ABSTRACT:
A collapsible warning barricade apparatus for restricting access to a designated area by vehicular and pedestrian traffic in which at least an upstanding portion of the apparatus is capable of collapsing towards a substantially ground surface-hugging position upon impact from traffic, as well as capable of collapsing into a substantially flat position for transportaion and/or storage. The barricade is restrained in its substantially upright position by two support runners which are pivotally attached to the barricade member. At each pivot point, automatic locking and biasing apparatus allow the barricade member to rotate from a locked upright position upon impact to a locked ground surface-hugging position. The support runners of the barricade may additionally be provided with spurs along the top edge to affix a sandbag, when required for ballast. A variety of signalling indicia are further integrated into the barricade member for warning emphasis.
