The main idea is that a traffic barrier is a safety device on roadways designed to protect responders and crash victims by absorbing some of the crash energy. The best choice describes a barrier that can absorb the impact of a secondary crash to shield rescuers, such as a fire truck arriving on scene. Absorbing energy helps reduce the forces on vehicles and people, and it can redirect or slow down traffic to prevent additional injuries. The other options don’t fit because directing pedestrian traffic isn’t the primary role of a roadway barrier, a barrier that cannot absorb impact wouldn’t provide protection in a crash, and a reflective cone is a simple traffic control device rather than a crash-absorbing barrier.
