ABSTRACT:
A terrorist vehicle arresting system includes a rigid immovable crash barrier positioned at one side of a driveway and a turnstile having a circular sector positioned at the other side of the driveway in such a manner that upon entrance of an unauthorized vehicle through a corresponding gate across the entrance of the driveway, means are provided to rotate the turnstile such that the turnstile deflects the vehicle into the crash barrier. In a further embodiment, two opposing turnstiles are used to wedge an oncoming vehicle therebetween. In one embodiment, the terrorist vehicle arresting system includes a rope-barrier attached to an elevating and lowering mechanism on one side of the driveway and is attached at its other end to the turnstile, such that upon the unauthorized attempted entrance and the striking of the rope-barrier, the turnstile is rotated by the rope-barrier into the driveway, diverting the vehicle into the crash-barrier.
