A crash barrier system includes upper posts, box beams, upper tube profiles and barrier rails. The box beams are connected to the upper posts on a front side of the crash barrier system. The upper tube profiles are connected to the box beams. The barrier rails are fastened to the upper tube profiles. The upper posts are arranged axially parallel to one another at a uniform axial post spacing along the box beams. The upper tube profiles are arranged axially parallel to one another at a uniform axial tube spacing along the box beams. The post spacing differs from the tube spacing.
