Maine OUI Laws: 2025 DUI Charges Guide
Maine refers to alcohol-impaired driving as Operating Under the Influence (OUI) rather than DUI or Driving Under the Influence. The state implements a comprehensive system of penalties that escalate with repeat offenses and offers specific pathways to license reinstatement through ignition interlock devices and mandatory education programs.

Getting Started
If you’re arrested for OUI in Maine, you face both administrative penalties through the Bureau of Motor Vehicles (BMV) and criminal charges in court. While these proceedings are separate, both can significantly impact your driving privileges and personal freedom. This guide provides general information about Maine’s OUI laws, but it’s essential to consult with a qualified OUI attorney for advice specific to your situation.
Important Note: : While this page provides detailed information, DUI.org does not offer legal advice. Laws can change, so consult a qualified Maine OUI attorney for personalized guidance.
Definitions to Know
OUI (Operating Under the Influence)
Maine’s legal term for driving while impaired by alcohol or drugs.
SR-22
A certificate of financial responsibility filed by your auto insurer proving you maintain the minimum required liability insurance coverage after an OUI conviction.
IID (Ignition Interlock Device)
A breathalyzer installed in your vehicle that prevents it from starting if alcohol is detected on your breath.
Maine Bureau of Motor Vehicles (BMV)
The Bureau of Motor Vehicles handles administrative license suspensions, restricted license applications, and monitors compliance with OUI requirements. The BMV’s administrative process operates independently from the court system, so you could face license suspension even before your court date. The BMV oversees license reinstatement procedures and monitors IID program compliance for qualified drivers.

OUI Laws in Maine
What Are the Legal Driving Alcohol Limits in Maine?
Any additional OUI or driving violations while on probation or with a restricted license can result in severe penalties, including mandatory jail time and extended suspensions.
Driver Category | Legal BAC Limit |
Drivers over 21 | 0.08% or higher |
Commercial Drivers | 0.04% or higher |
Drivers under 21 | 0.00% (zero tolerance) |
Felony vs Misdemeanor OUI charges
In Maine, most first and second OUI offenses are classified as misdemeanors, while more serious cases are prosecuted as felonies. An OUI becomes a felony under specific circumstances that demonstrate heightened risk to public safety.
Misdemeanor OUI cases typically involve first or second offenses without aggravating factors. These are handled in District Court and carry shorter jail sentences (up to one year) and lower fines. Felony OUI charges apply to third or subsequent offenses within a 10-year period, or cases involving serious injury or death. These felonies are prosecuted in Maine’s Superior Court and carry potential prison sentences of several years, much higher fines, and longer license suspensions.
What Are Drunk Driving Diversion Programs in Maine?
Maine does not offer formal pre-conviction diversion programs specifically for OUI offenses like some other states. However, drivers with a first-time OUI may benefit from completing the state’s Driver Education and Evaluation Program (DEEP), which can satisfy court requirements. This is not a true diversion program as it typically occurs after conviction rather than as an alternative to prosecution.
For repeat offenses, Maine law focuses on rehabilitation alongside punishment through mandatory substance abuse evaluations and treatment programs administered by the Department of Health and Human Services. These programs aim to address underlying substance use issues while still holding drivers accountable through the traditional court process.
Refusing a Chemical Test Under Maine OUI Law
Maine, like all states, operates under implied consent law. By driving on Maine roads, you implicitly agree to chemical testing if an officer has probable cause to believe you’re impaired. Refusing a test carries administrative penalties independent of any OUI conviction.
Offense | Refusal Penalty |
First Refusal | 275-day license suspension |
Second Refusal | 18-month license suspension |
Third Refusal | 4-year license suspension |
Fourth Refusal | 6-year license suspension |
Additionally, if you’re convicted of OUI despite refusing the test, the court will consider the refusal as an aggravating factor when determining your sentence.
OUI Penalties & Consequences
Penalties for OUI Offenses in Maine
Penalties for OUIs in Maine become progressively severe with each conviction, especially for offenses occurring within a 10-year lookback period.
First Offense
Jail Time: 48 hours to 364 days
Fines: $500 minimum
License Suspension: 150 days
First Offense (BAC 0.15%+)
Jail Time: 48 hours minimum
Fines: $500 minimum
License Suspension: 150 days
Second Offense (within 10 years)
Jail Time: 7 days to 1 year
Fines: $700 minimum
License Suspension: 3 years
Third Offense (within 10 years)
Jail Time: 30 days to 5 years
Fines: $1,100 minimum
License Suspension: 6 years
Fourth Offense (within 10 years)
Jail Time: 6 months to 10 years
Fines: $2,100 minimum
License Suspension: 8 years
Aggravating Factors That Increase Maine OUI Penalties
In Maine, aggravating factors lead to:
- Elevated criminal charges
- Harsher fines
- Longer jail or prison time
- Extended license suspensions
- Additional requirements
Having a high BAC level (0.15% or higher) triggers enhanced penalties including mandatory minimum jail time even for first offenses. Refusing a chemical test automatically extends license suspension periods and can be used as evidence of guilt in court.
Driving with a passenger under 21 years old results in additional mandatory jail time and heightened scrutiny from the court. Causing an accident, especially those resulting in property damage, injury, or death, dramatically increases penalties and may trigger felony charges regardless of prior history. Prior OUI convictions within a 10-year period exponentially increase all penalties, with third and subsequent offenses treated as felonies with mandatory minimum jail sentences.
Driving Without a Valid License
Driving while your license is suspended due to an OUI conviction in Maine is a serious offense with severe consequences that extend far beyond a simple traffic ticket. If caught, you face mandatory minimum jail sentences starting at seven days for a first violation, with longer sentences for subsequent offenses. Fines for this violation start at $600 and increase substantially for repeat offenses.
The courts show little leniency for these violations because they demonstrate willful disregard for court orders and public safety. Additionally, driving while suspended will extend your original suspension period, potentially add points to your driving record, and may result in vehicle impoundment. These penalties apply even if you’re driving for what you consider essential purposes.
License Suspension
Who Determines if You Can Continue Driving After an OUI
In Maine, two separate entities determine your driving privileges after an OUI arrest, creating a dual-track system of penalties. The Bureau of Motor Vehicles (BMV) handles administrative suspensions that take effect shortly after arrest, regardless of court outcomes. These administrative suspensions occur if you fail a chemical test (BAC of 0.08% or higher) or refuse testing.
The court system imposes additional license suspensions as part of criminal sentencing if you’re convicted of OUI. These two suspension processes operate independently, though they may be served at the same time in some cases. The BMV focuses on immediate public safety concerns based on chemical test results, while the court imposes punitive measures based on criminal conviction.
How Long Will Your License Be Suspended?
Getting your license suspended in Maine means you are no longer allowed to drive a vehicle unless you obtain a temporary or restricted license during your suspension. Here’s how long your regular license may be suspended for an OUI in Maine:
Offense | Administrative and/or Court-Imposed Suspensions |
First Offense | 150 days |
Second Offense (within 10 years) | 3 years |
Third Offense (within 10 years) | 6 years |
Fourth Offense (within 10 years) | 8 years |
Steps to Reinstate Your License
To reinstate your driver’s license after an OUI suspension in Maine, you must complete several mandatory steps:
- Serve your full suspension period completely.
- Pay reinstatement fees ($50-$200, depending on circumstances).
- Complete the required Driver Education and Evaluation Program (DEEP).
- For early reinstatement install an IID if approved by court or BMV order.
- Provide proof of completion for all required programs to the BMV.
Restoring Your Driving Privileges
Eligibility for an Employment/Program-Restricted Driver’s License
Maine offers restricted licenses that allow limited driving privileges typically for employment, education, treatment programs, or medical appointments. To be eligible, you must have served a portion of your suspension period (usually at least half for first-time offenses). In order for drivers with their first OUI to qualify for certain programs, you must have no prior OUI convictions within the past 10 years.
The BMV requires installation of an IID in any vehicle you operate and proof of enrollment in or completion of alcohol education or treatment programs.
How to Apply for a Restricted Driver’s License
To apply for a restricted license in Maine, you must complete several required steps:
- Install an IID on your vehicles (using an approved provider).
- Submit an application form to the Maine BMV.
- Provide documentation of need (e.g., employment verification or medical necessity).
- Pay applicable fees, including a reinstatement fee.
- Provide proof of completion or enrollment in required education programs.
Maine Ignition Interlock Device (IID) Requirements
Maine’s ignition interlock program allows certain drivers convicted of OUI to regain limited driving privileges by installing an IID that prevents the vehicle from starting if alcohol is detected on your breath. The program requires installation in all vehicles you operate. You must comply with regular IID calibration appointments. The device records all test results and vehicle usage, which are monitored by the BMV.
The required IID period varies based on your offense: first-time OUI offense is a 150-day suspension, but may be able to reduce the suspension to 30 days with installation of an IID and maintain limited driving privileges, while repeat offenses face longer required periods. For drivers with a second OUI conviction, the IID period is one year after serving part of the suspension; for third offenses, it extends to two years after serving part of the suspension.

