ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,448,058, issued on Oct. 21.

"Laterally inset trailer skirt and inner wheel skirt panel, each reducing vehicle drag" was invented by Garth L. Magee (Hawthorne, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "An inner wheel skirt panel reduces overall vehicle drag by inhibiting air from otherwise being displaced laterally inward by the passing wheels of the moving vehicle.
