An air foil having a general shape of a half pyramid, but wherein when mounted in place, its rear edges are vertical. Such rear edges terminate in tapered marginal flanges which are angularly related to the remainder of the structure for air deflection purposes. This air foil can be cab mounted or mounted on the trailer in front of the dolly. Another form of air foil comprises a spoiler for the rear upper corner of a trailer. A further air foil comprises an air deflector for the bumper of a highway vehicle.

An air foil for the cab of a highway tractor having a box-like trailer: a foil structure having a pair of panels disposed at a substantial acute angle relative to one another to provide a substantially straight edge for cleaving into the air traveled by the vehicle, means for mounting the air foil structure on the roof of the tractor cab with the edge facing forwardly but at an acute angle to the horizontal and to the vertical, the rear edges of said panels lying in a vertical plane, said air foil structure having an opening formed in its nose portion to facilitate entry of air into said air foil structure, the rear margins of said panels terminating in outwardly flaring flanges for deflecting air laterally, said flanges tapering in width so as to decrease in size from the upper portions thereof to the lower portions, so that air deflection increases as the displacement of the flange from the sides of the trailer increases.
