What does it mean if a driver is tailgating?

Tailgating refers to the scenario where a driver follows another vehicle too closely. This behavior is dangerous because it reduces the time and space available for reacting to sudden stops or slowdowns by the vehicle in front. When a driver is tailgating, they may not have sufficient distance to brake safely, which increases the likelihood of a rear-end collision. Maintaining a safe following distance is a key element of defensive driving, allowing for adequate reaction time and minimizing risk on the road. Proper spacing between vehicles can vary based on speed, weather conditions, and road conditions, but the fundamental principle is to ensure that there is enough room to stop safely if necessary.
