What is the recommended following distance under normal conditions?

• A. At least a 3-second rule between your vehicle and the one ahead; increase in poor or slippery conditions.
• B. One second.
• C. Five seconds.
• D. None; keep speed constant.

Answer: (A)

Maintaining a safe following distance gives you time to notice hazards, react, and brake before you reach the vehicle ahead. Under normal conditions, the best rule is to stay about a three-second gap. Pick a fixed object on the road, and when the vehicle ahead passes it, begin counting seconds; if you reach the object before you finish the count, you’re too close. This spacing reflects typical reaction time and braking distance, giving you a reliable cushion.

In poor or slippery conditions, increase this distance to account for longer stopping distances and reduced traction. A one-second gap is not enough to react and stop safely, while a five-second gap is more than necessary for normal conditions and can slow traffic unnecessarily.
