Question: 1 / 400

How should you drive in heavy fog for safety?

Use high beam headlights and speed up

Use low beam headlights and reduce speed

Driving in heavy fog requires specific precautions to ensure safety. Using low beam headlights is essential because these lights are designed to illuminate the road immediately in front of your vehicle without causing glare that can reflect off the fog. High beam headlights can create a blinding effect as the light reflects off the moisture in the fog, reducing visibility rather than improving it.

Reducing speed is equally important in foggy conditions. Fog can create a significant reduction in visibility, making it difficult to see other vehicles, road signs, and potential hazards. By driving at a slower speed, you have more time to react to any unforeseen situations, ensuring that you can stop safely when necessary.

Both of these strategies—utilizing low beam headlights and reducing speed—help maintain control of the vehicle and improve your overall safety while driving in challenging weather conditions like heavy fog.
