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

Using low beam headlights in foggy conditions is the best practice because they provide adequate illumination of the road without causing glare. High beam headlights can reflect off the fog, rain, or snow and create a blinding effect, which decreases visibility further. Low beams cast light closer to the ground and help illuminate the road ahead without reflecting excessively off the moisture in the air.

Fog lights are also designed specifically to improve visibility in fog by emitting a wide, low-angle beam of light. However, using them exclusively may not be sufficient in all foggy conditions, especially if visibility is severely diminished. Relying solely on parking lights is also not advisable since they do not provide illumination for driving, making it difficult to see and be seen by other drivers. Therefore, employing low beam headlights optimizes visibility and safety during foggy driving conditions.
