Title 49 › Subtitle 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 look into companies that control, are controlled by, or are under common control with those carriers when their work affects the carriers, and can get any information needed from them. For motor carriers, including those that carry migrant workers and private motor carriers, the Secretary can work with State authorities, hold joint hearings, use State records and staff, and make agreements to enforce State and federal highway safety rules. The Secretary can subpoena witnesses and records from anywhere in the United States to a hearing, and ask the local federal district court to enforce a subpoena if someone disobeys it; the court can punish refusal as contempt. The Secretary and parties can take sworn depositions and order records. Depositions can be taken before certain federal or state judges, court officers, city officials, or a neutral notary. Written notice must name the witness and state the time and place. A transcript must be made and signed by the witness. Foreign testimony can be taken before a Secretary‑designated or agreed officer and must be filed promptly. Witnesses and the person taking the deposition get the same fees and travel pay as in U.S. courts.
