In adverse conditions, such as rain or snow, what is the recommended following distance compared to normal conditions?

• A. Maintain a 1–2 second gap at all times.
• B. Keep a 4–6 second gap in rain, snow, or low visibility and when following large vehicles.
• C. Always maintain a 8–10 second gap regardless of conditions.
• D. Follow as closely as possible to avoid getting stuck behind slow drivers.

Answer: (B)

In adverse conditions, you need more following distance because reduced traction and poorer visibility slow your ability to react and stop. The recommended gap is 4–6 seconds when it’s raining, snowing, or visibility is low, and when you’re following large vehicles. This extra space is necessary because stopping distances lengthen on slick surfaces and drivers may brake earlier or more abruptly than you expect. A practical way to gauge it is to pick a fixed object ahead and count seconds from when the vehicle in front passes it to when you pass it. If you can’t reach four seconds, you’re too close; push toward six seconds in heavy rain, snow, or behind big trucks. In normal dry conditions, a shorter, about 2-second gap is typical, so you’re deliberately increasing distance to match the safer, slower conditions.
