A DUI sentencing hearing is the court date, after a guilty plea or a guilty verdict, where the judge hears from both sides and imposes the sentence. Montana law fixes part of that sentence in advance: a jail range, a fine range, and an assessment with an education course or treatment. The hearing decides the rest, including how much jail is suspended and on what conditions. This page is part of our Montana DUI Guide and expands the sentencing stage of the DUI court process.

When Sentencing Happens

If the verdict or finding is guilty, "sentence must be pronounced and judgment rendered within a reasonable time" (MCA § 46-18-102(3)(a)), and the sentencing hearing must be held "without unreasonable delay" (MCA § 46-18-115). Neither statute gives a day count.

In a misdemeanor DUI resolved by a plea agreement, sentencing commonly takes place at the same hearing as the plea. After a trial, or where the judge wants more information, it may be set for a later date. A formal presentence investigation by a probation officer is a felony procedure: the statute provides for one on a plea or verdict of guilty to a felony offense (MCA § 46-18-111(1)(a)(i)).

What Happens at the Hearing

MCA § 46-18-115 sets the structure:

  1. Both sides are heard. The court must give the parties an opportunity to be heard "on any matter relevant to the disposition," including whether a mandatory minimum applies.
  2. You may speak. The court must address you personally "to ascertain whether the defendant wishes to make a statement and to present any information in mitigation of punishment."
  3. A victim may speak. If the offense had a victim, as in a crash case, the court must permit a statement about the effects of the crime and the victim's opinion on the sentence. If the statement includes new material facts the court intends to rely on, you must be given an adequate opportunity to respond.
  4. The court imposes sentence. When the sentence is pronounced, the judge must clearly state the reasons for it on the record (MCA § 46-18-102(3)(b)).

If there is a plea agreement, the prosecutor makes the agreed recommendation at this point. Whether the judge has to follow it depends on the type of agreement.

What the Judge Must Impose

ComponentThe ruleMCA
Jail within the statutory rangeThe range depends on the subsection and the offense number. Where there is a mandatory minimum, it cannot be suspended or served on home arrest unless the judge finds jail would pose a risk to your physical or mental well-being.§ 61-8-1007(1)(d), (2)(d), (4)(b)
A fine within the statutory rangeThe DUI statute sets a minimum and maximum. A general sentencing statute also says a judge may not sentence a person to pay a fine unless the person is or will be able to pay it.§§ 61-8-1007, 46-18-231(3)
Assessment, plus a course or treatmentA chemical dependency assessment, and an education course or treatment, regardless of disposition.§§ 61-8-1007(5), 61-8-1009(1)
No deferred sentenceThe court may not defer imposition of sentence for a DUI.§ 61-8-1011(4)
Monitoring, interlock, or forfeiture on a repeat offenseOn a second or later conviction the court must order one of three options.§ 61-8-1010(2)

The ranges differ by charge. For example, a first impairment DUI carries 24 consecutive hours to 6 months in jail and a fine of $600 to $1,000, while the statute for a first per se DUI states a maximum of 6 months and no minimum jail term (MCA § 61-8-1007(1)(a)(i), (2)(a)(i)). The full set of ranges is on our DUI penalties chart.

Where the Judge Has Discretion

Suspending jail above the minimum. The remainder of the jail sentence "may be suspended for a period of up to 1 year pending the person's successful completion of a chemical dependency treatment program" (MCA § 61-8-1007(1)(e)). During the suspended portion you are subject to the conditions the court sets, which can include a drug or DUI court and the 24/7 sobriety program where available. If you violate a condition, the court may impose the suspended time. See suspended sentences explained.

Where the time is served. The court may order jail time served in another facility made available by the county, and, subject to the limits on mandatory minimums, may allow time under home arrest (MCA § 61-8-1011(2), (3)).

The fine within the range, and payment. In setting the amount and method of payment, the judge must take into account the nature of the crime, your financial resources, and the burden that payment will impose (MCA § 46-18-231(3)). The same ability-to-pay rule applies to costs (MCA § 46-18-232(2)).

The probationary license recommendation. On a first offense, the court may recommend a probationary license and may attach conditions such as monitoring or an ignition interlock (MCA § 61-8-1010(1)). On a second or later offense, a probationary license is not available until part of the suspension has been served and requires the court's recommendation (MCA § 61-5-208(2)(b)). See ignition interlock and probationary licenses.

What the Judge Considers

Montana's sentencing policy directs courts to punish commensurate with the harm caused, protect the public, provide restitution to victims, and "encourage and provide opportunities for the offender's self-improvement" (MCA § 46-18-101(2)). It also says sentencing practices must permit judicial discretion to consider aggravating and mitigating circumstances (MCA § 46-18-101(3)(d)).

In a DUI case, the facts that usually bear on those goals are the alcohol concentration or drug result, the driving, whether anyone was hurt, any prior record, how you have done on release conditions, and what the chemical dependency assessment recommends. The judge may require that assessment before sentencing, and if it is not done by then, must order it as part of the sentence (MCA § 61-8-1009(2)).

Preparing to Speak

Your statement is optional and it is yours. Judges generally respond to specifics over speeches: what you have done since the arrest, such as a completed assessment, a course or treatment already started, or clean monitoring results, and what your work and family obligations are. Documents carry more weight than assurances, so bring proof.

Two cautions. If you were convicted after a trial and may appeal, talk with your attorney before saying anything about the facts of the offense. And do not use the statement to argue with the verdict or the officer. That is for an appeal, not for sentencing.

After the Sentence Is Pronounced

The written judgment must be signed and entered within 30 days after the oral pronouncement. If the written judgment and the oral sentence conflict, either side may ask the court, within 120 days after the written judgment is filed, to conform the written judgment to what was said in court (MCA § 46-18-116(1), (2)). Read your written judgment when it arrives and compare it to your notes.

The court reports the conviction to the Motor Vehicle Division, which imposes the license suspension (MCA § 61-5-208(2)(b)). If you were convicted after a trial in a lower court, the notice of appeal is due within 10 days. See appealing to district court. For life under the sentence, see DUI probation conditions.
