When driving in fog, what lights should you use?

Using low beam headlights when driving in fog is important for several reasons. Fog can create a thick barrier of moisture in the air, which can scatter light from your headlights. High beam headlights are generally not effective in fog because the light can reflect back into your eyes, reducing visibility rather than increasing it. This can create a blinding effect, making it even harder to see the road ahead.

Low beam headlights are designed to provide a wider and more controlled beam of light closer to the ground, which helps illuminate the road without causing too much glare. They also minimize the chances of the light bouncing back at you, thus allowing for better visibility through the fog. Fog lights can be used in conjunction with low beams, specifically designed to illuminate the road directly in front of your vehicle without scattering too much light.

Therefore, using low beam headlights is the most effective choice for safe driving conditions in fog, as it optimizes visibility while minimizing light glare.
