New York Driver License (DMV) Written Practice Test

The recommended following distance behind another vehicle is at least three seconds. This principle is grounded in the need for safety, allowing enough time to react in case the vehicle in front suddenly stops or slows down. The three-second rule enables drivers to maintain a safe distance that can accommodate various driving conditions, including wet or slippery roads, which can significantly increase stopping distances.

By counting three seconds from the moment the vehicle ahead passes a fixed point, such as a sign or a tree, drivers can gauge the appropriate distance to maintain. This time buffer helps to minimize the risk of rear-end collisions, gives a driver sufficient time to react to sudden changes in traffic conditions, and enhances overall road safety. This practice is especially important in heavy traffic or adverse weather conditions, where extra reaction time is crucial.

Maintaining a longer following distance, as suggested by the three-second rule, is a fundamental defensive driving technique that contributes to safer driving habits.
