Can a DUI be expunged in Montana?

Montana allows a DUI conviction to be cleared by misdemeanor expungement after 5 years from completion of the sentence, on conditions the statute sets. By petition only. The licensing agency keeps the DUI on the driver record either way.

A DUI conviction is the offence most often written out of a state's expungement law. Where relief exists at all it usually arrives with a waiting period, a one-time limit and a list of disqualifiers, and clearing the court record is not the same as clearing the record the licensing agency keeps. The rules below are Montana's own, each quoted from the statute or the agency that holds the record.

Also called: expungement of records; order of expungement.

How it is obtainedBy petition only

Montana's misdemeanor expungement law lets a person convicted of one or more misdemeanors petition a district court to expunge the records, once in a lifetime. A misdemeanor DUI is not barred, but Mont. Code Ann. § 46-18-1108 removes the presumption in favor of expungement for driving under the influence, so the district court decides after weighing the petitioner's age at the time of the offense, the time since the offense, rehabilitation, and the likelihood of reoffending. The law covers misdemeanors only, so a felony DUI is outside it.

Expungement may not be presumed if the person seeking expungement has one or more convictions for assault under 45-5-201, partner or family member assault under 45-5-206, stalking under 45-5-220, sexual assault under 45-5-502, a violation of a protective order under 45-5-626, or driving under the

The driving record is a separate record

This is the part most summaries leave out. A court can seal or expunge the criminal case and the licensing agency can still keep the DUI on the driver record, where it reaches insurers and counts as a prior offence if there is a second one.

Not cleared. An expungement order under Mont. Code Ann. § 46-18-1110 reaches records of arrest, investigation, detention and court proceedings held by the arresting agency, the prosecutor, the clerk of court and the Department of Justice. It does not reach the driving record. The Motor Vehicle Division describes the Montana driver record as a lifetime driving history and states that traffic convictions stay on it for life, and Mont. Code Ann. § 61-11-102 requires the record to include all convictions reported to the department.

How long the wait is, and from when

Expungement is presumed when the petitioner has no conviction in any state or federal court for 5 years after completing the sentencing terms, including payment of financial obligations and completion of court-ordered treatment, and has no pending charges. The 5-year timing requirement may be waived for a petitioner applying to a U.S. military academy or to enlist, or serving in the armed forces or national guard and held back by the conviction. Because a DUI removes the presumption, meeting the 5 years does not by itself decide the petition.

Whether a cleared DUI still counts as a prior

Mont. Code Ann. § 61-8-1011 counts a prior DUI conviction for sentencing when less than 10 years separate the present offense from the earlier conviction, and on a third or subsequent offense all previous convictions must be used. The same section bars a court from deferring imposition of sentence for a DUI, so Montana offers no deferred-sentence route that avoids a DUI conviction.

An offender is considered to have been previously convicted for the purposes of sentencing if less than 10 years have elapsed between the commission of the present offense and a previous conviction unless the offense is the offender's third or subsequent offense, in which case all previous

Code Ann. § 46-18-1107, expungement is presumed when 5 years have passed since the sentencing terms were completed, including payment of financial obligations and completion of court-ordered treatment, with no new conviction and no pending charges. The 5-year requirement may be waived for certain military applicants and service members. Montana allows a person to petition only once in a lifetime.
