(1) An application for an adjudicative proceeding must be filed in writing within thirty days of the action that is the subject of the appeal.

(2) An application for an adjudicative proceeding shall specify the issue or issues to be adjudicated in the proceeding and must be signed by the applicant or the applicant's representative. The signature of an applicant or the applicant's representative constitutes a certificate by the applicant or applicant's representative that the applicant or applicant's representative has read the application; that to the best of the applicant's or applicant's representative's knowledge, information, and belief, formed after reasonable inquiry it is well grounded in fact and is warranted by existing law or a good faith argument for the extension, modification, or reversal of existing law, and that it is not interposed for any improper purpose, such as to harass or to cause unnecessary delay or needless increase in the cost of adjudication. If an application is not signed, it shall be stricken unless it is signed promptly after the omission is called to the attention of the applicant or applicant's representative. If an application is signed in violation of this rule, the presiding officer, upon motion or upon its own initiative, may impose upon the person who signed it, a representative party, or both, an appropriate sanction, which may include dismissal of the case.

(3) An application for an adjudicative proceeding shall be served by certified mail, registered mail, or personal service on the Office of the Secretary of the Washington State Department of Transportation, 3D25 Transportation Building, Olympia, WA 98504-7316.
