(1) The commission interprets the provisions of 49 U.S.C. § 14501 as preempting the requirements of state laws and regulations relating to intrastate fares for the transportation of passengers by an interstate motor carrier of passengers operating over a regular route authorized by the Federal Motor Carrier Safety Administration (FMCSA). Because of this federal preemption, the commission will no longer require the filing of rate tariffs or time schedules for the transportation of passengers in Washington intrastate commerce by interstate motor carriers of passengers, if that transportation is provided over a regular route authorized by the FMCSA.

(2) Auto transportation companies operating in Washington intrastate commerce on routes not authorized by the FMCSA are subject to the tariff and time schedule rules contained in this chapter.

(3) Auto transportation companies operating over routes authorized by the FMCSA and over routes not authorized by the FMCSA must file tariffs and time schedules for those routes not authorized by the FMCSA.
