When driving in fog, what type of headlights should be used?

Using low beam headlights in fog is essential because they are designed to illuminate the road directly in front of you without reflecting too much light back at the driver. Fog creates a thick, dense area of moisture that can scatter light from high beams, causing glare and making it difficult to see. Low beams provide better visibility in these conditions because they direct light downwards and reduce the amount of light that bounces off the fog, allowing a clearer path ahead. This helps to maintain visibility for both the driver and other vehicles on the road, ensuring safer driving conditions.
