Final rules are prepared by representatives from all relevant offices of FMCSA. The final rule is then submitted to the Administrator for his/her consideration and forwarded, as necessary, to the Office of the Secretary for review and approval. Once approved by the Office of the Secretary, and, if necessary, by the Office of Management and Budget's Office of Information and Regulatory Affairs, the final rule is signed by the Administrator. All final rules must be published in the Federal Register, unless all persons subject to the final rule are named and personally served with a copy of it.
