What should you do when driving in fog?

Answer: B — Use your low beam headlights

When driving in fog, using low beam headlights is recommended because they create a wide, low-reaching beam that helps illuminate the road directly in front of you without reflecting off the fog, rain, or snow back into your eyes. This reduces glare, which can be especially disorienting in foggy conditions and can significantly impair visibility. Low beams allow you to see the road and any obstacles more clearly while also allowing other drivers to see you. Using high beam headlights, on the other hand, can worsen visibility in fog because they tend to reflect off the water droplets in the fog, creating a blinding effect and making it harder to see. Driving without headlights is unsafe in fog since it can render your vehicle invisible to others, increasing the risk of accidents. While slowing down and using hazard lights can be part of a cautious approach, it is critical to have your lights on for visibility, making low beam headlights the best choice.
