Missouri Revised Statutes Title X. Taxation and Revenue § 142.830. License required for interstate motor fuel uses, effect of reciprocity agreement, single-trip permit, fee

1. It is unlawful for any person to act as an interstate motor fuel user without being licensed as such unless the motor fuel user is licensed under a reciprocity agreement. However, as to a motor vehicle operated in this state in the course of interstate traffic by an unlicensed interstate motor fuel user, a single trip motor fuel tax permit authorizing operation of such vehicle for a single trip through the state, or from a point on the border of this state to a point within and return to the border may be issued upon proper application and in a manner prescribed by the director. Any person found to have not purchased a trip permit when so required shall immediately purchase such permit. The fee for each permit shall be ten dollars, and the permit shall be valid for a period of seventy-two hours. Permits shall be made available at official highway weigh stations.

2. A single trip permit shall be issued for each vehicle for which application is made, and the application fee for such permit shall apply only to the vehicle for which the permit is issued. A trip permit shall not be issued to anyone whose license is currently in a revoked status. Evidence of the issuance of such trip permit or in the alternative the payment and civil penalty thereof shall be furnished to the director, his agents, appointees or any officer of the Missouri state highway patrol upon demand.
