reducing speed is crucial because it allows more time to respond to unexpected situations, such as encountering obstacles or other vehicles. The slower a driver goes, the more control they have, and the easier it is to stop if necessary.

Using low beam headlights is particularly important in foggy conditions. High beam headlights can reflect off the fog and create a glare, which can worsen visibility rather than improve it. Low beams provide adequate illumination without causing excessive reflection, allowing the driver to see the road better.

Increasing the following distance is also a vital strategy. When visibility is poor, the stopping distance increases, and maintaining a greater distance between vehicles can help prevent rear-end collisions. This extra space gives drivers more time to react should the vehicle in front of them suddenly brake or make a movement.

All these actions—slowing down, using low beam headlights, and increasing following distance—work together to enhance safety when driving in fog. Therefore, selecting all of these actions as the correct approach is the best choice in light of the situation.
