When driving through fog, what type of headlights is best to use?

Using low beams in foggy conditions is essential for maintaining visibility without causing glare. High beams tend to reflect off the fog droplets, which can create a blinding effect and reduce your ability to see the road and other vehicles clearly. Low beams, on the other hand, provide a more focused light that illuminates the road directly in front of you, allowing for better visibility without the reflection interference that high beams cause.

Parking lights and hazard lights serve different purposes and are not suitable for driving in fog. Parking lights are meant to notify other drivers that your vehicle is stationary, and hazard lights indicate a temporary stop for an emergency, neither of which contribute to safe driving in fog. Thus, using low beams is the safest choice to enhance visibility while navigating through foggy conditions.
