What is the recommended following distance behind another vehicle?

The recommended following distance behind another vehicle is three seconds under normal conditions. This guideline is based on the principle of maintaining a safe distance that allows sufficient time to react to sudden stops or emergencies. The three-second rule provides drivers with enough space to perceive and respond to the actions of the vehicle in front of them, helping to prevent rear-end collisions.

In practice, this means that when the vehicle in front of you passes a stationary object, such as a sign or a tree, you should count to three before reaching that same object. This counting method helps ensure that you are maintaining a safe distance, allowing for proper reaction time to any potential hazards or changes in traffic.

While under certain conditions or circumstances, like inclement weather or heavy traffic, a longer following distance may be advisable, three seconds is generally deemed appropriate for normal driving conditions to balance safety and traffic flow.
