ABSTRACT:
A portable expandable screen for blocking passing motorists' and pedestrians' views of accidents on a roadway to prevent rubbernecking and promote traffic flow and increased highway safety. The portable expandable screen has a plurality of panels assembled in a telescoping manner like an accordion. Each panel has an outside surface, an inside surface, an inside edge, and a bottom end. A horizontal track is located on the inside surface at the bottom end of every panel. A small wheel is fixed to the inside edge at the bottom end of every panel, for allowing the small wheel of one panel to be fitted within the track of an adjacent panel. This allows the panels to slide inwardly and outwardly in a telescoping manner to block accidents from view on the roadways.
