What actions should you take when driving in foggy conditions?

When driving in foggy conditions, using low beam headlights and reducing speed is crucial for safety. Low beam headlights are designed to provide adequate visibility without reflecting excessive light off the fog, which could create glare and further reduce your ability to see. This helps you see the road and any obstacles more clearly.

Reducing your speed is equally important in foggy conditions, as visibility is significantly compromised. Slower speeds give you more time to react to any unexpected situations, such as sudden stops or obstacles in the road. It also allows for a safer following distance behind other vehicles, helping to prevent collisions.

In contrast, using high beam headlights can create a blinding effect when the light reflects off the fog, hindering visibility. Speeding up to maintain flow could lead to dangerous situations, as others may not be able to see you well. Lastly, following the car ahead closely is risky; if the lead car encounters an obstacle, you may not have enough time to react safely. Therefore, adjusting your driving habits to be more cautious, as indicated in the correct answer, is essential for navigating fog safely.
