What does it mean if a vehicle is ‘tailgating’ another?

Tailgating refers to the act of driving too closely behind another vehicle. This practice is unsafe as it decreases the driver's reaction time in the event of sudden stops or emergencies. When a driver is tailgating, they do not provide adequate space between their vehicle and the one in front, which can lead to rear-end collisions if the lead vehicle has to brake unexpectedly. Therefore, maintaining a safe following distance is crucial for road safety and to avoid accidents.

The other options describe different driving behaviors that do not pertain to tailgating, focusing instead on lateral movement, speed, and lane changes. Understanding the concept of tailgating emphasizes the importance of safe driving practices and awareness of following distances on the road.
