        (3)         An air or vacuum storage system must—

            (a)         be built to give a visible or audible warning to the driver of the towing vehicle, while in a normal driving position, of a lack of air or vacuum that would prevent the brakes from meeting the performance standards of rule 122; and

            (b)         be safeguarded by a check valve or other device against loss of air or vacuum if the supply fails or leaks.
