What is the recommended following distance behind another vehicle?

The recommended following distance behind another vehicle is at least three seconds. This guideline is based on ensuring that drivers maintain enough space to react appropriately to sudden stops or emergencies in front of them. By keeping at least a three-second gap, a driver has ample time to assess the situation, anticipate changes, and safely respond, particularly in varying road conditions or adverse weather scenarios.

This distance can be measured by selecting a fixed object along the road, like a sign or tree; when the vehicle in front passes that object, you should be able to count to three before your own vehicle reaches the same object. This practice enhances safety by allowing for adequate response time and reducing the chances of collisions, which may occur if following too closely.

While other options suggest shorter distances, they do not account for the necessary reaction time required for safe driving, especially in heavier traffic or inclement weather. Thus, adhering to the three-second rule is a critical component of defensive driving and maintaining safe driving practices.
