§ 31-6.1-1. Agreement enacted. The Bus Taxation Proration Agreement is enacted into law and entered into with all jurisdictions legally joining in the form substantially as follows:

Article I. Purposes and Principles

(a) Purposes of agreement. It is the purpose of this agreement to set up a system by which any contracting state may permit owners of fleets of buses operating in two or more states to prorate the registration of the buses in such fleets in each state in which the fleets operate on the basis of the proportion of miles operated within such state to total fleet miles, as defined in this agreement.

(b) Principle of proration of registration. It is declared that in making this agreement the contracting states adhere to the principle that each state should have the freedom to develop the kind of highway user tax structure that it determines to be most appropriate to itself; that the method of taxation of interstate buses should not be a determining factor in developing its user tax structure; and that annual taxes or other taxes of the fixed fee type upon buses, which are not imposed on a basis that reflects the amount of highway use, should be apportioned among the states, within the limits of practicality, on the basis of vehicle miles traveled within each of the states.

Article II. Definitions

(a) "State". State shall include the states of the United States, the District of Columbia, the territories of the United States, the provinces of Canada, and the states, territories and federal district of Mexico.

(e) "Base state". Base state shall mean the state from or in which the bus is most frequently dispatched, garaged, serviced, maintained, operated, or otherwise controlled, or also in the case of a fleet bus the state to which it is allocated for registration under statutory requirements. In order that this section may not be used for the purpose of evasion of registration fees, the administrators of the contracting states may make the final decision as to the proper base state, in accordance with article III(h) of this agreement, to prevent or avoid any evasion.

(f) "Bus". Bus shall mean any motor vehicle of a bus type engaged in the interstate transportation of passengers and subject to the jurisdiction of the interstate commerce commission, or any agency successor to it, or one or more state regulatory agencies concerned with the regulation of passenger transport.

Article III. General Provisions

(a) Effect on other agreements, arrangements, and understandings. On and after its effective date, this agreement shall supersede any reciprocal or other agreement, or understanding between any two or more of the contracting states covering, in whole or in part, any of the matters covered by this agreement. But this agreement shall not affect any reciprocal or other agreement, arrangement, or understanding between a contracting state and a state or states not a party to this agreement.

(j) Entry into force. This agreement shall enter into force and become binding between and among the contracting states when enacted or otherwise entered into by any two (2) states. Subsequently, it shall enter into force and become binding with respect to any state when enacted into law by that state. If the statutes of any state so authorize or provide, a state may become party to this agreement upon the execution of it by an executive or administrative official of the state acting on behalf of and for the state.

Article IV. Proration of Registration

(a) Applicability. Any owner of a fleet may register the buses of that fleet in any contracting state by paying to that other state the total registration fees in an amount equal to that obtained by applying the proportion of in-state fleet miles divided by the total fleet miles, to the total fees which would otherwise be required for regular registration of each and all of those vehicles in the other contracting state.

(1) All fleet pro-rata registration fees shall be based upon the mileage proportions of the fleet during the period of twelve (12) months ending on August 31 next preceding the commencement of the registration year for which registration is sought. The mileage proportions for a fleet not operated during that period in the state where application for registration is made will be determined by the administrator upon the sworn application of the applicant showing the operations during that period in other states, and the estimated operations during the registration year for which registration is sought in the state in which application is being made. If no operations were conducted during such period a full statement of the proposed method of operation shall be used.

(2) If any buses operate in two (2) or more states which permit the proration of registration on the basis of a fleet of buses consisting of a lesser number of vehicles than provided in article II(g), that fleet may be prorated as to registration in those states, in which event the buses in that fleet shall not be required to register in any other contracting states if each vehicle is registered in some contracting state except to the extent it is exempt from registration as provided in article III(b).

(3) If the administrator of any state determines, based on his or her method of the operation, that the inclusion of a bus or buses as a part of a fleet would adversely affect the proper fleet fee which should be paid to his or her state, having due regard for fairness and equity, the administrator may refuse to permit any or all of those buses to be included in his or her state as a part of such fleet.

