ABSTRACT:
A traffic control device constructed as either a one piece or two piece device of a resilient plastic by molding. Both the one piece and two piece devices are constructed to have a ground engaging surface defined with a multiplicity of dependent elements arranged thereon in a preselected pattern for distributing the weight of any ballast means over the dependent elements so that they function as localized pressure points to more firmly engage the supporting surface to minimize their movement on the supporting surface due to wind gusts, vibrations or the like.
The two piece device is constructed with a base element that not only includes the dependent elements but also skids for permitting the assembled two piece device to be slid over a supporting surface on the skids to prevent the assembled two pieces from becoming unintentionally detached while being slid.
The devices are capable of being stacked with and without the warning light secured thereto and present the appearance of a formidable object.
