ABSTRACT:
A plastic barricade includes improved hinges which can be freely opened to an almost flat position so that no unwanted forces cause breakage of the hinges. Limiting bolts are placed in recesses on each face of the barricade so that the bolts in the normal active position will limit the opening or unfolding of the frame units of the barricade to, for example, 40.degree., but when closed will still present a planar surface with the bolt heads being recessed so that stacking of one barricade on the other will not be interfered with. In addition, a slot is cut in the middle panel member to allow insertion of a road warning sign and horizontal support platform for warning lights is also provided.
