Title 49 › SUBTITLE IV — INTERSTATE TRANSPORTATION › PART B — MOTOR CARRIERS, WATER CARRIERS, BROKERS, AND FREIGHT FORWARDERS › CHAPTER 139 — REGISTRATION › § 13906
Requires motor carriers, brokers, and freight forwarders to put up bonds, insurance, or other financial security before they can register with the Department of Transportation. Motor carriers must carry at least the amount the Secretary sets and any amounts required by sections 31138 and 31139 and by state law. That money must be enough to pay judgments for injury, death, or property damage (up to the security amount). Registration stays valid only while the carrier keeps the required security. Not later than 120 days after the Unified Carrier Registration Act of 2005, certain non‑private carriers had to file required security. The Secretary can also require foreign carriers to file security when they operate between foreign places, can require insurance to pay shippers or consignees for cargo damage, and allows a carrier who pays a shipper to use the security to recover that payment. Brokers and freight forwarders must file a surety bond, trust, or other financial security the Secretary finds adequate. Group bonds are allowed. Trusts must hold assets that can pay claims right away. The security must cover claims for unpaid freight charges under chapter 135 if the broker or forwarder agrees, the surety finds the claim valid when the broker/forwarder does not respond, or the claim becomes a judgment. Sureties must answer claims within 30 days and explain denials in writing. The prevailing party in a dispute can recover costs and attorney’s fees. Each broker and each freight forwarder must have at least $75,000 in security. If the security is canceled, the holder must notify the Secretary at least 30 days before cancellation and the Secretary will post that notice. The Secretary must suspend registration if security falls below the required amount. On insolvency, the surety must give notice, allow 60 days for claims (starting when the Secretary publishes the notice), and pay uncontested claims within 30 days after that 60‑day period or pay pro rata if claims exceed available funds. The Secretary or the U.S. Attorney General may sue to enforce these rules. A surety that breaks the rules can be fined up to $10,000 and barred from providing broker or freight‑forwarder security for 3 years. Attorney fees and administrative costs cannot be deducted from the required security. The Secretary decides exact types and amounts of coverage, may approve self‑insurance (with rules), and must set notice timing and the endorsement form to attach to policies and bonds. Carriers already allowed to self‑insure as of January 1, 1996 keep that right unless it is revoked for good cause after notice and a hearing.
