How can drivers improve their visibility in foggy conditions?

Using low-beam headlights in foggy conditions is the most effective approach to enhance visibility. High-beam headlights can actually worsen visibility in fog because the light reflects off the water droplets in the fog, creating a glare that can obscure the driver's view. Keeping headlights off completely is not safe, as it eliminates any light source, significantly hampering the driver's ability to see the road and be seen by others. Driving with emergency lights on is also not advisable, as it can confuse other drivers and is not intended for regular driving conditions; it’s primarily meant to indicate a vehicle that is stopped or in need of assistance. Therefore, low-beam headlights are specifically designed to provide sufficient illumination without causing glare, helping drivers navigate safely through fog.
