Which lighting configuration is recommended in foggy conditions?

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

Answer: (A)

In foggy conditions you want lighting that keeps illumination close to the road and reduces glare for others. Low beam headlights, or dedicated fog lights if your vehicle has them, accomplish this by lighting the roadway just in front of you and to the sides, which helps you see lane markers and obstacles while making you more visible to other drivers.

High beams shine light farther ahead, but that light bounces back off the fog and creates a bright glare that actually reduces visibility. Hazard lights are meant to signal trouble or a stopped vehicle, not to illuminate the road while driving, which can confuse other drivers. Parking lights are too dim to help you see and aren’t appropriate for driving in fog.
