If fog reduces visibility to near zero, the safest action is to:

• A. Carefully pull off the road and stop
• B. Stop in the travel lane with hazard lights on
• C. Increase speed to exit fog
• D. Continue with high beams

Answer: (A)

When visibility is essentially zero, the safest move is to remove yourself from the flow of traffic and wait until conditions improve. Pulling off the road to a safe spot away from the travel lanes reduces the chances of being struck by other vehicles that you can’t see or anticipate. Once parked, switch on hazard lights to alert other drivers. Continuing in the travel lane or speeding up to push through fog increases the risk of a collision because you have far less time to react to hazards you can’t see. High beams actually make fog worse by reflecting light back at you, further reducing visibility. Stopping off the road gives you a safer position and time to wait for conditions to clear.
