If visibility is poor due to fog or heavy rain, which actions should you take?

• A. Speed up to pass through the fog as quickly as possible.
• B. Use high beam headlights and tailgate the vehicle in front.
• C. Slow down, increase following distance, use lights, and avoid sudden maneuvers.
• D. Brake abruptly if you cannot see clearly.

Answer: (C)

When visibility is poor, the safest approach is to slow down, give yourself more following distance, keep lights on, and move smoothly without sudden actions. Slowing helps you react to hazards in time, and a larger gap to the car in front gives you room to stop if visibility suddenly worsens. Turning on your lights makes you more visible to others and helps you see the road ahead; in fog, use low beams so glare doesn’t reflect off the moisture and reduce your own visibility. Avoid sudden maneuvers because quick steering or abrupt braking on wet or foggy pavement can cause skidding or loss of control.

This combination reduces crash risk in fog or heavy rain. Rushing through limited visibility, using high beams, tailgating, or braking abruptly when you can’t see clearly all increase danger and should be avoided. If conditions stay bad, find a safe place to wait until visibility improves.
