Question: 1 / 400

When driving in foggy conditions, what type of headlights should you use?

High beam headlights

Low beam headlights

Using low beam headlights in foggy conditions is the best choice because they are designed to reduce the amount of light that reflects off the fog, rain, or mist back at the driver. High beam headlights can create a glare effect, causing more visibility issues in fog since the bright light bounces back at you, making it harder to see. Low beams, on the other hand, illuminate the road directly in front of you without scattering excessive light into the fog, allowing you to see the road and any obstacles more clearly.

Fog lights can be helpful in conjunction with low beams, but they are not designed to replace headlights and may not be sufficient on their own for general driving. Daytime running lights do not provide adequate visibility in fog, as they are not bright enough to cut through dense moisture in the air. Thus, using low beam headlights is essential for safe driving in foggy conditions.
