# Interstate vs Intrastate Trucking: What's the Difference?

> Interstate trucking moves freight across a state line, or inside one state as part of a trip that started or will end outside it. Intrastate trucking starts, moves and ends within a single state. The line decides which rules apply: interstate for-hire carriers of regulated freight need FMCSA operating authority, while intrastate carriers follow their own state's registration and insurance rules.

## How FMCSA draws the line

49 CFR 390.5 counts three kinds of trips as interstate commerce:

- Between a place in one state and a place outside it, including outside the United States.
- Between two places in the same state by way of another state or a place outside the country.
- Between two places in the same state when the freight is part of a movement that began or ends outside that state.

## The trip that never leaves the state

The third case catches people out. A truck hauling an imported container from a port to a warehouse 200 miles inland in the same state can be in interstate commerce, because the freight's journey started overseas. Intrastate means everything that isn't interstate, so a carrier that only ever runs local freight with a local origin and destination stays intrastate.

On the MCS-150 a carrier marks one of three operation types: interstate, intrastate hazmat or intrastate non-hazmat. A carrier that registered intrastate and starts taking loads across state lines has to update that classification, and if it hauls regulated freight for pay it needs [operating authority](https://rookiefeed.com/glossary/operating-authority) before the first interstate load.

## Why sellers sort by it

An interstate for-hire carrier books broker loads across state lines, invoices those brokers and files federal liability coverage, so it's the carrier factors, dispatchers and truck insurance agents sell to. Every row on Rookiefeed's list is a new FMCSA authority grant, and 99.7% of recent grants were registered for interstate operation. The operation type is a column on each row; see [new authority data fields](https://rookiefeed.com/guides/new-authority-data-fields).

## Questions

### Does an intrastate carrier need an MC number?

No. FMCSA operating authority, and the MC docket that goes with it, covers for-hire carriers of regulated freight in interstate commerce. An intrastate carrier answers to its state, and many states ask for a USDOT number and their own state credentials instead.

### Can an intrastate carrier haul across state lines?

Not under its intrastate registration. It has to update its USDOT registration to interstate operation, and if it hauls other companies' regulated freight for pay it needs granted operating authority, a liability filing at the federal minimum and a BOC-3 before taking an interstate load.
