What is the best course of action when heavy fog occurs while driving?

• A. Proceed slowly and use high beams
• B. Park at a rest area or truck stop until it has lifted
• C. Turn around and take a different route
• D. Continue driving with caution

Answer: (B)

Heavy fog drastically reduces how far you can see, making it hard to detect other vehicles, road signs, or hazards in time. The safest move is to stop in a safe location and wait for the fog to lift. Parking at a rest area or truck stop provides a designated, low-risk spot away from through traffic where you can pause until conditions improve. This approach lowers the chance of a collision from unseen obstacles. Using high beams in fog makes the glare worse and doesn’t improve your visibility, so they should be avoided. Continuing to drive, even with caution, keeps you in a high-risk situation, and turning around or taking another route may not be safer if you can’t see clearly ahead. Waiting out the fog in a safe spot is the prudent choice.
