Fast Trucking ComplianceCompliance FAQ
Do I need an MC number for intrastate trucking?
No. An MC (motor-carrier) number is FMCSA operating authority required only for for-hire interstate or international transportation under 49 USC §13902. Pure intrastate carriers - meaning the truck never crosses state lines and the cargo never originated in or is destined for another state - do not need an MC docket. You will, however, almost certainly still need a USDOT number under your state law (most states adopted federal USDOT registration as a condition of running a commercial vehicle in commerce), state intrastate operating authority issued by your state DOT or PUC, intrastate insurance certificates, and possibly a state apportioned plate. The line FMCSA cares about is the federal interstate one. Intrastate authority lives entirely under state law and varies state-by-state, so check with your home-state DOT office before assuming you can skip the MC.
Why it matters
FMCSA jurisdiction begins the moment cargo or passengers cross a state line - even once. A Texas-only flatbed running rebar between Houston and Dallas is intrastate; the same flatbed delivering one load to Shreveport is interstate from that point forward and triggers MC authority, BIPD on the federal $750,000 schedule, BOC-3 process-agent designation in all 50 states, and UCR registration.
States that piggyback on the federal USDOT framework still issue intrastate authority separately. California requires a CA Number from the CHP, Texas requires TxDMV motor carrier registration, Florida uses an intrastate authority docket with the DOT. None of these are an MC number, but skipping them is the same kind of operating-without- authority violation roadside enforcement looks for.
If a single cross-border load is on the table - even a one-time relocation move - get the MC before that trip. Operating one mile across the line without authority is a $13,000+ FMCSA civil penalty under 49 USC §14901.
