Summary

Employers and people who are covered by the federal vehicle safety rules must apply to the Secretary to register and get a USDOT number before they operate a commercial motor vehicle in interstate commerce. The Secretary can also choose to register someone who does not operate across state lines. The Secretary will only register someone who can follow the federal safety laws and rules and who, for the 3-year period before applying, is not tied by common ownership, management, control, or family to another operator that could not follow those rules—unless the applicant told the Secretary about that tie. The Secretary can suspend registration with notice or cancel it after notice and a chance for a hearing if the person breaks those rules, knowingly fails to comply, hides such relationships, refuses a required safety review, or loses related operating authority. Employers must update their registration within 30 days after changes to address, contact, officers, process agent, or other important information. States may still issue their own DOT numbers for operators that stay inside one state.
