What should you do if fog closes in completely while you are driving and visibility is reduced to near zero?

• A. Carefully pull as far off the road as possible, and stop
• B. Accelerate to exit quickly
• C. Use high-beam headlights
• D. Follow the taillights of the car ahead

Answer: (A)

When visibility is nearly zero, the priority is to remove yourself from the unsafe driving lane and wait for the fog to lift. Pulling completely off the road and stopping in a safe spot creates distance from other vehicles and gives you time to reassess once visibility improves. If you stop, use hazard lights to warn others that you’re stationary and keep your lights on so you remain visible. High beams don’t help in fog—the light reflects back and actually reduces your ability to see. Accelerating to “exit quickly” can put you into traffic you can’t see, and following the taillights of the car ahead is risky because you may not be able to see hazards or the other vehicle if visibility is very poor.
