What type of headlights should be used when driving in fog?

Using low-beam headlights when driving in fog is the best choice because they provide adequate illumination without causing excessive glare. Fog tends to reflect light, and high-beam headlights can actually worsen visibility by bouncing light off the fog droplets and creating a blinding effect. Low-beams, on the other hand, shine the light closer to the road and minimize the reflection, allowing you to see better in these conditions.

While fog lights are specifically designed for such weather conditions, they are usually used in combination with low-beam headlights to enhance visibility near the ground. Parking lights are not sufficient for driving in fog as they do not provide enough illumination. Hence, low-beam headlights are the most effective and safest option for navigating through foggy environments.
