Compliance 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 does it matter?
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 for intrastate carriers, and Florida requires a USDOT number on intrastate CMVs of 26,001+ lbs or placarded hazmat (Fla. Stat. 316.302). 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 across the line without authority can bring FMCSA civil penalties under 49 USC §14901.
