Maine divides first-offense OUI into two tiers. At BAC .15 or higher, you enter the aggravated tier—longer mandatory suspension, longer IID requirement, and a different court petition path for restricted driving.
What Maine Defines as Aggravated OUI and Why the .15 BAC Line Matters
Maine Revised Statutes Title 29-A § 2411 defines aggravated OUI as operating a vehicle with a blood alcohol content of .15 or higher. This is double the legal limit of .08. The distinction is not academic—aggravated classification changes your mandatory minimum suspension period, the length of ignition interlock device requirement, and the court's discretion in granting restricted driving privileges.
A first-offense OUI below .15 carries a 150-day license suspension. A first-offense aggravated OUI at .15 or above carries a minimum 18-month suspension. The Bureau of Motor Vehicles applies this suspension administratively within days of your arrest, independent of any criminal court proceeding. Even if your criminal case is still pending, the administrative suspension is in effect.
The court petition for a restricted license becomes available after a mandatory 30-day hard suspension period for both tiers, but aggravated cases face stricter scrutiny. Judges expect documented proof of hardship, verified employment or essential medical need, and confirmation that you have already installed an ignition interlock device before the hearing. Standard first-offense cases may receive restricted privileges without IID during the petition window; aggravated cases do not.
How the Aggravated OUI Suspension Timeline Works in Maine
Maine's aggravated OUI suspension runs in two phases: the administrative BMV suspension triggered by your arrest, and the court-imposed suspension triggered by conviction. Both apply to the same license, but they do not stack—the court suspension typically runs concurrent with the BMV suspension once conviction occurs.
The BMV issues an administrative license suspension within 30 days of your arrest if you submitted to a chemical test showing .15 BAC or higher. This suspension begins immediately upon notice. You have 10 days from the date of the suspension notice to request a BMV administrative hearing to contest the suspension. If you do not request a hearing, or if the hearing officer upholds the suspension, the 18-month period begins.
After 30 days of hard suspension—no driving whatsoever—you become eligible to petition the court for a restricted license under 29-A M.R.S. § 2412-A. The petition requires proof of enrollment in Maine's Driver Education and Evaluation Program (DEEP), proof of SR-22 insurance filing, and proof that an approved ignition interlock device has been installed on any vehicle you will operate. The court does not grant restricted privileges for aggravated cases without confirmed IID installation. Bring the IID installation certificate to your hearing.
If the court grants the restricted license, you are authorized to drive only for court-approved purposes: work, school, medical appointments, DEEP program attendance, and other essential travel the judge deems necessary. The restricted license remains valid for the duration of your suspension period, provided you maintain continuous SR-22 coverage, keep the IID installed and functioning, and do not violate the terms of the restriction.

Ignition Interlock Device Requirements for Aggravated OUI Cases
Maine law requires installation of an ignition interlock device for the full duration of any restricted license granted in an aggravated OUI case. This is not optional. The device must be installed before the court hearing—judges will not grant restricted driving privileges on the promise that you will install it later.
An approved IID vendor in Maine installs the device on your vehicle. The Maine BMV maintains a list of approved vendors. Installation costs typically range from $100 to $150, and monthly monitoring and calibration fees run $70 to $90. You are responsible for all costs. The device requires you to provide a breath sample before the engine will start. If your BAC registers above the programmed threshold (usually .02 or .025), the vehicle will not start.
The IID logs every start attempt, every failed test, and every instance of tampering or circumvention. The vendor downloads this data monthly and reports violations to the court and the BMV. If you attempt to bypass the device, drive a non-equipped vehicle during your restricted period, or accumulate multiple failed breath tests, the court can revoke your restricted license and you return to full suspension with no driving privileges.
For aggravated first-offense cases, the IID requirement lasts the full 18 months if you are granted a restricted license. For second or subsequent OUI offenses, the IID requirement extends beyond the suspension period into post-reinstatement driving—often three to six years total. Verify the exact duration with the court at your restricted license hearing.
How to Petition for a Restricted License After Aggravated OUI
Maine's restricted license process for aggravated OUI is court-driven, not a BMV administrative application. You petition the court that handled your OUI case, or if no criminal case has been filed, the District Court in the county where you reside.
The petition must be filed after the mandatory 30-day hard suspension period has elapsed. Filing earlier results in automatic denial. The petition package must include proof of enrollment in DEEP (the state-mandated alcohol education and evaluation program), proof of SR-22 insurance filing with the Maine BMV, proof of IID installation by an approved vendor, a sworn statement describing the hardship you face without driving privileges, and documentation supporting your claim—employer letters, medical appointment records, school enrollment verification.
The court schedules a hearing. You or your attorney present evidence of hardship. The judge evaluates whether your need for restricted driving is genuine and whether granting the privilege poses an unacceptable risk to public safety. Aggravated cases face higher scrutiny than standard OUI cases. Judges deny petitions when the stated hardship is weak, when documentation is missing, when IID is not yet installed, or when the petitioner has prior OUI convictions or other driving violations on record.
