ABSTRACT:
A traffic barricade of the A-frame type constructed of a lightweight material such as plastic to have a forbidding appearance. The barricade members are unitarily constructed to be interchangeable and with integral hinge mechanisms. The hinge mechanisms have detenting elements for improving the resistance to winds tending to cause the closure of the "A" stance of the barricade. The barricade permits a damaged hinge element to be readily replaced. Ballast may be added to a storage compartment arranged adjacent the supporting surface for the barricade. The design of the plastic barricade permits a warning light to be directly secured by a mounting bolt functioning as a hinge pin. The individual barricade members may be stacked with substantially no relative movement of the stacked members.
