When driving in heavy fog, what should you do to increase your visibility?

  1. Drive in the center lane

  2. Use the passing lane

  3. Turn on your high beams

  4. Reduce your speed

The correct answer is: Reduce your speed

When driving in heavy fog, it is important to reduce your speed in order to increase your visibility. Driving at high speeds can decrease your reaction time and make it difficult to see hazards on the road. Using the passing lane or driving in the center lane may not always be the safest option, as these lanes are typically used for passing or emergency vehicles. Additionally, it is not recommended to use your high beams in heavy fog, as they can reflect off the fog and make it even harder to see. Therefore, the best course of action is to slow down and use caution while driving in heavy fog.
