Why should low-beam headlights be used in fog?

Low-beam headlights should be used in fog primarily because they reduce glare and improve visibility. When driving in foggy conditions, using high-beam headlights can actually create more issues. The light from high beams reflects off the fog, rain, or snow, creating a bright, blinding glare that can obscure your vision and make it difficult to see the road ahead. Low-beam headlights, on the other hand, shine at a downward angle which helps to illuminate the road directly in front of the vehicle without bouncing too much light back from the fog. This allows drivers to see better and increases overall safety by enhancing visibility in challenging weather conditions. Using low beams is essential for traveling safely in fog, as it enables a clearer view of the immediate environment, allowing you to navigate effectively.
