Sec. 23. (a) Every common carrier by motor vehicle shall file with the department, and print and keep open to public inspection, tariffs showing all rates, fares, charges for transportation, and all service in connection therewith, of passengers or household goods in intrastate commerce between points:

(1) on its own route;

(2) on the route of any other common carrier; or

(3) on the route of any common carrier by railroad;

when and as through routes and joint rates are established.

(b) The department may prescribe the form and manner in which the tariffs shall be published and may reject any tariff filed with it that is not in compliance with this section. When so rejected, the tariff is void, and its use shall be unlawful.

(c) A common carrier by motor vehicle shall not charge, demand, collect, or receive a greater or less or different compensation for transportation or for any service in connection therewith between points enumerated in the tariff than the rates, fares, and charges specified in the tariffs in effect at the time. A carrier shall not refund or remit in any manner or by any device, directly or indirectly, personally or by agent, any portion of rates, fares, or charges so specified, and shall not extend to any person any facilities for transportation except as are specified in its tariffs.

(d) A change may not be made in any fare, charge, rule or practice for or in connection with the transportation of passengers or household goods except after thirty (30) days notice of the proposed change. The notice must plainly state the change proposed to be made and the effective date of the change. The department, upon complaint or upon the department's own motion, may suspend any tariff making any changes provided in this chapter within twenty (20) days after the filing of the tariff and not thereafter.

(e) The department may, for good cause shown, allow changes upon notice in less time than specified and permit tariffs to be filed and become effective in particular instances on shorter notice than stated in subsection (d).

(f) Whenever the carrier operating a local transportation system wholly within one (1) county files a tariff or schedule of increased rates or fares affecting its patrons in any municipality in which the carrier renders service, the carrier shall give notice by registered mail, on the date the tariff is filed with the department, to the executive and legislative body of the municipality and shall enclose a copy of the tariff filed with the department.

(g) A common carrier by motor vehicle shall not engage in the transportation of passengers or household goods unless the tariffs have been filed and published in accordance with this chapter.
