An airflow improvement device for improving aerodynamic characteristics of a tractor-trailer truck comprises a side panel extending between the side of the tractor and the side of the trailer. A first end of the side panel is fixed to one of the tractor or trailer and the other end of the side panel is slidably restrained in a pocket structure mounted to the other of the tractor or the trailer so that the side panel will bend to form a smooth curved transition surface between the sides of the tractor and the trailer when the truck articulates to make a turn.
