In foggy conditions, which beam should you use?

• A. High beams
• B. Low beams
• C. Bright beams
• D. Lower beam

Answer: (B)

In fog, you want to minimize glare and illuminate the road where you actually drive. High beams push light straight ahead and bounce off fog droplets, creating a bright haze that makes it harder to see and can blind other drivers. Low beams are aimed downward toward the road, improving contrast and letting you see lane markings and hazards without reflecting back into your eyes. If your vehicle has fog lights, use them along with the low beams to further light the road beneath the fog. Remember to slow down and increase following distance as conditions worsen.
