Abstract

The traffic safety device of the invention incorporates a see-through, vinyl or rubber-type bag, inflatable to a height of some 4-5 feet and to a width to approximate that of a typical lane of traffic. The inside rear surface of the bag is provided with a reflective material to reflect headlight illumination through any one of a number of highway warning signs that may be draped across the outside front surface of the bag. A pair of elastic straps are stretched to encircle the bag as it is inflated, and automatically pull and guide the bag back into a storage box for the device as the bag is deflated and the straps return to their original lengths.
