A tractor (12) and trailer (14) coupled together in tandem towing relationship is provided with an air deflector system (10) attached to the tractor (12) for aerodynamically reducing the drag on such combination by enclosing the space between the cab (12a) of the tractor (12) and the trailer (14). A support means (40) is attached to the frame (42) of the tractor (12). A top air fairing (16) is movably attached to the support means (40) for extending from the top of the cab to the top of the trailer. Two side fairings (18a,18b) are movably attached to the support means (40) for extending from the rear of the cab (12a) to the trailer (14), and wherein the side fairings mate with the top fairing. A means is provided for moving the fairings (16,18a,18b) from one position to another based upon the alignment between the trailer (14) and the tractor (12).
