How Roller Barriers Change Road Safety

Roller barriers are one of the most innovative road safety devices in modern highway engineering. In this video, we explain how roller barriers work, how they manage energy during a collision, and why they reduce the severity of crashes compared to traditional rigid guardrails. By absorbing and redirecting impact force through rotating elements, roller barriers help keep vehicles on the roadway and reduce secondary collisions. These systems represent a shift in safety thinking — from simply stopping vehicles to managing crash energy more intelligently.
