What level of beam should you use in fog?
Answer: B — Low headlight beams
In foggy conditions, high beams will create a glare that can reduce visibility even further. Hazard lights are meant for emergency situations, not for driving through fog. Using no lights at all would make it difficult for other drivers to see your vehicle. Using low headlight beams is the safest option in fog as it provides enough light to see the road without creating excessive glare.
