The invention relates to a device capable of reliably stopping any vehicle attempting to cross the barrier (2) (arrow 3). Should an emergency button be triggered or the barrier (2) be destroyed, the latch (11) retracts (arrow 20) and the panel (7) falls into the pit (4) by tilting about its axis (5). Simultaneously, the pikes (17) rise above the roadway in the rearward direction. If the vehicle passes over them, its front falls into the pit (4) and in any event it is stopped. The invention is used as a protective system which can be employed even against suicide vehicles loaded with explosives and driven at full speed, particularly for the purpose of carrying out attacks. <IMAGE>
