What is the two-second rule used for?

The two-second rule is a technique used to determine a safe following distance between your vehicle and the vehicle in front of you. By choosing a fixed point on the road, such as a sign or a tree, you start counting when the vehicle ahead passes that point. If you reach the same point in less than two seconds, you are following too closely and should increase your distance. This method helps ensure that you have enough time to react to stops or emergencies, contributing to overall road safety. The concept emphasizes the importance of maintaining a safe buffer zone, particularly under various driving conditions, such as inclement weather or heavy traffic, where stopping distances may increase.
