A retractable fairing for reducing aerodynamic drag at a rear end of a commercial motor vehicle (CMV) may comprise a streamlining element having a medial plane and an airflow surface for streamlining air flow. A suspension frame may have an element end for hingedly supporting the streamlining element at approximately the medial plane and may have a trailer end for hingedly mounting the suspension frame to approximately an outer vertical corner of the rear end and may include a trailer hinge allowing the streamlining element to move in a horizontal plane into a folded position adjacent to the rear end. A pair of streamlining elements of complementary shape may be each mounted by a suspension frame to respective left and right halves of the rear end and placed in the folded position, the medial planes of each element facing one another and the streamlining elements collectively forming the retractable fairing.
