Why are rear-end collisions so common on interstate highways?

Rear-end collisions on interstate highways often occur due to tailgating, which is when a driver follows another vehicle too closely. This practice reduces the tailgating driver's ability to react quickly to sudden stops or slowdowns of the vehicle in front. On high-speed roads like interstates, the distance required to stop safely increases, making it vital for drivers to maintain an adequate following distance. When a driver is tailgating, even a minor change in speed from the lead vehicle can result in a collision, as the tailgating driver may not have enough time or space to brake effectively.

While distractions inside the vehicle, driving too fast for conditions, and poor weather can contribute to accidents, tailgating specifically heightens the likelihood of rear-end crashes by not allowing enough reaction time. Therefore, emphasizing the importance of maintaining a safe following distance is essential for preventing these types of incidents on the road.
