49 CFR §385.15

1. (a)A motor carrier may request FMCSA to conduct an administrative review if it believes FMCSA has committed an error in assigning its proposed or final safety rating in accordance with § 385.11.
2. (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.
3. (c)The motor carrier must submit its request in writing to the Assistant Administrator, ATTN: Adjudications Counsel, Federal Motor Carrier Safety Administration, 1200 New Jersey Ave., SE., Washington, DC 20590-0001.
   1. (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. (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).
4. (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.
5. (e)The FMCSA will notify the motor carrier in writing of its decision following the administrative review. The FMCSA will complete its review:
   1. (1)Within 30 days after receiving a request from a hazardous materials or passenger motor carrier that has received a proposed or final “unsatisfactory” safety rating.
   2. (2)Within 45 days after receiving a request from any other motor carrier that has received a proposed or final “unsatisfactory” safety rating.
6. (f)The decision constitutes final agency action.
7. (g)Any motor carrier may request a rating change under the provisions of § 385.17.
