What is the 'two-second rule'?

The 'two-second rule' serves as a guideline for drivers to maintain a safe following distance from the vehicle in front of them. This rule suggests that a driver should choose a fixed point on the road, like a sign or a tree, and as the vehicle in front passes that point, the driver should be able to count at least two seconds before they reach the same point. This interval provides a reasonable buffer time that allows for adequate reaction to sudden stops or emergencies, thereby reducing the likelihood of rear-end collisions.

This method is crucial in promoting safe driving practices, especially under varying conditions such as heavy traffic or adverse weather, where stopping distances may increase. In contrast, increasing speed, measuring stopping distance, or techniques related to lane changes do not directly address the importance of maintaining a safe space between vehicles, which is the fundamental purpose of the two-second rule.
