Local DUI Laws

If you’re facing a DUI charge in Montana, one of the first questions you’ll likely have is: what happens next? The court process can feel confusing, especially if you’ve never been involved with the legal system before. Montana’s DUI court process follows a series of steps that begin shortly after arrest and may continue for several months, depending on how the case unfolds.

Understanding this process doesn’t just help you know what to expect—it also helps you make sense of the paperwork, court appearances, and procedures that follow. While this guide does not provide legal advice, it offers a complete overview of how DUI cases move from arrest to resolution within the Montana court system.

In this post, we’ll walk through each major phase of the DUI court process in Montana. From the initial arrest through arraignment, pretrial motions, potential plea deals, and trial, you’ll get a clear sense of how the state handles these cases and what each step involves.

Step 1: The DUI Arrest and Immediate Aftermath

The DUI court process begins at the moment of arrest. In Montana, officers typically initiate a traffic stop after observing suspicious driving behavior or a violation such as swerving, speeding, or running a stop sign. If impairment is suspected, officers may perform field sobriety tests or a breath test.

If probable cause is found, the driver is arrested and taken to a local jail or detention center. At this point, several things happen quickly:

• The vehicle may be towed or impounded
• A chemical test (breath or blood) may be administered
• Booking procedures begin (photograph, fingerprints, personal details)
• A Notice of Suspension may be issued for the driver’s license
• The driver may be held in custody until bail is posted or a release is granted

The arrest itself sets in motion both an administrative process (usually involving license suspension) and a criminal process that begins in court.

Step 2: Initial Court Appearance and Arraignment

The first official court proceeding after a DUI arrest in Montana is the initial appearance, also known as the arraignment. This usually occurs within a few days of the arrest, especially if the person remains in custody.

During this hearing, the following occurs:

• The judge informs the defendant of the charges
• The defendant is advised of their rights
• A plea is entered (usually “not guilty” at this stage)
• Bail conditions may be reviewed or set
• A future court date is scheduled

The arraignment is typically brief, but it’s an important step that marks the formal start of the court case. At this point, the case becomes part of the public court docket, and the legal process begins to unfold in earnest.

In Montana, most first-time DUI offenses are filed as misdemeanors, but aggravating factors can elevate the charge to a felony. Either way, the case moves through the appropriate court with its own calendar and deadlines.

Step 3: Pretrial Motions and Evidence Review

Once the arraignment is complete, the pretrial phase begins. This is where both the prosecution and defense prepare their cases. A large part of this phase involves discovery, where each side exchanges evidence and information.

Key elements of the pretrial phase in Montana include:

• Discovery Requests: The defense may request police reports, body camera footage, chemical test results, calibration records, and more
• Motions to Suppress: The defense may challenge the legality of the traffic stop, the arrest, or the chemical test procedure
• Motion Hearings: A judge may hear arguments about excluding evidence, challenging probable cause, or modifying bail conditions
• Negotiations: In some cases, the prosecution may offer a plea deal in exchange for a guilty plea to a reduced charge

This stage is also when the defense might request independent testing of blood samples or further analysis of breath test devices. Any errors in procedure or lapses in protocol discovered here can significantly affect the outcome of the case.

Step 4: Plea Bargains and Alternative Resolutions

Not every DUI case in Montana goes to trial. In fact, many are resolved through plea agreements during the pretrial phase. A plea bargain is an agreement between the defendant and prosecutor in which the defendant pleads guilty—usually to a lesser charge or with agreed-upon sentencing terms.

Common plea deal outcomes might include:

• Reduction of a DUI charge to reckless driving or another non-alcohol-related offense
• Agreement to participate in alcohol treatment or education programs
• Lower fines or reduced jail time
• No contest plea with agreed sentencing terms

Whether a plea deal is offered depends on multiple factors, including:

• The strength of the evidence
• Whether the defendant has prior DUI convictions
• The specific circumstances of the arrest
• Prosecutorial discretion

Plea bargains can resolve a case more quickly and with more predictable outcomes, but they are not guaranteed and are evaluated case by case.

Step 5: DUI Trial Process in Montana

If no plea deal is reached, the case proceeds to trial. DUI trials in Montana are typically held in city or county courts, and the defendant can choose a jury trial or bench trial (where a judge decides the outcome).

The trial process includes:

• Jury Selection (if applicable)
• Opening Statements from both sides
• Presentation of Evidence by the prosecution (including officer testimony, test results, body cam footage, etc.)
• Cross-Examination by the defense
• Defense Case (if presented)
• Closing Arguments
• Verdict: The judge or jury decides if the defendant is guilty or not guilty

If convicted, sentencing is usually scheduled shortly after. If acquitted, the case is dismissed, and no criminal penalties apply (though administrative penalties like license suspension may still be in place).

Trials are rare for first-time DUI charges but are more common in complex or contested cases.

Step 6: Sentencing and Penalties if Convicted

If the court finds the defendant guilty, either through plea or trial, sentencing follows. In Montana, penalties for DUI vary based on whether it is a first, second, or subsequent offense. Factors like BAC level, refusal to test, or the presence of minors in the vehicle can also influence sentencing.

Typical penalties for a first-time DUI conviction in Montana include:

• Jail Time: 24 hours to 6 months
• Fines: $600 to $1,000
• License Suspension: Usually 6 months
• Mandatory Alcohol Education or Treatment
• Possible Ignition Interlock Device Installation

Repeat offenses result in harsher penalties, including longer jail time, higher fines, and extended license revocation periods.

The sentencing phase also considers whether the defendant has completed any pretrial requirements or enrolled in alcohol education programs, which may influence outcomes.

Step 7: Post-Conviction Consequences and License Reinstatement

After sentencing, the court process ends, but the consequences may continue. Many DUI convictions in Montana carry long-term impacts, especially for driving privileges and background records.

Post-conviction outcomes may include:

• Loss of Driving Privileges: Extended license suspension or revocation
• Insurance Increases: Higher auto premiums or policy cancellations
• Permanent Criminal Record: DUI convictions remain on public records and can appear in background checks
• Ignition Interlock Requirements: Mandatory device installation as a condition of license reinstatement
• Probation Monitoring: Some sentences include supervised probation, especially for repeat offenders

Reinstating a driver’s license after suspension requires completing all court-ordered conditions, paying fees, and in some cases, retaking driving tests. The Montana Motor Vehicle Division handles this process separately from the court system.

A simple case may resolve in a few weeks if a plea deal is accepted. Contested cases that go to trial can take several months or longer.

Conclusion

The DUI court process in Montana follows a clear but multi-step path. After the arrest, drivers move through arraignment, pretrial motions, possible plea negotiations, and—if necessary—trial and sentencing. Along the way, the state evaluates evidence, enforces administrative penalties, and determines whether a conviction will follow.
