When driving into fog, which headlights should you use?

Use your high-beam headlights.
Use your low-beam headlights.
Use your parking lights.
Use your turn signals only.

The correct answer is: Use your low-beam headlights.

Using low-beam headlights when driving in fog is the correct choice because they are designed to provide adequate visibility without causing significant glare that can reflect off the fog or rain. High-beam headlights produce a bright light that can bounce off dense fog or mist, creating a blinding glare that reduces visibility for both the driver and any oncoming vehicles. Low-beam headlights, however, cast light downward and forward, illuminating the road directly in front while minimizing reflection off the fog particles. This helps the driver see the road and any obstacles better, enhancing safety while navigating through foggy conditions. The other options are not effective for visibility in fog. Parking lights do not provide enough illumination for driving, as they are primarily meant for indicating a parked vehicle’s presence. Using turn signals only would not help illuminate the roadway and could also be confusing to other drivers regarding your intentions on the road.
