When driving in foggy conditions, which lights should you use?

Explanation

In foggy conditions, you should use your low-beam headlights. Do NOT use your high-beam headlights in fog. High beams will reflect off the water droplets in fog and actually make it harder for you to see (causing a bright white glare). Low beams, on the other hand, aim downward toward the road and will improve your visibility in fog. If your vehicle is equipped with fog lights (which are typically low-mounted and emit a wide, low beam), you should use those in addition to your low-beam headlights. They are designed specifically for these conditions. The goal is to cast light on the road and edges of the road without lighting up the fog itself directly in your line of vision. Remember also to slow down in fog, since you can’t see as far ahead. And make sure your headlights are turned on (low beam) even in daytime fog – it helps other drivers see you. Many newer cars have automatic lights, but double-check, because some auto systems don’t turn on in daytime fog. To summarize: use low-beam headlights (and fog lights if you have them) in fog. Avoid high beams. By using the correct lighting, you’ll maximize what you can see and help ensure you’re visible to others without blinding them or yourself.
