When driving in fog, what lights should you use?

Using low beam headlights in foggy conditions is essential for maintaining visibility and safety. High beam headlights can reflect off the fog, rain, or snow, causing glare and making it harder to see. This can diminish your ability to perceive road conditions and potential hazards ahead.

Low beam headlights, on the other hand, provide a focused beam of light that illuminates the road directly in front of you, reducing glare and enhancing your ability to see and be seen by other drivers. They help cut through the fog while minimizing the amount of light that reflects back, which is crucial for safe driving in these conditions.

Parking lights are not sufficient for driving in fog as they are not designed to illuminate the road effectively and are meant primarily for parked vehicles to increase visibility. Similarly, not using any lights at all in fog is extremely dangerous, as it severely limits your visibility and increases the risk of collision. Thus, low beam headlights are the proper choice for navigating safely through fog.
