ABSTRACT:
An apparatus for use as a sign or display, for example as a traffic barricade, includes a base that has a hollow cavity that can be filled with ballast, such as sand or water. A receiver is formed in the base to pivotably receive interchangeable vertical signs having display areas with instructions or attention grabbing indicia. The base and vertical sign also cooperate to hold the sign vertical until overcome by a certain amount and direction of force, at which time the sign pivots down to prevent breakage of the apparatus. It can be easily replaced to its original position. The base also cooperates with other removeable items such as a barrel type device which would matably fit around the perimeter of the base. The base is disassemblable from the sign or barrel for handling and storage.
