Yes, if it is your only conviction. Under R.I. Gen. Laws ยง 12-1.3-2, a first offender can petition to expunge a misdemeanor, including a first-offense DUI, 5 years after completing the sentence, including probation and payment of fines, as long as there were no new convictions in that time. A second DUI, or a DUI on top of other convictions, generally cannot be expunged, because the separate route for people with several misdemeanors excludes DUI and refusal convictions. The Attorney General can object to a petition, and the judge decides whether expungement is in the interest of justice. If your case was dismissed or ended without a conviction, sealing may be available without the waiting period.
