1. A portable traffic control sign, comprising:
a stand capable of resting on a support surface; at least one mast portion extending upwardly from the stand, the at least one mast portion having a bottom and a top, a substantially hollow interior and an outside diameter of less than approximately 1.75 inches, the bottom of the at least one mast portion being slidingly associated with the stand with no mechanical connection so that the at least one mast portion is freely separable from the stand; at least one sign panel having front and rear surfaces, the at least one sign panel connected to the at least one mast portion so that the front surface of the at least one sign panel faces away from the at least one mast portion and the rear surface of the at least one sign panel faces towards the at least one mast portion; a separate reinforcing member fixedly disposed in the hollow interior of each at least one mast portion such that the reinforcing member remains with the mast portion when the same is removed from the stand, the reinforcing member positioned so as to reinforce the at least one mast portion against a motor vehicle impact in the area of the at least one mast portion reinforced by the reinforcing member; and wherein the at least one sign panel is connected to the at least one mast portion at a single location only, and is positioned at a distance from the at least one mast portion, and wherein further a spacer is positioned between the at least one sign panel and the at least one mast portion at the single location where they are connected, the dimensions of the spacer being such that, along the upwardly extending length of the at least one mast portion, the majority of the rear surface of the at least one sign panel is not in contact with either the spacer or the at least one mast portion. |
