Interstate vs. Intrastate Definitions

Interstate commerce is the movement of a shipment or service across state or international borders, or the intent to continue a movement within a state that originated from another state or country. In practical terms, you could still be considered interstate commerce even if you never cross the state line, depending upon the origin and destination of the shipment or service.

Intrastate commerce is the movement that originates in a single state, moves in that state only and delivers in that originating state.

Interstate vs. Intrastate Interpretation

Question 6:
How does one distinguish between intra-and interstate commerce for the purposes of applicability of the FMCSRs?

Interstate commerce is determined by the essential character of the movement, manifested by the shipper's fixed and persistent intent at the time of shipment, and is ascertained from all of the facts and circumstances surrounding the transportation. When the intent of the transportation being performed is interstate in nature, even when the route is within the boundaries of a single State, the driver and CMV are subject to the FMCSRs.
