What is the advised following distance behind another vehicle in normal conditions?

The advised following distance behind another vehicle in normal conditions is three seconds. This rule of thumb is established to give drivers ample time to react to any sudden stops or changes in traffic. By maintaining a three-second gap, drivers can ensure they have enough space to effectively respond to potential hazards on the road, such as when the vehicle in front of them brakes unexpectedly.

This three-second rule allows for the time needed to evaluate the situation ahead and provides an appropriate buffer to avoid tailgating, which can lead to accidents if the leading vehicle stops suddenly. In adverse conditions, such as rain or snow, extending this following distance is advisable to accommodate longer stopping distances required due to reduced traction.
