In adverse weather, how should you adjust your following distance?

• A. Use a one-second rule
• B. Increase the gap beyond the three-second rule
• C. Maintain exactly a three-second gap
• D. Stop driving until weather improves

Answer: (B)

In adverse weather, you need a larger following distance because stopping distances grow when roads are wet, icy, snowy, or when visibility is reduced. The three-second rule is a good baseline on dry pavement, but rain, snow, or fog make it harder to react and stop in time. So you should extend the gap beyond the three-second rule to give yourself more room to slow gradually and avoid a rear-end crash if the vehicle ahead brakes suddenly. A practical way to apply this is to pick a fixed mark on the road and count seconds as you pass it after the vehicle in front does. If you’re counting four, five, or more seconds, you’re following at a safer distance for those conditions. Slow down as needed and stay alert for changing weather. The other options aren’t as safe: a one-second rule is far too short in wet or slick conditions; maintaining exactly three seconds doesn’t account for reduced traction and visibility; stopping driving unless conditions are so severe they’re impassable isn’t a reasonable or safe standard in most situations.
