Under wet or low visibility conditions, how should your following distance change relative to the two-second rule?

• A. Maintain exactly two seconds.
• B. Decrease to one second.
• C. Do not follow the two-second rule during rain.
• D. Increase beyond the two-second rule.

Answer: (D)

In wet or low-visibility conditions, your following distance must be increased beyond the two-second rule. The two-second rule is a safe baseline for dry roads, but rain and limited visibility extend both braking distances and the time you have to react to hazards. Wet pavement reduces traction, making it harder to stop quickly, and spray or poor visibility can hide dangers ahead. Giving yourself more than two seconds of gap creates a safety buffer, allowing you to react and brake gradually without forcing a sudden stop that could lead to a collision. In light rain, aim for a bit more than two seconds; in heavier rain or worse visibility, push toward three to four seconds or more, especially at higher speeds or on hills. The other options imply keeping the same distance or reducing it, which doesn’t account for the increased risk in these conditions.
