Title 49 › SUBTITLE I — DEPARTMENT OF TRANSPORTATION › CHAPTER 5 — SPECIAL AUTHORITY › SUBCHAPTER I — POWERS › § 504
Requires carriers, lessors, and related groups to keep records and file reports, and lets the Secretary of Transportation decide the forms, what must be reported, how long records must be kept, and who may inspect them. An association is a group that helps carriers. A carrier means a motor carrier, a motor carrier of migrant workers, a motor private carrier, or a rail carrier. A lessor is someone who owns a railroad leased to a rail carrier or who leases the right to operate as a motor carrier. “Lessor” and “carrier” also include a receiver or trustee. The Secretary can make companies and associations file annual, periodic, or special reports and can require reports from people who supply rail cars or heat/cold protection. The Secretary or a designated employee (and for motor carriers, possibly a contractor or an employee of a grant recipient under section 31102) may inspect equipment and records with proper ID. Annual reports must cover the 12-month period ending on December 31 and be filed by the end of the third month after that year ends, and may be sworn. Parts of motor-carrier accident reports and Secretary investigations cannot be used as evidence in civil damage lawsuits.
