FMCSA / DOT mandate
Authority, MC & DOT
The filings that make you legal to get paid.
Do this now
Do not book a load until SAFER shows Active, insurance on file, and BOC-3 accepted. Paid fees are not the same as Active.
Must-have
- USDOT number (CMV 10,001+ lbs in interstate commerce, or hazmat, or for-hire interstate).
- MC (operating authority) if you are for-hire interstate with regulated freight.
- BOC-3 process-agent filing before the MC goes live.
- Insurer-filed BMC-91 / BMC-91X — you cannot file this yourself.
- UCR (Unified Carrier Registration) every year.
- MCS-150 update every 24 months, and within 30 days of a real change (fleet, mileage, name).
The rule
49 CFR 390.19 / MCS-150
Biennial update of your motor-carrier identification. Miss it and FMCSA can deactivate the USDOT.
49 CFR 366 — BOC-3
Every state must have a named process agent. No BOC-3, no authority.
FMCSA URS
First-time USDOT/MC is filed in the Unified Registration System, not a paper MCS-150.
New Entrant (18 months)
New interstate carriers sit in the New Entrant Safety Assurance Program until they pass a safety audit.
What they don’t publish
- People sell you ‘authority packages’ that file the MC and then ghost the insurance and BOC-3. The MC sits Inactive. You cannot legally haul.
- Intrastate-only Florida hotshot (never crossing a state line, never handling interstate freight) may not need an MC. The second that freight is part of an interstate move, you do.
- Check SAFER yourself. Do not trust a screenshot from a dispatcher.
