FMCSA Biennial Update: MCS-150 Requirements

Who This Applies To

• For-hire motor carriers transporting regulated property or passengers in interstate commerce and needing FMCSA operating authority.
• New trucking businesses, owner-operators, and dispatchers verifying initial FMCSA registration requirements before the first load.
• Freight brokers and freight forwarders applying for or maintaining FMCSA operating authority and verifying insurance and BOC-3 requirements.

What To Verify

• Whether the operation is for-hire or private, interstate or intrastate, property or passengers — these distinctions determine which FMCSA registrations and authority types are required.
• Current FMCSA application fees, processing timelines, required insurance forms (BMC-91, BMC-91X), and bond amounts through the FMCSA Unified Registration System.
• Whether state intrastate authority is needed in addition to or instead of federal FMCSA authority, and which state agency handles intrastate carrier registration.
• BOC-3 process agent filing deadlines and insurance effective dates required before FMCSA authority becomes active and the carrier can legally dispatch.

Step-by-Step Overview

1. Determine the correct authority type: motor carrier (property-carrying or passenger-carrying), broker, freight forwarder, or private carrier — each has different FMCSA registration requirements.
2. Register for a USDOT number through the FMCSA Unified Registration System (URS) and complete the MCS-150 carrier information form.
3. Apply for operating authority (MC number) if for-hire transportation in interstate commerce is involved — private carriers generally do not need an MC number.
4. File BOC-3 through a registered process agent company to designate agents in required states before operating authority activates.
5. File required insurance forms with FMCSA (Form BMC-91 or BMC-91X for carriers, BMC-84 or BMC-85 bond for brokers) and confirm authority status in FMCSA's SAFER system before dispatching.

Common Mistakes

• Beginning dispatching or hauling for hire before FMCSA authority is confirmed as active in SAFER — authority applications have a protest period and processing time.
• Assuming a USDOT number alone provides for-hire operating authority — for-hire carriers transporting regulated commodities in interstate commerce also need an MC number.
• Filing BOC-3 without confirming coverage in every state where authority applies, or delaying BOC-3 filing until after authority approval causes activation delays.
• Missing the biennial MCS-150 update deadline, which causes USDOT status to become delinquent and can result in out-of-service orders during roadside inspections.
