What lights should you use during fog?

During foggy conditions, it is essential to use low beam headlights. This is because low beams provide adequate visibility without causing glare that can reflect off the fog, rain, or snow back into your eyes. High beam headlights tend to illuminate the fog particles, which can create a white wall effect, severely reducing your ability to see ahead.

Low beams are designed to light up the road directly in front of your vehicle while minimizing the amount of light that reflects back towards you, making it easier to navigate through reduced visibility scenarios such as fog.

Parking lights and hazard lights serve different purposes; parking lights are meant to indicate a parked vehicle's presence, while hazard lights signal that there is a problem with your vehicle or that you are driving slowly. Neither is effective for illuminating the road in foggy conditions. Therefore, using low beam headlights ensures safer driving by maximizing visibility and minimizing glare.
