In foggy conditions, what lighting should you use?

Answer: B — Low beam headlights

In foggy conditions, using low beam headlights is recommended for several important reasons. Fog often reflects light, which can cause a blinding effect if high beam headlights are used. The high beams may illuminate the fog droplets, making it harder to see the road ahead and increasing the glare, which can be dangerous. Low beam headlights, on the other hand, are designed to provide sufficient illumination without causing excessive reflection from the fog. They light up the road surface better, ensuring that drivers can see the markings and other vehicles. Additionally, using low beams helps you to remain visible to other drivers without contributing to fog glare. This makes them the safer and more effective choice when navigating through foggy conditions.
