What Does OUI Stand For?
OUI stands for Operating Under the Influence. It is the legal term Maine uses for what most other states call DUI (Driving Under the Influence) or DWI (Driving While Intoxicated), so the law defines OUI’s legal meaning similarly. Under Maine law, a person commits OUI when they operate or attempt to operate a motor vehicle while under the influence of intoxicants or with a blood alcohol concentration (BAC) of 0.08% or higher.
OUI vs. DUI: What Is the Difference?
OUI and DUI describe the same crime – driving drunk or impaired. The terms come from different state statutes. Maine’s key distinction is the word “operating” instead of “driving.” Under Maine case law, “operating” has a broader meaning.
A person can face OUI charges even while parked with the engine running. They must be in physical control of the vehicle. Most DUI states require the vehicle to be in motion.
Different states use different acronyms for this offense:
- DUI (Driving Under the Influence) – used in California, Florida, Arizona, and most other states
- DWI (Driving While Intoxicated) – used in Texas, New York, and New Jersey
- OWI (Operating While Intoxicated) – used in Wisconsin, Indiana, and Iowa
- OUI (Operating Under the Influence) – used in Maine, Massachusetts, and Rhode Island
These charges all target the same conduct. They address operating a vehicle while impaired by alcohol or drugs.
People sometimes search for “oui oui” because the word “oui” means “yes” in French. The legal acronym OUI has nothing to do with the French language. It is simply shorthand for Operating Under the Influence. The acronym appears on Maine court documents, police reports, and criminal records.
Legal Definition of OUI in Maine
Under Maine law, the State must prove three elements to convict a person of OUI:
- The person operated or attempted to operate a motor vehicle.
- The vehicle was on a public way or in a parking area.
- The person was under the influence of intoxicants, or had a BAC of 0.08% or higher.
What “operating” means. Maine defines operating broadly. You do not need to be driving down the road. Sitting in the driver’s seat with the keys in the ignition can meet the “operating” standard. Having the engine running while parked also qualifies. Courts look at whether you had the ability to make the vehicle move.
What counts as an intoxicant. An intoxicant under Maine law includes alcohol, illegal drugs, and prescription medications. Any substance that impairs your ability to operate a vehicle qualifies. A combination of substances also counts. You can face OUI charges even if you only took a lawfully prescribed medication.
The “under the influence” standard. The prosecution can prove impairment without a specific BAC reading. If your mental or physical abilities were compromised by an intoxicant, that is enough. A person with a BAC below 0.08% can still be convicted if the State shows impairment through field sobriety tests or officer observations.
Implied consent. Maine’s implied consent law requires drivers to submit to a chemical test when an officer has probable cause to believe they committed OUI. The test can measure breath, blood, or urine. Refusing the test triggers an automatic administrative license suspension separate from any criminal penalties. You have only 10 days after a refusal to appeal that suspension with the Bureau of Motor Vehicles.
What Are the Penalties for OUI in Maine?
Maine imposes escalating penalties based on prior OUI convictions and aggravating factors. All fines carry a 20% surcharge plus additional court fees.
First offense – Class D misdemeanor. Minimum $500 fine, 150-day license suspension, and up to 364 days in jail. A mandatory 48-hour jail sentence applies if your BAC was 0.15% or higher or you refused a chemical test.
Second offense – Class D misdemeanor. Minimum $700 fine, 3-year license suspension, and a mandatory 7-day jail sentence.
Third offense – Class C felony. Minimum $1,100 fine, 6-year license suspension, and a mandatory 30-day jail sentence.
Fourth and subsequent offenses – Class C felony with escalating penalties, longer suspension periods, and increased mandatory jail time.
Several aggravating factors increase the severity of any OUI charge:
- BAC of 0.15% or higher
- A passenger under 21 years old in the vehicle
- Exceeding the speed limit by 30 mph or more
- Causing an accident that results in serious bodily injury or death
- Prior OUI convictions from any state
A conviction carries real-world consequences beyond fines and jail. Employment, insurance rates, and personal records can suffer for years.
What Happens After an OUI Arrest in Maine?
Understanding the process after an arrest helps you make informed decisions at each stage.
Booking and release. After arrest, you will be transported to a police station for booking. This includes photographs, fingerprints, and a chemical test request. Most people are released on personal recognizance or after posting bail.
Administrative license suspension. The Bureau of Motor Vehicles handles license suspensions separately from the criminal case. If you failed a chemical test or refused one, your license suspension begins automatically. You must file an appeal within 10 days to challenge this suspension.
Arraignment. You will receive a court date for arraignment in Maine District Court. At arraignment, the judge reads the charges and you enter a plea. In our experience handling OUI cases in Southern Maine courts – including Portland, Biddeford, and Springvale – arraignment typically occurs within a few weeks of arrest.
Timeline. An OUI case can take anywhere from a few months to over a year to resolve. The timeline depends on the complexity of the evidence, whether you challenge the charges at trial, and the court’s schedule.
Common Defenses to OUI Charges in Maine
An OUI charge does not automatically lead to a conviction. Several defenses may apply depending on the facts of your case.
Challenging the traffic stop. An officer must have reasonable articulable suspicion to pull you over. If the stop lacked legal justification, any evidence gathered afterward may be suppressed. We have successfully challenged traffic stops in cases across Southern Maine courts.
Field sobriety test issues. Standardized field sobriety tests must follow strict protocols. Medical conditions, uneven road surfaces, poor lighting, and footwear can all affect test results. Improperly administered tests may not be reliable evidence of impairment.
Breathalyzer and chemical test challenges. Breath testing devices require regular calibration and proper operation. Calibration errors and operator mistakes can be challenged. The rising BAC defense also applies – your BAC may have been climbing at the time of the test and actually below 0.08% when you were driving.
Lack of “operating.” If you were not actually operating or attempting to operate the vehicle, the State cannot prove a critical element of OUI. This defense applies in cases where someone was sleeping in a parked car or sitting in the vehicle without the engine running.
Medical conditions. Certain conditions like diabetes, neurological disorders, and inner ear problems can mimic signs of impairment. These conditions may explain poor performance on field sobriety tests.

Frequently Asked Questions
Is an OUI the same as a DUI in Maine?
OUI and DUI describe the same offense – operating a vehicle while impaired by alcohol or drugs. Maine uses the term OUI (Operating Under the Influence) instead of DUI because its statute focuses on “operating” rather than “driving.” The legal consequences are the same as what other states call DUI or DWI.
Can you get an OUI in Maine without being over the legal limit?
A conviction is possible even if your BAC is below 0.08%. Maine law allows a conviction based on impairment alone. If the prosecution can show that your mental or physical abilities were affected by any intoxicant, you could face a conviction regardless of your BAC reading.
What happens if you refuse a breathalyzer test in Maine?
Refusing a chemical test triggers an automatic administrative license suspension under Maine’s implied consent law. A first refusal results in a 275-day suspension. You also face a mandatory 48-hour jail sentence and a $600 fine if convicted of OUI. The refusal can be used as evidence against you in court.
Is a first-offense OUI a felony in Maine?
A first-offense OUI is a Class D misdemeanor in Maine, not a felony. However, a third offense is a Class C felony, as is any OUI that causes serious bodily injury or death. Prior convictions from any state count toward your total.
How long does an OUI stay on your record in Maine?
An OUI conviction stays on your criminal record permanently in Maine. No expungement exists for OUI convictions under current Maine law. For penalty escalation purposes, Maine counts prior OUI convictions within the past 10 years to determine whether a new charge is treated as a second, third, or subsequent offense.
