What is the recommended following distance behind another vehicle?

The recommended following distance behind another vehicle is at least two seconds. This guideline helps ensure that you have enough time to react to sudden stops or emergencies by providing a buffer zone that can accommodate the speed of travel and the stopping distance needed. The two-second rule allows a driver to gauge their distance from the vehicle ahead, as you should begin to count when the rear of the vehicle in front passes a fixed object, such as a roadside sign or a tree. If you reach that object before you finish counting to two, it indicates that you are following too closely and should increase your distance.

This two-second rule is particularly important in adverse weather conditions, where stopping distances can be significantly longer due to rain, snow, or icy roads. Establishing this safe following distance also reduces the risk of a rear-end collision, giving you time to assess and respond to any sudden changes in traffic.