If the petition is granted, the court issues an order specifying approved driving purposes, approved hours, and the requirement to maintain IID and SR-22 for the duration. You take the court order to the BMV to obtain the physical restricted license document. The BMV charges a processing fee (typically $50, though aggravated cases may incur additional fees). The restricted license lists the conditions imposed by the court. Driving outside those conditions is a criminal offense under Maine law—operating after suspension or in violation of license restriction, punishable by additional fines, jail time, and extended suspension.
SR-22 Filing Requirements and Premium Impact for Aggravated OUI
Maine requires SR-22 insurance filing for all OUI-related suspensions, including aggravated cases. SR-22 is not a type of insurance—it is a certificate your insurance carrier files with the Maine BMV confirming that you carry at least the state minimum liability coverage: $50,000 per person for bodily injury, $100,000 per accident for bodily injury, and $25,000 for property damage.
You must obtain SR-22 before petitioning for a restricted license. The filing fee ranges from $15 to $50 depending on the carrier. The SR-22 filing itself is cheap—the premium increase is not. Carriers classify aggravated OUI as a high-risk event. Expect premiums to increase by 80% to 150% over your pre-conviction rate. Monthly premiums for drivers with aggravated OUI in Maine typically range from $180 to $320 per month, compared to $85 to $140 for clean-record drivers.
The SR-22 filing requirement lasts three years from the date of conviction, not from the date of suspension or the date you obtain the restricted license. If your carrier cancels your policy or you allow coverage to lapse at any point during the three-year period, the carrier notifies the BMV immediately and your license is suspended again. The three-year clock does not pause—it restarts from zero if you lapse.
If you do not own a vehicle, you still need SR-22 to obtain a restricted license in Maine. Non-owner SR-22 policies provide liability coverage when you drive a vehicle you do not own. Premiums for non-owner SR-22 policies typically run $40 to $80 per month. Carriers writing non-owner SR-22 in Maine include Geico, Progressive, Dairyland, The General, and Bristol West. Not all carriers offer non-owner policies—call before assuming coverage is available.
What Happens If You Violate Restricted License Terms
Violating the terms of your restricted license in Maine triggers immediate suspension and criminal charges. The most common violations: driving outside approved hours, driving for non-approved purposes, driving a vehicle without an installed IID, failing monthly IID calibration, accumulating failed breath tests, or allowing SR-22 coverage to lapse.
If law enforcement stops you and you are driving outside the restrictions listed on your court order, you are charged with operating after suspension (OAS). OAS is a Class D misdemeanor in Maine, punishable by up to 364 days in jail and fines up to $2,000. Your restricted license is revoked on the spot, and you return to full suspension with no driving privileges. You must serve the remainder of your original suspension period before becoming eligible to apply for full reinstatement.
IID violations reported by the vendor—missed calibrations, failed breath tests, evidence of tampering—are forwarded to the court and the BMV. The court can revoke your restricted license based on vendor reports alone, without a separate criminal charge. You receive a notice of revocation, and your restricted privilege ends immediately. Some judges require a second hardship hearing to restore restricted privileges after an IID violation; others deny restoration outright.
SR-22 lapse is automatic suspension. The carrier notifies the BMV electronically when your policy cancels or lapses. The BMV suspends your restricted license the same day. To reinstate, you must obtain new SR-22 coverage, pay a reinstatement fee (currently $50 for administrative suspension, higher for OUI-related lapse), and in some cases re-petition the court for restricted privileges depending on how long the lapse lasted.
Full License Reinstatement After Aggravated OUI Suspension
Full reinstatement after an aggravated OUI suspension in Maine requires completion of the full 18-month suspension period, completion of the DEEP program, payment of a reinstatement fee, proof of continuous SR-22 filing, and in some cases retesting. The reinstatement fee for OUI-related suspensions in Maine is typically $100 or more, higher than the standard $50 base fee for non-OUI administrative suspensions.
You must complete DEEP before the BMV will process your reinstatement application. DEEP includes an initial assessment, an education component (usually a multi-week course), and in some cases a treatment requirement if the assessor determines you meet clinical criteria for substance use disorder. Failure to complete DEEP extends your suspension indefinitely—the clock does not run until the program is complete.
Once DEEP is complete, you submit proof of completion to the BMV along with your reinstatement application, proof of continuous SR-22 coverage for the required three-year period, and payment of the reinstatement fee. The BMV reviews your driving record. If you accumulated additional violations during the suspension period—driving on a suspended license, further OUI arrests, refusal to submit to testing—the BMV may impose additional suspension time or deny reinstatement.
After reinstatement, the SR-22 filing requirement continues for the remainder of the three-year period. If your conviction occurred 18 months ago and you are just now reinstating, you still owe 18 months of SR-22 coverage post-reinstatement. The three-year clock begins at conviction, not at reinstatement. Budget for continued high-risk premiums throughout this period.
