1. Common carriers of household goods may establish reasonable through routes or interline service and joint rates, charges and classifications with other such carriers or with common carriers by railroad or express; and common carriers of passengers may establish reasonable through routes and joint rates, fares or charges with other such carriers or with common carriers by railroad. In case of such joint rates, fares, charges or classifications, it shall be the duty of the participating carriers to establish just and reasonable regulations and practices in connection therewith, and just, reasonable and equitable divisions thereof as between the carriers participating therein which shall not unduly prefer or prejudice any of such participating carriers and shall not result in any rate, fare, charge, classification, regulation, or practice that is unjust or unreasonable to the shipper or receiver of the household goods. Carriers of household goods participating in through routes or interline service shall publish joint tariffs and evidence of concurrence or acceptance thereof, in accordance with section 387.080, or individual tariffs for each participating carrier, which shall set forth the joint or individual rates, fares, charges, classifications, regulations, practices, and division of rates applicable to such through routes or interline service, all in accordance with the applicable provisions in chapter 387.

2. The state highways and transportation commission may, whenever deemed by it to be necessary or desirable in the public interest, after hearing, upon complaint or upon its own motion, order the establishment of just and reasonable through routes and joint rates, fares, charges, regulations or practices, applicable to the transportation of passengers by common carriers.
