Abstract
A portable vehicle barrier for positioning in a roadway or the like has a base plate carrying first and second spaced stanchions forming a checkpoint therebetween. A shaft is pivotally secured to the base plate and extends transversely between the stanchions. A gate or barrier plate is pivotal with the shaft between a first horizontal position and a second angularly disposed position adapted for preventing vehicle passage through the checkpoint by engagement of the barrier plate with the vehicle. An anti-tampering means associated with said stanchions and said gate is provided for preventing unauthorized interference with the raising and lowering of the gate.
