When driving in fog, which lights should you use?

Answer: B — Low beam headlights

When driving in fog, low beam headlights are the appropriate choice because they illuminate the road without causing glare, which can reflect off the fog and impair visibility. High beam headlights can create a wall of light that bounces back at you in foggy conditions, exacerbating visibility issues rather than improving them. Hazard lights are typically used to indicate that a vehicle is stopped or experiencing issues and do not help improve your visibility to others. Parking lights are not suitable for driving conditions and do not provide adequate illumination for safe navigation in fog. Therefore, using low beam headlights ensures you can see the road clearly while also being visible to other drivers.
