Question: 1 / 400

When driving in fog, you should use which of the following?

High-beam headlights.

Low-beam headlights.

Using low-beam headlights when driving in fog is important for visibility and safety. Low-beam headlights illuminate the road directly in front of you and reduce the amount of light that reflects back from the fog, rain, or snow. This reflection can create glare, making it difficult for drivers to see ahead.

High-beam headlights are not suitable in foggy conditions because they project light further down the road but can create a bright reflection off the fog, resulting in impaired visibility. Parking lights are not bright enough to provide proper illumination for driving, and emergency flashers are intended for signaling to others that your vehicle is stopped or in distress, not for improving visibility while driving.
