What is a recommended action when driving in foggy conditions?

When driving in foggy conditions, using low beam headlights is crucial for safety. High beam headlights can scatter light in fog, rain, or snow, reflecting it back and creating glare which impairs visibility even further. Low beam headlights, on the other hand, direct light downwards and closer to the ground, which helps illuminate the road directly in front of the vehicle without creating excessive glare.

Maintaining normal speed in fog can be hazardous due to reduced visibility, as it may not allow adequate reaction time for unexpected obstacles. Turning off all lights is also unwise as it could make the vehicle less visible to others on the road. Therefore, using low beam headlights is the recommended action to improve visibility and enhance safety in foggy conditions.
