How much following distance should drivers maintain between themselves and the car in front?

Maintaining a following distance of three seconds between your vehicle and the car in front is a widely recognized guideline that promotes safe driving. This distance allows drivers enough time to react to sudden stops or emergencies that may occur ahead. The three-second rule is particularly effective because it accounts for varying speeds and road conditions; for instance, the need for longer distances on wet or slippery roads.

To calculate the three-second rule, you can pick a stationary object, such as a sign or a tree, and once the rear of the vehicle in front passes that object, start counting seconds until your own vehicle reaches it. This method helps ensure that you are keeping a safe distance, which can help prevent rear-end collisions. This rule is also fundamental for maintaining a calm driving environment, allowing for smoother traffic flow and reducing the likelihood of road rage incidents.

Keeping less than three seconds can lead to tailgating, increasing the risk of accidents, especially in areas with frequent stops and starts. Hence, the three-second rule is widely endorsed for defensive driving practices.
