Claim:
A semi tractor and trailer fairing comprising: brackets attached to a forward face of the trailer near each front corner of the forward face; at least one adjustable length right panel and at least one adjustable length left panel residing in a gap between the tractor and trailer and configured to block a cross wind air flow between the tractor and the trailer, and attached to the brackets, the panels comprising a curved body, curving forward and inward towards the tractor; adjustable length struts reaching between the forward face of the trailer to an inner surface of each panel, wherein the panels are pivotally mounted to the brackets and positioned by the adjustable length struts, the adjustable length struts adjustable without detaching from the panels and the trailer, allowing the struts to be shortened to allow the panels to be easily folded inward to provide clearance for sharp maneuvers in yards; and flaps are attached to a forward edge of each panel, approximately perpendicular to an outer surface of each panel, the flaps extending outward with respect to the direction of travel of the semi tractor and trailer to further block the cross wind air flow between the tractor and the trailer.
