The technical solution relates to single crash barrier, particularly for high-speed communications borders, comprising vertically arranged poles, on which is fixed via aspacer transverse to the pole by screw connection cross-drain, whereby the cross-drain is made in the shape of hat cross-section, and poles are made of steel profiles of the open C and arranged with the open side faceing the engine forwards, whereby the cross-drain is attached to the poles by means of a screw connection directly. |
