Facing DUI Charges in Missoula? You’ve Found Your Defender.
At Maldonado Law, PLLC, we provide aggressive, strategic DUI defense for people in Missoula and throughout Western Montana. A DUI conviction can threaten your license, your job, and your freedom — but with the right defense, you can fight back. Whether you were pulled over downtown, near the university, or on Highway 93, we understand how Missoula DUI cases are prosecuted — and how to defend them.

Understanding DUI Charges
Charged with DUI in Missoula? You don’t have to face it alone.
In Montana, driving under the influence (DUI) means operating a vehicle while impaired by alcohol, drugs, or a combination of both. You can be charged with DUI if:
Your blood alcohol concentration (BAC) is 0.08% or higher
You’re under 0.08% but show signs of impairment
You’re under the influence of marijuana, prescription drugs, or other substances
Missoula law enforcement regularly conducts DUI patrols and checkpoints near downtown, the university, and major highways. We’ve defended many cases where legal medication or flawed testing led to an unjust charge.
“No matter the circumstances of your arrest, we’ll treat your case with the urgency and skill it deserves.” — Dave Maldonado, Missoula DUI Lawyer
You only have 30 days after your arrest to request a hearing with the Montana Motor Vehicle Division (MVD) at the Missoula DMV to prevent your license from being automatically suspended. Our team helps Missoula drivers:
- File the hearing request before the deadline
- Prepare for and attend your license suspension hearing
- Begin building your defense immediately
With over a decade of legal experience, our attorneys know how DUI laws are charged and enforced in Missoula County—and how to challenge them. From first-time offenses to felony DUIs, we’ve helped countless clients protect their rights and their futures.

Missoula law enforcement takes impaired driving seriously. DUI arrests are common near the University District, downtown bars, and along Brooks Street and Highway 93. Each case is handled by either the Missoula Municipal Court or Missoula County Justice Court, depending on jurisdiction. Our team is familiar with how local prosecutors operate and what strategies are most effective in Missoula courtrooms.
DUI Penalties in Montana
If you're convicted of DUI in Missoula, you could lose your license, face jail time, and carry a permanent mark on your record — affecting your ability to work or travel.
First DUI Offense (Misdemeanor)
- Fines: $300–$1,000
- Jail Time: Up to 6 months
- License Suspension: Up to 6 months
- Additional Penalties: Possible probation, mandatory alcohol education courses, or ignition interlock device
Second DUI Offense (Within 10 Years)
Repeat DUI offenses in Montana carry increasingly severe consequences. A second DUI within 10 years may result in 7 days to 1 year in jail, fines up to $1,000, a 1-year license suspension, and mandatory treatment programs. A third offense can lead to felony charges, up to 5 years in jail, fines of $5,000, and a minimum 3-year license suspension. These convictions come with long-term consequences, including increased court supervision, substance abuse monitoring, and a permanent criminal record.
When you drive on Montana roads, you automatically agree to submit to a chemical test—such as a breath, blood, or urine test—if law enforcement suspects you of driving under the influence. This is known as Montana’s Implied Consent Law.
Refusing to take a chemical test after a lawful DUI arrest can lead to serious consequences, even if you’re never convicted of DUI. These penalties may include:
- Automatic driver’s license suspension (typically 6 months or longer)
- Ineligibility for a probationary license
- Increased penalties if later convicted of DUI
- Use of your refusal as evidence in court
