No motor carrier shall enter into or become a party to any combination, contract, agreement or understanding, written or oral, express or implied, to prevent by any arrangement, or by change of arrangement of time schedule, by carriage or by any other means or device whatsoever the carriage of household goods from being continuous from the place of shipment to the place of destination. No breakage of bulk, stoppage or interruption of carriage made by any motor carrier shall prevent the carriage of household goods from being treated as one continuous carriage from the place of shipment to the place of destination. Nor shall any such breakage of bulk, stoppage or interruption of carriage be made or permitted by any motor carrier except it be done in good faith for a necessary purpose without intention to avoid or unnecessarily interrupt or delay the continuous carriage of such household goods or to evade any of the provisions of law, of this chapter, or of any order or decision of the division of motor carrier and railroad safety.
