   • Certificate (form DR 2598) or Discharge Referral Summary (DRS) for a Level II Education and Therapy program showing completion of courses or an Affidavit of Enrollment (form DR 2643)

Note: The Certificate or DRS requirement is determined by the associated BAC or the number of alcohol violations on your record (Multiple offenders or BAC of 0.17 and above requires Level II DRS or Affidavit of Enrollment).

When possible, you should mail the complete set of documents together to ensure that your reinstatement is processed in a timely manner.
