What precaution should be taken when driving in fog?

Using low beam headlights is the correct approach when driving in fog because they provide better illumination of the road without causing the light to reflect off the fog, which can create a glare that obscures visibility. High beam headlights tend to reflect off the moisture in the fog, causing a blinding effect that reduces how much you can see. By utilizing low beam headlights, drivers can enhance their ability to see the roadway and any obstacles while maintaining a safer environment for themselves and others on the road.

Driving at the speed limit may not be appropriate in foggy conditions since the speed limit is set for clear conditions. In fog, reduced visibility typically requires slower speeds to ensure safety. Keeping windows closed doesn’t specifically address fog visibility and may be less relevant than adjusting your headlights. Therefore, using low beam headlights allows for a more secure and perceptive driving experience during such weather conditions.
