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.

A traffic control element comprising a molded, plastic, hollow element having a preselected configuration and a molded, plastic bse element adapted to be readily assembled and separated from the hollow element, the hollow element being mounted to the base element when it is arranged in a vertical traffic controlling position, the base element being adapted to store ballast means thereon for stabilizing the hollow element when the hollow element is arranged in said vertical position, the improvement comprising the base element having outwardly extending skid means integrally constructed therewith along one side thereof for permitting the assembled traffic control element to be slid across a surface on the skid means when the skid means are positioned into engagement with a surface and so defined to prevent the hollow element and the base element to become unintentionally separated during the sliding on the skid means.
