What does it mean to "tailgate" another vehicle?

Tailgating refers to the practice of driving too closely behind another vehicle, which increases the risk of a collision. When a driver tailgates, they reduce the time they have to react if the vehicle in front suddenly slows down or stops. This behavior is particularly dangerous because it can lead to rear-end accidents, which are some of the most common types of collisions. Maintaining a safe following distance, usually measured by the "three-second rule," is crucial for allowing adequate reaction time in various driving situations. Being aware of the potential hazards associated with tailgating can help drivers avoid dangerous scenarios on the road.