Selecting the right ignition interlock provider can make a world of difference.
SR-22 Insurance Requirements
After an OUI conviction in Maine, the Maine Bureau of Motor Vehicles (BMV) may, in certain instances, require proof of insurance before reinstating a license after an OUI suspension. If an SR-22 filing is required, it would typically need to be maintained for several years following license reinstatement, and any lapse in coverage would result in a new license suspension.

Substance Abuse Evaluation and Treatment
Maine requires all drivers convicted of OUI to complete the Driver Education and Evaluation Program (DEEP) administered by the Office of Behavioral Health. This comprehensive program begins with a substance use evaluation to determine the appropriate level of intervention. The basic program includes risk reduction education sessions designed to prevent future impaired driving.
Based on evaluation results, you may be required to complete additional treatment ranging from short-term educational interventions to more intensive counseling or substance use disorder treatment. The BMV requires verification of program completion before reinstating driving privileges, regardless of whether you’ve served your full suspension period. Program costs vary based on the required level of intervention but typically start at several hundred dollars for the basic program, with additional costs for any required treatment.

Understand what to expect and how to prepare for a substance abuse evaluation.
FAQs About OUIs in Maine
What is the difference between OUI and DUI in Maine?
There is no difference in meaning; Maine legally uses the term OUI (Operating Under the Influence) while many other states use DUI or DWI. All refer to operating a vehicle while impaired by alcohol or drugs.
Can you refuse a breathalyzer test in Maine?
Yes, but refusing carries automatic license suspension penalties (275 days for first refusal) that are often longer than those for failing the test, and refusal can be used against you in court.
Will you lose my commercial driver’s license (CDL) after an OUI in Maine?
Yes. Even a first-offense OUI results in a one-year CDL disqualification, and if you were driving a commercial vehicle at the time, the disqualification extends to three years.
Do you need to install an IID for a first OUI offense in Maine?
It’s not mandatory for first-time OUI convictions with no aggravating factors so you may choose to install one to obtain limited driving privileges during your suspension period.
How long does an OUI stay on your record in Maine?
OUI convictions remain on your driving record for 10 years for purposes of calculating penalties for subsequent offenses. However, they remain on your criminal record permanently.
