49 U.S.C. 13902. Registration of motor carriers

Penalties for Failure To Comply With Registration Requirements. In addition to other penalties available under law, motor carriers that fail to register their operations as required by this section or that operate beyond the scope of their registrations may be subject to the following penalties:

(1) Out-of-service orders. If, upon inspection or investigation, the Secretary determines that a motor vehicle providing transportation requiring registration under this section is operating without a registration or beyond the scope of its registration, the Secretary may order the vehicle out-of-service. Subsequent to the issuance of the out-of-service order, the Secretary shall provide an opportunity for review in accordance with section 554 of title 5, United States Code; except that such review shall occur not later than 10 days after issuance of such order.

(2) Permission for operations. A person domiciled in a country contiguous to the United States with respect to which an action under subsection (c)(1)(A) or (c)(1)(B) is in effect and providing transportation for which registration is required under this section shall maintain evidence of such registration in the motor vehicle when the person is providing the transportation. The Secretary shall not permit the operation in interstate commerce in the United States of any motor vehicle in which there is not a copy of the registration issued pursuant to this section.

Do not act or rely upon this statute without ensuring that it is up to date and without seeking professional legal advice.
