Abstract: A truck for pulling a semi-trailer includes an operator cab positioned on a frame and a fifth wheel mounted on the frame for receiving an underside of the semi-trailer. The trailer when attached to the truck defines a gap between a forward most portion of the semi-trailer and rearward most portion of the operator cab. A fairing can be located on the frame, aft of the operator cab and forward of at least a portion of the fifth wheel. The fairing can block at least a portion of the air flow attempting to enter the gap from below the frame.
