Maine OUI Penalties: Fines, Jail Time, and Suspension for a First Offense

Standard First-Offense Penalties

A first-offense OUI in Maine without aggravating factors is a Class D misdemeanor under 29-A M.R.S.A. § 2411. The statutory maximum is 364 days in jail, one year of probation, and a $2,000 fine — but the actual mandatory minimums for a clean first offense are considerably less severe:

• Fine: $500 minimum, plus a 20% state surcharge ($100) and a $65 court fee — bringing the total court cost to $665
• Jail time: Zero. A standard first offense carries no mandatory jail sentence
• License suspension: 150 days (from both the BMV administrative track and the court, running concurrently)
• DEEP program: Mandatory completion of the 20-hour Driver Education and Evaluation Programs course ($300 for adults 21+)
• BMV reinstatement fee: $50

The total financial impact — including towing, bail, DEEP, potential interlock costs, and insurance increases — typically runs between $3,400 and $6,500 depending on the pathway you take to restore your license.

When Jail Time Becomes Mandatory

While a standard first-offense OUI carries no mandatory jail sentence, four aggravating factors trigger a mandatory minimum of 48 hours of incarceration:

1. BAC of 0.15% or higher — a blood or breath alcohol concentration nearly double the legal limit
2. Excessive speed — operating 30 miles per hour or more over the posted limit at the time of the stop
3. Eluding an officer — attempting to evade law enforcement during the traffic stop
4. Passenger under 21 — having anyone under 21 years old in the vehicle

Each of these factors independently triggers the 48-hour jail minimum. They can also compound: a BAC of 0.15% with a minor passenger means the court sees two aggravating factors, though the minimum remains 48 hours for a first offense.

The passenger-under-21 aggravator carries an additional penalty beyond jail time — an extra consecutive 275-day license suspension (180 days if the driver is under 21), stacked on top of the standard court suspension.

Chemical Test Refusal: A Different Penalty Structure Entirely

Refusing the breathalyzer or blood test does not help you avoid penalties — it triggers its own, harsher set:

• Jail time: Mandatory minimum of 96 hours (four days), regardless of whether any aggravating factors are present
• Fine: $600 minimum (compared to $500 for test-takers)
• Administrative suspension: 275 days (compared to 150 days for test-takers)
• Suspension stacking: The 275-day administrative suspension and the 150-day court suspension run consecutively, not concurrently — totaling 425 days without a license
• No work-restricted license eligibility — § 2503 requires a chemical test submission
• No ignition interlock early reinstatement — the IID program is unavailable for refusal cases

The refusal penalty structure is severe enough that it changes the entire calculus of the case. If you refused the chemical test, consulting a defense attorney is strongly advisable to evaluate whether the officer properly administered the implied consent warnings — a procedural failure there can potentially lift the refusal suspension.

How the Class D Misdemeanor Classification Affects You

A Class D misdemeanor sits one class above Maine's lowest criminal classification (Class E). It is still a criminal conviction that creates a permanent record unless the case is dismissed or reduced. Key implications:

• It appears on criminal background checks
• Maine does not currently allow expungement of OUI convictions
• A conviction within 10 years counts as a prior offense if you are arrested for OUI again — and second-offense penalties escalate dramatically (mandatory minimum 7 days in jail and a 3-year license revocation)

The 10-year lookback period is why the first-offense outcome matters long-term. A conviction that seems manageable today becomes a significant liability if a second incident occurs within a decade.

Understanding Your Full Exposure

The penalties listed above are the floor, not the ceiling. Judges have discretion up to the Class D maximum, and prosecutors weigh the totality of circumstances when negotiating plea offers. Mitigating factors — a clean driving record, prompt enrollment in DEEP, voluntary substance evaluation — can work in your favor at the dispositional conference.
