Which statement about the three-second rule is supported by traffic safety guidance?

Explanation:
The three-second rule is a way to gauge your following distance by time, not by a specific gap. Keeping at least three seconds behind the vehicle ahead gives you a buffer to react and stop if that vehicle suddenly slows or stops, which helps prevent rear-end crashes. That’s why the statement about it helping maintain a safe following distance is the best choice. It doesn’t promote tailgating, isn’t about pedestrians, and isn’t optional in dry weather—it's a safety baseline, with more time needed in wet or slick conditions.
