After a misdemeanor DUI arrest in Montana, you will almost always be released, either on your own recognizance or after posting bail, and usually with conditions. Montana law makes every person bailable before conviction except where death is a possible punishment (MCA § 46-9-102), and it directs courts to authorize release on reasonable conditions (MCA § 46-9-106). This page, part of our Montana DUI Guide, explains how release is decided, what conditions are common, and what a violation does.
Two Routes Out of Jail
Under a bail schedule.A judge may establish and post a schedule of bail for offenses within that court's jurisdiction, and a peace officer may accept bail on the judge's behalf in accordance with it (MCA § 46-9-302(1), (2)(a)). Where a court has a schedule that covers DUI, a person can post the listed amount and be released with a date to appear. The officer must give you a signed receipt for the bail (MCA § 46-9-302(3)). Whether a schedule exists, and the amounts on it, differ from court to court. We do not print figures here because they are local and they change.
Before a judge. Otherwise, an arrested person must be taken before a judge without unnecessary delay (MCA § 46-7-101(1)). The statute does not state a number of hours. Release or detention must be determined immediately at that initial appearance (MCA § 46-9-109(1)). How long a jail holds a person before release, including any time to sober up, is a matter of local jail practice rather than a number in the bail statutes.
Release on Your Own Recognizance
Release on personal recognizance means no money is posted. You are released on your promise to appear, subject to conditions (MCA § 46-9-111). The court must fully tell you the penalty for failing to comply. That warning has teeth: Montana's bail-jumping statute generally does not reach misdemeanor cases, but it does apply when the judge released the defendant on the defendant's own recognizance (MCA § 45-7-308(3)). Our page on a missed court date explains that offense.
How a Judge Decides
In deciding release, the court takes into account the nature of the offense, your character, family and community ties, employment, financial resources, past conduct, history relating to alcohol or drug abuse, criminal history, and record of appearing in court. It also considers whether you were on probation or pretrial release at the time (MCA § 46-9-109(2)). When money bail is set, the amount must be reasonable, sufficient to ensure your presence, not oppressive, commensurate with the offense, and considerate of your financial ability and prior record (MCA § 46-9-301).
In a DUI case, the facts that tend to change the picture are a prior DUI, a crash, a very high test result, or an existing release order in another case. See our pages on second and third DUI and aggravated DUI.
The Forms Bail Can Take
| Form | What it is | MCA |
|---|---|---|
| Cash or other approved property | A deposit with the court equal to the required bail. It is returned when the conditions of bail have been performed and you are discharged from the case. | §§ 46-9-401(1)(a), 46-9-502 |
| Real estate | Montana property with unencumbered equity worth double the required bail. | § 46-9-401(1)(b) |
| Written undertaking | A written promise signed by you and two sufficient sureties. | § 46-9-401(1)(c) |
| Commercial surety bond | A bond posted by a bail bond company. It is an appearance bond only and cannot be forfeited for fines or for violations other than failing to appear. | §§ 46-9-401(1)(d), 46-9-503(5) |
Bail must ensure your appearance at every stage of the case and, unless the court orders otherwise, stays in effect until final sentence is pronounced (MCA § 46-9-401(2)).
Common Conditions in a DUI Case
The court may impose any condition that will reasonably ensure your appearance or the safety of any person or the community (MCA § 46-9-108(1)). These are the listed conditions that come up most in DUI cases:
| Condition | MCA |
|---|---|
| Commit no new offense while released | § 46-9-108(1)(a) |
| No use or possession of alcohol, or of drugs without a legal prescription | § 46-9-108(1)(i) |
| An alcohol monitoring device, such as a transdermal unit or a facial recognition breath unit | § 46-9-108(1)(i) |
| Limits on travel, where you live, or who you associate with | § 46-9-108(1)(d) |
| Regular reporting to a pretrial services agency or another designated person | § 46-9-108(1)(f) |
| A chemical dependency or mental health treatment program | § 46-9-108(1)(j) |
| The 24/7 sobriety program, for an aggravated DUI or a second or later violation | § 44-4-1205(2)(a) |
Two limits apply. The court may not impose an unreasonable condition that results in pretrial detention, and it must use the least restrictive condition or combination of conditions that will do the job (MCA § 46-9-108(3)). And the conditions must be written down: a release order must include a written statement of any restrictions (MCA § 46-9-110). If you were told something in court that is not on the paper, or the reverse, ask your lawyer which controls before you rely on it.
Monitoring conditions have their own page: pretrial alcohol monitoring. The 24/7 program is described on our 24/7 sobriety program page.
If a Condition Is Violated
A violation of a release condition, including a failure to appear, lets the prosecutor move to revoke the release order, and a judge may issue an arrest warrant (MCA § 46-9-503(1)). If bail was posted and you fail to appear, the judge may declare it forfeited (MCA § 46-9-503(2)). After an arrest for a violation, you must be brought before the court without unnecessary delay, and the court holds a hearing and determines bail again (MCA § 46-9-505(4)). That new decision can mean a higher amount or tighter conditions.
A new offense while on release is itself a violation of the most common condition, and the court will consider that you were on release when deciding what to do next (MCA § 46-9-109(2)(b)(ii)).
Asking the Court to Change Bail or a Condition
Bail is not fixed for the life of the case. On application by the State or the defendant, with reasonable notice to the other side, the court may increase or reduce the amount, substitute one form of bail for another, alter the conditions, or revoke bail (MCA § 46-9-311). The court may also amend conditions at any time on a reasonable basis (MCA § 46-9-108(3)), and the reasonableness of bail is one of the listed topics for the omnibus hearing (MCA § 46-13-110(3)(k)).
Requests that tend to be worth making are specific and documented: a work schedule that conflicts with testing times, a need to travel for a job, or a medical issue. The first chance to raise them is usually the arraignment.
