When driving in fog, which lights should you use?

• A. High beams
• B. Low beams
• C. Hazard lights
• D. Parking lights

Answer: (B)

Using low beam headlights when driving in fog is essential for maintaining visibility and safety on the road. Fog can significantly reduce visibility, often to less than 100 feet, and high beams can actually exacerbate the problem by reflecting off the fog and creating a glare that obscures your view. Low beam headlights are designed to project light downwards and provide a more focused beam that can illuminate the road directly in front of your vehicle without reflecting off the foggy air. Additionally, low beams help other drivers see your vehicle better without causing discomfort or visibility issues. While hazard lights can be useful when stopped or in situations where you're at risk, they do not provide adequate illumination for driving. Parking lights do not provide sufficient lighting for driving conditions, particularly in fog or low-visibility situations. Therefore, using low beam headlights is the safest and most effective choice when navigating through fog.
