Which statement about driving in poor visibility is correct?

• A. Increase your following distance
• B. Keep your distance the same
• C. Speed up to clear visibility
• D. Stop in the roadway until visibility improves

Answer: (A)

In poor visibility your ability to see hazards and your stopping distance are both reduced, so you need more time to react. Increasing the following distance gives you extra space to notice a problem and start braking gradually, which greatly lowers the risk of a rear-end collision. Keeping the same distance or speeding up doesn’t buy you that extra time and can leave you with not enough distance to stop safely. Stopping in the roadway until visibility improves creates a dangerous obstacle for others and is not a safe or legal option. In fog or heavy rain, aim for a larger gap—think several seconds instead of just a quick glance—so you have ample time to react as conditions worsen.
