- High-Tension Cable Barrier (HTCB) is a flexible barrier system used on roadsides or as a median barrier to reduce the severity of run-off-the-road crashes. It typically consists of three or four cables under high tension supported by breakaway steel posts. When struck, the posts break and the cables flex to absorb the vehicle's kinetic energy and redirect it along the barrier123.Learn more:✕This summary was generated using AI based on multiple online sources.
