ABSTRACT:
An air deflector secured rigidly to the cabin roof of the tractor of a tractor-trailer rig includes a pair of side panels which converge in a forward juncture line. Each panel is inwardly and rearwardly inclined from the forward juncture line at a substantially constant angle of attack "X" of between 20.degree. and 30.degree. off the vertical and each panel is shaped with concave-convex curvature for channeling the air rearwardly and upwardly. The deflector is capable of effectively diverting both high and low speed air currents to reduce engine strain and fuel consumption at all vehicle speeds.
