What should be your minimum following distance when behind another vehicle?

Maintaining a minimum following distance of four seconds behind another vehicle is essential for safe driving. This four-second rule allows you to have adequate space to react to sudden stops or emergencies that the vehicle in front of you may encounter. It provides you with a buffer zone that accounts for varying conditions such as road quality, weather conditions, and the type of vehicle you are driving. For instance, if the road is slick from rain or snow, and if you are driving a larger vehicle that takes longer to stop, having that extra time is crucial for preventing collisions.

In normal driving conditions, it is often recommended to keep a distance of at least two seconds; however, the four-second rule is a more conservative approach that enhances safety in various situations. It is particularly important in heavier traffic, at higher speeds, or when driving in adverse weather conditions, where stopping distances may significantly increase.
