What does tailgating refer to in driving?

Tailgating refers to the practice of following another vehicle too closely on the road. This behavior can significantly increase the risk of a collision, especially if the vehicle in front has to brake suddenly. Maintaining a safe following distance is crucial for allowing sufficient time to react to unexpected changes in traffic conditions. It is recommended that drivers keep at least a two-second gap behind the vehicle ahead, varying this distance based on speed and road conditions.

In contrast, the other options cover different types of driving behavior. Driving in the wrong lane pertains to not adhering to designated traffic flows, which can lead to dangerous situations. Changing lanes without signaling is also unsafe, as it does not inform other drivers of your intentions, potentially causing confusion. Driving under the speed limit may be legal but can still be problematic if it disrupts the flow of traffic. Understanding the concept of tailgating emphasizes the importance of safety and awareness on the road.
