Arkansas Code Title 23. Public Utilities and Regulated Industries § 23-13-244. Tariffs, generally

(a)(1) Whenever an applicable tariff has not already been prescribed by the Arkansas Department of Transportation, every common carrier by motor vehicle shall file with the department and shall keep open to public inspection at all times tariffs showing all the rates, fares, and charges for transportation, and all services in connection therewith, of passengers or property between points on its own route and points on the route of any other common carrier, or on the routes of any common carrier by railroad, express, or water, when a through route and joint rate shall have been established.

(2) The rates, fares, and charges shall be stated in terms of lawful money of the United States.

(3) The tariffs required by this section shall be published, filed, and posted in such form and manner and shall contain such information as the department by rule shall prescribe.

(4) The department is authorized to reject any tariff filed with it which is not in consonance with this subchapter and with its rules. Any tariff so rejected by the department shall be void, and its use shall be unlawful.

(b)(1) No common carrier by motor vehicle shall charge, demand, collect, or receive a greater, lesser, or different compensation for transportation, or for any service in connection therewith, between the points enumerated in the tariff, than those rates, fares, and charges specified in the tariffs in effect at the time.

(2) No such carrier shall refund or remit in any manner or by any device, directly or indirectly, or through any agent or broker or otherwise any portion of the rates, fares, or charges so specified, nor shall that carrier extend to any person any privilege or facilities for transportation except as are specified in its tariff.

(c)(1) No change shall be made in any rate, fare, charge, or classification, or the value of the service thereunder, specified in any effective tariff of a common carrier by motor vehicle except after thirty (30) days' notice of the proposed change filed and posted in accordance with subsection (a) of this section.

(2) The notice shall plainly state the change proposed to be made and the time when the change will take effect.

(3) The department, in its discretion and for good cause shown, may allow such change upon notice less than that specified in this section or may modify the requirements of this section with respect to posting and filing of tariffs either in particular instances or by general order applicable to special or peculiar circumstances or conditions.
