National Criminal Defense Recognition, Applied to Your Maine OUI Case
Maine uses the term OUI (operating under the influence) rather than DUI, and the distinction matters. The “operating or attempting to operate” standard gives law enforcement broader arrest authority than a strict driving requirement. A driver with keys in the ignition or hands on the wheel may qualify for an OUI arrest under Maine law, even if the vehicle never moved. That legal reality makes the quality of your defense more consequential, not less.
An OUI arrest in Portland sets two separate proceedings in motion at once: a criminal case in court and an administrative license suspension through the Maine Bureau of Motor Vehicles. Both require immediate attention. At Zerillo Law Firm, we’ve served Portland and Cumberland County for over two decades. Tim Zerillo is the only lawyer in Maine elected to the American Board of Criminal Lawyers, a nomination-only national organization for the country’s top criminal trial attorneys. That national standing is what we bring to your traffic stop, your breathalyzer record, and your BMV hearing.

How Maine OUI Law Works
Maine law defines OUI across two tracks. A charge can rest on a BAC of 0.08% or higher alone, without any observed impairment. It can also rest entirely on observable impairment, even when BAC falls below the legal limit. Both paths lead to the same criminal charge.
The substances covered extend well beyond alcohol. Illegal drugs, prescription medications, and any combination of intoxicants fall within Maine’s OUI statute. For drivers under 21, Maine’s zero-tolerance law means any measurable alcohol in the system is a violation. The 0.08% threshold doesn’t apply to underage drivers.
Maine OUI Penalties by Offense Level
Penalties escalate sharply with each conviction, and Maine’s 10-year lookback period determines how prior convictions count toward enhanced charges. Only convictions within the preceding 10 years factor into offense level for sentencing purposes.
First Offense Penalties:
Minimum $500 fine and 150-day license suspension
No mandatory jail time unless aggravating factors are present
Aggravating factors include BAC of 0.15% or higher, a passenger under 21, speeding 30 or more mph over the limit, or eluding law enforcement; each triggers a mandatory minimum of 48 hours in jail
Minimum $700 fine, 7-day jail sentence, and 3-year license suspension
Third Offense (Class C felony):
Minimum $1,100 fine, 30-day jail sentence, and 6-year license suspension
OUI Causing Serious Bodily Injury (Class C crime):
Minimum 6 months incarceration, $2,100 fine, and 6-year license suspension
Mandatory minimums at this level can’t be suspended by the court
OUI Causing Death (Class B crime):
Minimum 6 months incarceration, $2,100 fine, and 10-year license suspension
Mandatory minimums at this level can’t be suspended by the court
The consequences extend beyond the courtroom. A conviction can affect professional licenses, appear in employment background checks, and, for commercial drivers, end CDL eligibility. Maine doesn’t permit expungement of OUI convictions; the record is permanent. The only post-conviction avenue is a petition to the Governor for Executive Clemency, which is rarely granted and doesn’t clear the record even if approved. For anyone facing a first OUI charge, knowing there’s no path to erasure is one reason to invest in the defense before a conviction occurs.
How We Build an OUI Defense
Every OUI case begins with the traffic stop, and that’s where defense work begins too. We examine whether law enforcement had probable cause to initiate the stop, whether standardized field sobriety tests were properly administered, and whether the breath-testing device was correctly calibrated and maintained. Breathalyzer calibration and maintenance records are recoverable, and discrepancies in those records can directly affect the reliability of the test result.
We also look closely at how implied consent advisements were delivered. If those advisements weren’t correctly given, the consequences for refusal may not legally apply. In cases involving blood samples, we review chain of custody and handling procedures for contamination issues. Where the evidence supports it, pretrial motions can result in suppression of breath or blood test results, substantially weakening the prosecution’s case before trial begins.
Tim Zerillo has chaired the NACDL’s Defending Modern Drug Cases seminar and has been recognized as a “Best of the Best” speaker by the National Association of Criminal Defense Lawyers in both 2022 and 2024. That national engagement directly informs how we approach impairment-based charges. When technical or medical questions arise, we draw on a network of investigators and medical professionals to support case preparation. We’ve secured dismissals on serious charges across a wide range of criminal matters, including cases where prosecutors maintained a defense win was impossible.

The BMV Administrative Hearing: Your 10-Day Window
When a Maine driver is arrested for OUI, the license suspension begins administratively, before any court appearance or conviction. This is a separate proceeding from the criminal case, governed by Maine’s implied consent law. The two tracks run simultaneously, and the outcome of one doesn’t determine the outcome of the other.
A driver must request a Bureau of Motor Vehicles hearing in writing within 10 days of receiving the suspension notice. Miss that window and the suspension becomes automatic. Requesting the hearing preserves the right to challenge the suspension and may allow driving privileges to continue while the hearing is pending.
At the BMV hearing, a defense attorney can challenge whether the arresting officer correctly administered the required implied consent advisements. A successful challenge may result in the suspension being overturned even while criminal charges remain pending. Refusal to submit to chemical testing carries its own administrative consequence: a 275-day suspension for a first refusal, which runs consecutive to any conviction-based suspension.
License Restoration After an OUI Suspension
Maine’s restoration pathway depends on the offense level, whether the driver refused chemical testing, and completion of required programs.
First-Offense Restoration Options
After a first offense, a driver may petition for early reinstatement with an ignition interlock device (IID). This is a breathalyzer installed in the vehicle that requires a clean breath sample before the car can start. This may be available after completing 30 days of hard suspension and satisfying the requirements of the Driver Education and Evaluation Program (DEEP). DEEP is a substance abuse evaluation and education program Maine requires before any license can be reinstated after an OUI conviction.
A work-restricted or hardship license may be available for first-offense drivers after a portion of the suspension is served, subject to DEEP completion. Refusal-based suspensions don’t qualify for a work-restricted license.
Second & Third Offense Timelines
For a second offense, IID eligibility begins after 9 months of suspension. For a third offense, that window extends to 3 years.
Maine reports all OUI suspensions and convictions to other states and Canadian provinces. Drivers licensed outside Maine may face additional consequences from their home state or province, separate from what Maine imposes.
OUI Convictions & Maine’s Permanent Record Rule
Maine eliminated the expungement of criminal records. An OUI conviction becomes part of the permanent record and will appear in background checks run by employers, landlords, and professional licensing boards. There’s no waiting period after which the record clears automatically.
The only avenue available after conviction is a petition to the Governor for Executive Clemency. That process is rarely initiated and even more rarely granted. More importantly, even a successful clemency petition doesn’t wipe the criminal record. The conviction remains visible; only its legal effect may change.
