What is the best advice for driving in heavy fog?

• A. Try not to drive until the fog is lifted
• B. Drive at normal speed with high beams
• C. Use only windshield wipers and continue
• D. Pull over and wait for someone to guide you

Answer: (A)

Heavy fog severely cuts visibility and makes judging speed and distance dangerous. Delaying the trip until the fog lifts removes the main risk, giving you a much safer opportunity to drive only when you can clearly see and react to hazards. High beams actually make visibility worse in fog by increasing glare, driving at normal speed leaves little room for error, and relying on windshield wipers alone won’t restore clear vision. The idea of waiting for someone to guide you isn’t practical or reliable in real driving conditions. If you must travel in fog, slow down well below normal speeds, use low-beam headlights (or fog lights if available), and keep a generous following distance, but postponing the trip is the safest choice.
