ABSTRACT:
A vented tailgate construction for dumptrucks, pickup trucks and other vehicles which permits the free flow of air through the tailgate thereby decreasing air drag caused by the tailgate, increasing fuel efficiency, and increasing the field of rear vision for the vehicle operator. The tailgate construction discloses a shutter mechanism for preventing the loss of cargo when the vehicle's cargo compartment contains loose, fine, small and/or light particulate matter which might otherwise pass through the vented tailgate construction.
