What is the recommended distance to keep from the vehicle ahead of you in good driving conditions?

The recommended distance to keep from the vehicle ahead in good driving conditions is based on a time-distance rule rather than simply a physical length. Maintaining a following distance of two seconds allows for a safe buffer that can accommodate changes in speed or sudden stops. This two-second rule ensures that drivers have enough time to react to the actions of the vehicle in front, which is crucial for preventing collisions.

This distance can be adjusted according to various factors such as weather conditions, visibility, and road surface. In adverse conditions, like rain or snow, increasing the following distance beyond two seconds becomes even more important to ensure safety. Relying solely on car lengths may not account for the varying sizes of vehicles or speeds, making it less effective than a time-based measure.
