On a dry road, what is the recommended following distance?

The recommended following distance on a dry road is at least 4 seconds. This 4-second rule allows for enough time to respond to sudden changes in traffic or emergencies, giving drivers the necessary space to react effectively without risking a collision. It takes into account a comfort zone that balances the need for safety with the reality of typical driving speeds and conditions.

Following too closely, or tailgating, reduces a driver's ability to react to the actions of the vehicle in front and can lead to rear-end collisions. The 4-second following distance is a good practice because it helps ensure that a driver has ample time to brake or maneuver if the vehicle ahead suddenly slows down or stops.

In adverse weather conditions or when driving larger vehicles, increasing the following distance is advisable, but under normal dry conditions, 4 seconds provides a solid guideline for safe driving.
