The modular vehicle anti-intrusion barrier, consists of entry (13) and stop (2) barriers, connected by a lever, slider and lock mechanism. An authorised vehicle can be allowed to pass by lifting a plate (9) by a lever (11) and rotating a second lever (14) to lower the entry barrier (13) into a horizontal position. - An unauthorised vehicle however, pressing against the entry barrier, a second plate (16) to press against the first plate (9), and the slider to release the lock (7). The stop barrier (2) is then raised automatically by its spring (5), preventing the unauthorised vehicle from passing.
