What is the importance of the “2-second rule”?

The "2-second rule" is a crucial guideline in defensive driving that helps drivers maintain a safe following distance from the vehicle in front of them. By ensuring that there is at least a 2-second gap between your vehicle and the one ahead, this rule allows a driver sufficient time to react to sudden stops or emergencies.

When a driver observes the vehicle in front pass a fixed point, they should be able to count at least two seconds before their own vehicle passes that same point. If the driver reaches the point in less than two seconds, it indicates that they are following too closely, which increases the risk of a collision.

This rule is particularly important because it accounts for various factors, including the speed of the vehicle, road conditions, and visibility. Maintaining this distance helps ensure there is enough space to brake safely, providing a cushion that can prevent rear-end collisions.
