49 CFR § 376.11 - General leasing requirements.
Other than through the interchange of equipment as set forth in § 376.31, and under the exemptions set forth in subpart C of these regulations, the authorized carrier may perform authorized transportation in equipment it does not own only under the following conditions:
(2) Unless a copy of the lease is carried on the equipment, the authorized carrier shall keep a statement with the equipment during the period of the lease certifying that the equipment is being operated by it. The statement shall also specify the name of the owner, the date and length of the lease, any restrictions in the lease relative to the commodities to be transported, and the address at which the original lease is kept by the authorized carrier. This statement shall be prepared by the authorized carrier or its authorized representative.
(1) The authorized carrier shall prepare and keep documents covering each trip for which the equipment is used in its service. These documents shall contain the name and address of the owner of the equipment, the point of origin, the time and date of departure, and the point of final destination. Also, the authorized carrier shall carry documents with the leased equipment during its operation containing this information and identifying the lading and clearly indicating that the transportation is under its responsibility. These documents shall be preserved by the authorized carrier as part of its transportation records. Leases which contain the information required by the provisions in this paragraph may be used and retained instead of such documents. As to lease agreements negotiated under a master lease, this provision is complied with by having a copy of a master lease in the unit of equipment in question and where the balance of documentation called for by this paragraph is included in the freight documents prepared for the specific movement.
