What is the “two-second” rule?

The “two-second” rule is an essential guideline for drivers to maintain a safe following distance behind the vehicle in front of them. It is based on the principle that a driver should stay far enough back to have adequate reaction time to prevent a collision in case the vehicle ahead suddenly stops or slows.

To apply this rule, a driver should select a fixed point on the road, such as a sign or a tree. When the vehicle in front passes that point, the driver should be able to count at least two seconds before reaching the same point. This timing helps ensure that there is enough space to stop safely if necessary.

Maintaining this distance is especially important in adverse conditions, such as rain or fog, where stopping distances increase. The two-second rule contributes to overall road safety by promoting proper spacing between vehicles, reducing the risk of tailgating, and allowing drivers time to react in emergencies.
