Cumberland County’s Only ABCL-Elected Attorney. Two Decades of OUI Defense.
A first offense OUI under 29-A M.R.S.A. section 2411 is a Class D misdemeanor, but the consequences extend well past a fine and a court date. Two separate proceedings begin immediately after an arrest: a criminal defense case and a Maine Bureau of Motor Vehicles administrative suspension action. Both require prompt attention, and the decisions made in the first few days shape what defense options remain.
Zerillo Law Firm has served clients throughout Cumberland County for over two decades. Tim Zerillo is the only attorney in Maine currently elected to the American Board of Criminal Lawyers, an invitation-only national organization that requires nomination and a vote from its membership. Same-day consultations are available, and you reach your attorney directly when you call.

First Offense OUI Penalties in Maine
At its baseline, a first offense OUI with no aggravating factors and no refusal carries a mandatory minimum $500 fine and a 150-day license suspension. There’s no mandatory jail time at this level. That changes when aggravating factors are present.
A mandatory minimum 48-hour jail sentence applies when any of the following are present: a BAC of .15 or higher, a passenger under 21 in the vehicle, operating at 30 mph or more over the posted speed limit, or attempting to elude law enforcement. The maximum sentence for a first offense OUI in Maine is 364 days in jail.
Refusing a chemical test carries its own consequences. A refusal after a first offense arrest raises the minimum fine to $600, adds a mandatory minimum of 96 hours in jail, and triggers a 275-day administrative suspension rather than 150 days.
One fact that surprises many clients: a conviction stays on the criminal record permanently. The 10-year lookback period determines only how a prior OUI counts toward sentencing on a future charge, not whether the record clears. A second OUI filed within 10 years carries a mandatory minimum 7-day jail sentence, a 3-year license suspension, and a $700 minimum fine.
The 10-Day BMV Deadline & Your Criminal Case
After a Portland OUI arrest, the Maine Bureau of Motor Vehicles can impose an administrative license suspension entirely separate from any court action. That suspension can take effect before your criminal case is resolved. To contest it, you must request a hearing within 10 days of the effective date of the suspension notice. Missing that window means the suspension proceeds without challenge.
Administrative Suspension Lengths
The suspension length depends on whether you submitted to testing. A breath test result triggers a 150-day administrative suspension. A refusal triggers 275 days. If you submitted to testing, the administrative and any court-ordered suspension generally run concurrently. If you refused, they run consecutively.
After serving 30 days of the suspension, a first-offense driver who submitted to chemical testing may be eligible for a restricted license by installing an ignition interlock device (IID) for the remainder of the suspension period, provided Driver Education and Evaluation Program (DEEP) requirements are met. Drivers whose suspension arose from a refusal aren’t eligible for the IID option. First offense OUI cases in Portland are heard at Cumberland County District Court.
Coordinated Defense on Both Tracks
We handle both the BMV administrative hearing and the criminal defense simultaneously.
Consequences Beyond the Courtroom
A first offense OUI conviction creates a permanent criminal record that employers, landlords, and professional licensing boards can access through background checks. Depending on your field, a conviction can affect professional licenses, security clearances, and job applications in ways that last long after the case closes.
For Maine residents, the Canada border is a practical concern. Entry may be denied following an OUI conviction, which affects anyone who lives, works, or travels near the border regularly. Auto insurance premiums typically increase significantly after a conviction, and some insurers may cancel coverage.
OUI Defense Strategies in Portland Cases
A first offense OUI charge doesn’t automatically become a conviction. There are multiple points in any case where the evidence may be challenged, and the outcome often turns on how thoroughly the defense examines every step of the stop, the investigation, and the testing process.
Common defense issues we examine in first offense OUI cases include:
Lawfulness of the traffic stop: Police must have reasonable suspicion before initiating a stop. Evidence gathered during an unlawful stop may be suppressible.
Field sobriety test administration: The Walk and Turn, Horizontal Gaze Nystagmus, and One Leg Stand tests are subject to challenge based on how the officer administered them, environmental conditions, and the driver’s physical or medical history.
Breathalyzer calibration and maintenance: Maine law requires certified operators, approved equipment, and strict protocols, including a 20-minute observation period before testing. Failure to follow those protocols can invalidate the result.
Rising BAC defense: A BAC reading at or above .08 at the time of testing may be challenged if evidence shows blood alcohol levels were still rising at the time of operation.
Medical conditions and medications: Certain conditions and prescription medications can produce elevated BAC readings or physical signs that resemble impairment. Those distinctions are litigable.
Implied consent advisement: If officers failed to correctly advise you of the consequences of refusing a chemical test under Maine’s implied consent law, any resulting refusal suspension and associated penalties may be contestable.
We invest significant time examining digital evidence and forensic reports in OUI cases. Tim Zerillo has chaired the NACDL’s Defending Modern Drug Cases seminar through its 18th annual session, which means our approach to cases involving drugs and prescription medications draws on national-level depth in forensic and pharmacological defense issues.

What to Expect in a Portland OUI Case: Arraignment Through Trial
The process in a Cumberland County OUI case follows predictable phases. Understanding each one helps you make better decisions along the way and keeps you prepared rather than reactive.
Arraignment
Arraignment is typically the first court appearance, where the OUI charge is formally presented and you enter a plea. Pleading not guilty preserves every option and allows defense preparation to begin in full. It’s not an admission that the case will go to trial. It’s the standard starting point for any contested matter.
Discovery & Case Review
After arraignment, we obtain the prosecution’s discovery package, which includes the police report, any video from cruiser or body cameras, breath test records, and officer training and certification documents. We examine each piece for inconsistencies, protocol failures, and constitutional issues before the next court date.
Dispositional Conference
A dispositional conference brings the defense attorney and prosecutor together to discuss whether the case can be resolved by agreement or must proceed to trial. In Maine, one possible resolution for a first offense OUI charge is a reduction to driving to endanger, a Class E misdemeanor that carries significantly lighter consequences than an OUI conviction. We explore every avenue before advising on how to proceed.
Motion Hearings
If the evidence supports it, we file motions to suppress evidence obtained through an unlawful traffic stop, an improperly administered breath test, a violation of implied consent advisement requirements, or other constitutional violations. Motion hearings give the court an opportunity to review whether the prosecution’s evidence was lawfully obtained. Suppressed evidence can materially weaken the case against you.
Trial
Most first offense OUI trials in Cumberland County District Court last one to two days. The prosecution must prove beyond a reasonable doubt that you were operating a vehicle while impaired or with a BAC of .08 or higher at or around the time of operation. We represent clients at every stage of this process, from the first appearance through trial and, when the circumstances warrant it, into appeals before Maine’s Law Court or the federal courts.
