The period of revocation, suspension, or disqualification shall begin on the date ordered by the court, on the date specified in the notice from the department, or on the date the suspension order is effective for failure to comply with a citation, whichever date is earlier. At the expiration of the period of revocation, suspension, or disqualification, a person may make application for license reinstatement as provided by law and shall pay a reinstatement fee, plus any application fees imposed by § 32-12A-15. A person making application following a revocation shall fulfill all knowledge examination requirements of a new applicant. A person making application for a commercial learner's permit or commercial driver license following a disqualification shall fulfill all examination requirements of a new applicant.
