Provided is an aerodynamic drag reduction apparatus for reducing aerodynamic drag on an over-the-road vehicle while underway. The aerodynamic drag reduction system includes a frame assembly that is adapted to cooperate with a cargo-carrying portion of the over-the-road vehicle to couple the drag reduction apparatus to the over-the-road vehicle. First and second skirts are adapted to be supported beneath opposite lateral sides of the cargo-carrying portion of the over-the-road vehicle by arcuate rails. The first and second skirts are coupled to the frame assembly in a manner that allows thermal expansion and contraction of the first and second skirts relative to the frame assembly without warping of material forming an air-deflecting surface of the first and second skirts to an extent that would otherwise occur if the first and second skirts were fixedly connected to the frame assembly.