(b) Total fleet miles. Total fleet miles, with respect to each contracting state, shall mean the total miles operated by the fleet (1) in such state, (2) in all other contracting states, (3) in other states having proportional registration provisions, (4) in states with which that contracting state has reciprocity, and (5) in those other states that the administrator determines should be included under the circumstances in order to protect or promote the interest of his or her state; except that in states having laws requiring proration on the basis of a different determination of total fleet miles, total fleet miles shall be determined on this basis.

(c) Leased vehicles. If a bus is operated by a person other than the owner as a part of a fleet which is subject to the provisions of this article, then the operator of that fleet shall be deemed to be the owner of that bus for the purposes of this article.

(d) Extent of privileges. Upon the registration of a fleet in a contracting state pursuant to this article, each bus in the fleet may be operated in both interstate and intrastate operations in that state except as provided in article III(e).

(e) Application for proration. The application for proration of registration shall be made in each contracting state upon substantially the application forms and supplements authorized by joint action of the administrators of the contracting states.

(f) Issuance of identification. Upon registration of a fleet, the state which is the base state of a particular bus of the fleet shall issue the required license plates and registration card for the bus and each contracting state in which the fleet (of which the bus is a part) operates shall issue a special identification identifying the bus as a part of a fleet which has fully complied with the registration requirements of that state. The required license plates, registration cards and identification shall be appropriately displayed in the manner required by or pursuant to the laws of each respective state.

(g) Additions to fleet. If any bus is added to a prorated fleet after the filing of the original application, the owner shall file a supplemental application. The owner shall register the bus in each contracting state in like manner as provided for buses listed in an original application and the registration fee payable shall be determined on the mileage proportion used to determine the registration fees payable for buses registered under the original application.

(h) Withdrawals from fleet. If any bus is withdrawn from a prorated fleet during the period for which it is registered or identified, the owner shall notify the administrator of each state in which it is registered or identified of that withdrawal and shall return the plates, and registration card or identification as may be required by or pursuant to the laws of the respective states.

(i) Audits. The administrator of each contracting state shall, within the statutory authority of the administrator, make any information obtained upon an audit of records of any applicant for proration of registration available to the administrators of the other contracting states.

(j) Errors in registration. If it is determined by the administrator of a contracting state, as a result of these audits or otherwise, that an improper fee has been paid that state, or if errors in registration are found, the administrator may require the fleet owner to make the necessary corrections in the registration of his or her fleet and payment of fees.

Article V. Reciprocity

(a) Grant of reciprocity. Each of the contracting states grants reciprocity as provided in this article.

(b) Applicability. The provisions of this agreement with respect to reciprocity shall apply only to a bus properly registered in the base state of the bus, which state must be a contracting state.

(c) Non-applicability to fleet buses. The reciprocity granted pursuant to this article shall not apply to a bus which is entitled to be registered or identified as part of a prorated fleet.

(d) Extent of reciprocity. The reciprocity granted pursuant to this article shall permit the interstate operation of a bus and intrastate operation which is incidental to a trip of such bus involving interstate operation.

(e) Other agreements. Nothing in this agreement shall be construed to prohibit any of the contracting states from entering into separate agreements with each other for the granting of temporary permits for the intrastate operation of vehicles registered in the other state; nor to prevent any of the contracting states from entering into agreements to grant reciprocity for intrastate operation within any zone or zones agreed, upon by the states.

Article VI. Withdrawal or Revocation

Any contracting state may withdraw from this agreement upon thirty (30) days' written notice to any other contracting state, which notice shall be given only after the repeal of this agreement by the legislature of such state, if adoption was by legislative act, or after renunciation by the appropriate administrative official of the contracting state if the laws of that state empower the administrator so to renounce.

Article VII. Construction and Severability

This compact shall be liberally construed so as to effectuate its purposes. The provisions of this compact shall be severable and if any phrase, clause, sentence or provision of this compact is declared to be contrary to the constitution of any state or of the United States, or the applicability of it to any government, agency, person or circumstance is held invalid, the validity of the remainder of this compact and the applicability of it to any government, agency, person, or circumstance shall not be affected by the invalidity. If this compact shall be held contrary to the constitution of any state participating in it, the compact shall remain in full force and effect as to the remaining party states and in full force and effect as to the state affected as to all severable matters.
