This document amends the Customs Regulations to allow certain foreign-based commercial motor vehicles, which are admitted as instruments of international traffic, to engage in the transportation of merchandise or passengers between points in the United States where such transportation is incidental to the immediately prior or subsequent engagement of such vehicles in international traffic. Any movement of these vehicles in the general direction of an export move or as part of the return movement of the vehicles to their base country shall be considered incidental to the international movement. The benefit of this liberalization of current cabotage restrictions inures in particular to both the United States and foreign trucking industries inasmuch as it allows more efficient and economical utilization of their respective vehicles both internationally and domestically.
