When driving in fog, what actions should you take?

Using low beam headlights and reducing your speed while driving in fog is the correct approach for several crucial reasons.

Low beam headlights are designed to illuminate the road directly in front of you without causing glare that can reflect off the moisture in the air during foggy conditions. This glare can worsen visibility rather than improve it, making it much harder to see the road and other vehicles. In contrast, high beam headlights can reflect off the fog, creating a wall of light that can further reduce your ability to see.

Reducing your speed is equally important because fog severely limits visibility. By slowing down, you allow yourself more time to react to potential hazards, such as other vehicles, animals, or obstacles that may suddenly appear. Driving at a reduced speed also helps ensure that you maintain control of the vehicle when faced with sudden changes in the road or traffic conditions.

In foggy conditions, maintaining awareness of your surroundings and adjusting your driving behavior is key to safety, which makes this strategy of using low beam headlights and reducing speed the most effective method for navigating through fog.
