A side skirt assembly for attachment to a trailer of a tractor-trailer, particularly to a trailer frame comprising transverse structural support members extending between sides of the trailer, the side skirt assembly comprising:

• an elongated skirt panel having an inner surface and an outer surface;
• an elongated support coupled to the elongated skirt panel on the inner surface thereof proximate an upper edge of the elongated skirt panel and extending at least a portion of a length of the elongated skirt panel;
• one or more skirt support members comprising a positional biaser and configured to couple the elongated skirt panel to a corresponding one or more or of the transverse structural support members, wherein the one or more skirt support members extend downwardly from the one or more transverse structural support members, and wherein the one or more skirt support members are configured to assist upward and inward pivoting of the elongated skirt panel to reduce impact damage;
• and
• one or more couplers for coupling the one or more skirt support members to the corresponding one or more of the transverse structural support members, wherein the one or more couplers comprises at least one adjustable attacher structured and arranged to adjustably attach the one or more skirt support members to the one or more transverse structural support members.
