Abstract
The present invention is directed to a collapsible road barrier which includes at least one horizontal reflective member which is attached to the upper portion of four supporting legs. The four supporting legs are positioned in pairs with the upper portion thereof hinged together and the lower portion thereof spaced from each other so as to provide support for the horizontal reflective member. The collapsible road barrier also includes a universally collapsible bunk positioned adjacent the lower ends of the supporting legs. The universally collapsible bunk is generally rectangular in shape with each of the four corners of the bunk being attached to one of the supporting legs to provide a surface upon which material such as ballast may be positioned. The collapsible road barrier is readily folded to provide for convenient storage.
