ABSTRACT:
A traffic barricade is constructed from a foldable material such as cardboard impregnated with a waterproofing material or double-faced corrugated plastic or cardboard impregnated with a waterprooofing material. First and second flat sheet portions of such material are provided, each having a pair of scorelines, the first of which defines a border of a vertical area and the second of which forms a border of a horizontal area when the barricade is erected. The flat sheet portions each have a sloping surface between the scorelines when the barricade is erected. The vertical areas of the two flat sheet portions are permanently secured to each other.
In one embodiment, a warning light is incorporated within the traffic barricade by forming holes in the vertical areas and attaching plastic lenses over each of the holes.
In another embodiment, the first and second flat sheet portions are formed from a single flat sheet whereby either the vertical areas of the first and second sheet portions are joined along a fold line or else the horizontal areas bordered by the second scorelines form a single, continuous horizontal area.
