What does the "two-second rule" refer to in driving?

The "two-second rule" refers to a method of maintaining a safe following distance while driving. This rule helps to ensure that drivers have enough time to react if the vehicle in front of them suddenly stops or slows down. To use the two-second rule, a driver should choose a fixed point on the road, such as a sign or a tree, and start counting when the rear of the vehicle in front of them passes that point. If the driver reaches the same point before they finish counting to two seconds, they are following too closely and should increase their distance from the vehicle ahead.

This approach is especially important in inclement weather or in situations where road conditions may require more time for stopping, thereby enhancing overall safety on the road. Proper following distance helps prevent collisions and allows for safer driving, contributing to a more secure driving environment for everyone.
