An adjustable body skirting assembly and a vehicle that includes the assembly. The assembly includes a support structure and a skirt member. The support structure includes a side surface and a bottom surface, and the skirt member is supported by the support structure. The skirt member is movable between a deployed position in which the skirt member is disposed transverse to the bottom surface of the support structure such that the skirt member and the side surface cooperate with each other to define a wall configured to redirect an airflow away from the bottom surface, and a retracted position in which the skirt member retracts relative to the side surface such that the wall is removed which allows the airflow to interact with the bottom surface. The assembly includes an actuator coupled to the skirt member and configured to move the skirt member to the deployed and retracted positions.
