(b) Notwithstanding subdivision (a), a truck tractor, operated by a motor carrier whose owner is licensed by the Department of the California Highway Patrol to transport explosives pursuant to Division 14 (commencing with Section 31600), may be equipped with a cargo container used exclusively for the transportation of explosives or munitions-related security material, as specified by the United States Department of Defense.
