What is the two-second rule?

The two-second rule is a guideline that emphasizes the importance of maintaining a safe following distance behind the vehicle in front of you. By ensuring that there is at least a two-second gap, drivers provide themselves with enough time to react in case the vehicle ahead suddenly stops or encounters an obstacle. This rule is crucial for preventing rear-end collisions and allows for safe stopping, particularly in varying traffic conditions.

To apply the two-second rule, a driver should pick a stationary object on the side of the road, such as a sign or tree. When the rear end of the vehicle in front of you passes that object, you should begin counting seconds until your own vehicle reaches the same point. If you reach the object before counting to two seconds, it indicates that you are too close and should increase your following distance.

By following this guideline, drivers can significantly enhance their overall reaction time and road safety, making it a key concept in defensive driving.
