Title 49 › SUBTITLE I — DEPARTMENT OF TRANSPORTATION › CHAPTER 5 — SPECIAL AUTHORITY › SUBCHAPTER I — POWERS › § 502
The Secretary of Transportation must carry out the rules in this chapter. The Secretary can investigate and report on how rail and motor carriers run their businesses. The Secretary can also check businesses that control or are controlled by those carriers when their work affects the carriers. The Secretary can require carriers and related companies to give needed information. For motor carriers (including those carrying migrant workers and private carriers), the Secretary can work with State agencies, hold joint hearings, use State records and services, and make agreements with States to enforce highway safety rules. The Secretary can require witnesses and records to come to a hearing or investigation anywhere in the United States. If someone ignores that requirement, the Secretary or a party can ask the local federal district court to enforce it, and the court can punish contempt. The Secretary and parties may take sworn statements outside of hearings (depositions) and order records; if someone refuses, the Secretary can subpoena them. Depositions can be taken before various judges, court clerks, mayors, or a notary who is not a party’s lawyer. Foreign witnesses’ testimony may be taken by an officer the Secretary names or the parties agree on, and depositions must be filed. Witnesses and the person taking the deposition get the same fees and travel pay as in U.S. courts.
