49 CFR § 385.15 - Administrative review.
(b) The motor carrier's request must explain the error it believes the FMCSA committed in issuing the safety rating. The motor carrier must include a list of all factual and procedural issues in dispute, and any information or documents that support its argument.
(c) The motor carrier must submit its request in writing to the Chief Safety Officer, Federal Motor Carrier Safety Administration, 1200 New Jersey Ave., SE., Washington, DC 20590-0001.
(1) If a motor carrier has received a notice of a proposed “unsatisfactory” safety rating, it should submit its request within 15 days from the date of the notice. This time frame will allow the FMCSA to issue a written decision before the prohibitions outlined in § 385.13 (a)(1) and (2) take effect. Failure to petition within this 15-day period may prevent the FMCSA from issuing a final decision before such prohibitions take effect.
(2) A motor carrier must make a request for an administrative review within 90 days of the date of the proposed safety rating issued under § 385.11 (c) or a final safety rating issued under § 385.11 (b), or within 90 days after denial of a request for a change in rating under § 385.17(i).
(d) The FMCSA may ask the motor carrier to submit additional data and attend a conference to discuss the safety rating. If the motor carrier does not provide the information requested, or does not attend the conference, the FMCSA may dismiss its request for review.
(f) The decision constitutes final agency action.
