49 U.S.C. 13906. Security of motor carriers, brokers, and freight forwarders

(a) Motor Carrier Requirements.

(1) Liability insurance requirement. The Secretary may register a motor carrier under section 13902 only if the registrant files with the Secretary a bond, insurance policy, or other type of security approved by the Secretary, in an amount not less than such amount as the Secretary prescribes pursuant to, or as is required by, sections 31138 and 31139, and the laws of the State or States in which the registrant is operating, to the extent applicable. The security must be sufficient to pay, not more than the amount of the security, for each final judgment against the registrant for bodily injury to, or death of, an individual resulting from the negligent operation, maintenance, or use of motor vehicles, or for loss or damage to property (except property referred to in paragraph (3) of this subsection), or both. A registration remains in effect only as long as the registrant continues to satisfy the security requirements of this paragraph.

(2) Agency requirement. A motor carrier shall comply with the requirements of sections 13303 and 13304. To protect the public, the Secretary may require any such motor carrier to file the type of security that a motor carrier is required to file under paragraph (1) of this subsection. This paragraph only applies to a foreign motor private carrier and foreign motor carrier operating in the United States to the extent that such carrier is providing transportation between places in a foreign country or between a place in one foreign country and a place in another foreign country.

(3) Transportation insurance. The Secretary may require a registered motor carrier to file with the Secretary a type of security sufficient to pay a shipper or consignee for damage to property of the shipper or consignee placed in the possession of the motor carrier as the result of transportation provided under this part. A carrier required by law to pay a shipper or consignee for loss, damage, or default for which a connecting motor carrier is responsible is subrogated, to the extent of the amount paid, to the rights of the shipper or consignee under any such security.
