Transportation Compliance & Verification FAQs
What is the difference between a USDOT number and an MC number?
A USDOT number is a safety registration identifier required for all commercial motor vehicles in interstate commerce to track inspections and crash data. An MC (Motor Carrier) docket number represents operating authority, granting commercial permission to transport regulated cargo across state lines for hire or operate as a freight broker.
What does Active Authority vs Inactive or Out of Service mean?
Active Authority (such as "Authorized for Property") confirms that the company is legally authorized to transport freight or broker loads with required insurance on file. Inactive or Revoked authority means the entity cannot legally move for-hire freight. An Out-of-Service order prohibits the carrier from operating commercial vehicles due to safety or administrative violations.
What is the difference between a freight broker, a motor carrier, and a freight forwarder?
A motor carrier physically transports freight with commercial power units and holds BMC-91X primary liability insurance. A freight broker arranges transportation without owning trucks and maintains a \$75,000 BMC-84 surety bond. A freight forwarder consolidates shipments, issues bills of lading, assumes carrier cargo liability, and holds Form BMC-34 cargo insurance.
What are the Form BMC-91X and Form BMC-84 filing requirements?
Form BMC-91X is the official certificate of public liability insurance (\$750,000 to \$5,000,000) filed with FMCSA for motor carriers. Form BMC-84 is the \$75,000 surety bond (or BMC-85 trust fund) required for licensed property freight brokers to guarantee carrier payments under 49 U.S.C. 13906.
How do I check a trucking company or verify a freight broker before booking?
Always: 1) Query the USDOT or MC number in TransportTrace to confirm active operating status; 2) Confirm that insurance (BMC-91X) or broker bond (BMC-84) is currently on file without cancellation notices; 3) Review roadside inspection Out-of-Service rates; and 4) Verify registered physical address and corporate phone numbers to prevent fraudulent identity theft.
