If an individual fails to choose one of the methods of proceeding in section 39-06.1-02 or 39-06.1-03, the individual is deemed to have admitted to commission of the charged violation, and the official having jurisdiction shall report the admission to the director within ten days after the date set for the hearing. Failure to appear at the time designated, after signing a promise to appear, if signing is required by law, or failure to appear without paying the statutory fee or posting and forfeiting bond is a class B misdemeanor. Failure to appear without just cause at the hearing is deemed an admission of commission of the charged violation.
