What action should you take when driving in fog?

When driving in fog, using low beam headlights and reducing speed is the safest action to take. Low beam headlights are designed to provide adequate visibility while minimizing glare. High beam headlights can reflect off the fog, creating a blinding effect that actually reduces visibility further.

Additionally, reducing speed is crucial in foggy conditions because visibility is significantly impaired. Slowing down allows for better reaction time to any obstacles, other vehicles, or hazardous conditions that may not be clearly visible. Being cautious and attentive while driving in fog is essential for ensuring both your safety and the safety of others on the road.
