Ohio Rev. Code § 4503.81
As used in the bus taxation proration and reciprocity agreement authorized by section 4503.80 of the Revised Code, with reference to Ohio, "administrator" means the registrar of motor vehicles.
The registrar may make such exemptions from the coverage of the agreement as may be appropriate and may make such changes in methods for the reporting of any information required to be furnished to this state pursuant to the agreement as, in the registrar's judgment, are suitable; provided that any such exemptions or changes shall not be contrary to the purposes set forth in article I of the agreement and shall be made in order to permit the continuance of uniformity of practice among the contracting states with respect to buses. Any such exemption or change shall be made by rule adopted under Chapter 119. of the Revised Code. Unless otherwise provided in any statute withdrawing this state from participation in the agreement, the governor shall be the officer to give notice of withdrawal therefrom.
The fees referred to in article IV (a) of the agreement shall include the fees provided in section 4503.04 of the Revised Code and the annual tax provided in section 4921.19 of the Revised Code. As to the state of Ohio, article V (d) shall mean that all fleets not subject to this compact shall continue to enjoy that reciprocity and those privileges extended by virtue of other provisions of the Revised Code.
Nothing contained herein shall be construed so as to permit a fleet which is prorating under the laws of another state to avoid proration under this compact.
The registrar of motor vehicles shall collect a fee of two dollars per bus for every bus registered under the provisions of article IV (a) for administration of the agreement, in addition to the fees provided in article IV (a).
The registrar of motor vehicles shall assess the operator of buses registered under the provisions of article IV (a) the actual cost of the registrar's auditing the accuracy of the fees paid by the operator in accordance with article IV (a).
The registrar of motor vehicles may renounce the participation of this state in the bus taxation proration and reciprocity agreement under article VI of section 4503.80 of the Revised Code, after finding that further participation in the compact is not in the best interests of the state. The registrar shall set forth the registrar's reasons in writing and serve notice of intention to renounce the compact upon the owner of each registered fleet. The registrar shall then certify the renunciation to the governor.
