What should you do when driving in fog?

Answer: B — Use low beam headlights and decrease your speed

When driving in fog, using low beam headlights and decreasing your speed is the best practice. Low beam headlights are designed to illuminate the road directly in front of your vehicle without causing glare that can reflect off the fog, which improves visibility. On the other hand, high beam headlights can scatter light in foggy conditions, making it more difficult to see and potentially blinding you due to the light reflecting back. Additionally, decreasing your speed is crucial in foggy conditions because visibility is significantly reduced. Slowing down allows you more time to react to any obstacles or changes in the road conditions, enhancing your safety and that of others on the road. Being cautious and attentive while driving in fog can prevent accidents and ensure a safer journey.
