How much does a OUI cost in Maine?

A first OUI in Maine carries a statutory fine of $500–$2,000. This guide stacks every cost layer an official Maine source prices — the fine, court costs, the license reinstatement fee, the OUI program, ignition interlock, and the SR-22 insurance filing — and says plainly which layers no official source prices at all.

Maine OUI costs at a glance	Figure
Statutory fine — first OUI	For a first OUI offense with no prior offenses in 10 years, Maine law (29-A M.R.S. 2411) sets a fine of not less than $500, and not less than $600 if the person failed to submit to a chemical test. A first OUI is a Class D crime, for which Maine's general sentencing law (17-A M.R.S. 1704) sets a maximum fine of $2,000. A $30 surcharge is added to the fine for the Highway Fund to cover alcohol test administration and analysis ($125 if the person was under the influence of drugs or a combination of alcohol and drugs).
Statutory fine — second OUI	The statute separates a second offense: $700–$2,000. Second offenses also carry longer suspensions and program requirements — see the sections below.
Court costs & fees	No single statewide court-cost figure is published in the Maine OUI statute or on the Bureau of Motor Vehicles and DHHS pages reviewed. Court costs are handled in the individual case, separate from the fine and the testing surcharge.
License suspension — first offense	The court orders a license suspension of 150 days for a first OUI offense. If a passenger under 21 was in the vehicle, an additional 275-day suspension applies.
License reinstatement fee	The Maine Bureau of Motor Vehicles requires applicable fees to be paid before a license is reinstated, but no OUI reinstatement fee amount could be verified from an official page opened during this research (the BMV suspension page would not load), so no fee is listed here.
Ignition interlock	Conditional — restricted license / court order — Maine's ignition interlock program is voluntary and is used for early license restoration: a person with one OUI may have the license reinstated after serving 30 days of the 150-day suspension if an approved ignition interlock device is installed and maintained for the rest of the suspension term. The Bureau of Motor Vehicles charges a $50 application fee to apply for the ignition interlock program. No official install or monthly device costs are published.
OUI education / treatment program	Maine's legislatively mandated program for OUI offenders is DEEP, the Driver Education and Evaluation Programs, administered through the Department of Health and Human Services, which provides education, evaluation, and treatment or counseling services. The DHHS page reviewed publishes no in-state program fee, so no amount is listed.
SR-22 insurance filing	No SR-22 requirement after an OUI could be verified from the official Maine pages reviewed, so SR-22 status is recorded as unverified.

The fine

For a first OUI offense with no prior offenses in 10 years, Maine law (29-A M.R.S. 2411) sets a fine of not less than $500, and not less than $600 if the person failed to submit to a chemical test. A first OUI is a Class D crime, for which Maine's general sentencing law (17-A M.R.S. 1704) sets a maximum fine of $2,000. A $30 surcharge is added to the fine for the Highway Fund to cover alcohol test administration and analysis ($125 if the person was under the influence of drugs or a combination of alcohol and drugs).

Court costs & fees

No single statewide court-cost figure is published in the Maine OUI statute or on the Bureau of Motor Vehicles and DHHS pages reviewed. Court costs are handled in the individual case, separate from the fine and the testing surcharge.

License suspension & reinstatement

The court orders a license suspension of 150 days for a first OUI offense. If a passenger under 21 was in the vehicle, an additional 275-day suspension applies.

The Maine Bureau of Motor Vehicles requires applicable fees to be paid before a license is reinstated, but no OUI reinstatement fee amount could be verified from an official page opened during this research (the BMV suspension page would not load), so no fee is listed here.

The national picture — which states charge the most to reinstate — is in our license reinstatement guide.

Ignition interlock

Maine's ignition interlock program is voluntary and is used for early license restoration: a person with one OUI may have the license reinstated after serving 30 days of the 150-day suspension if an approved ignition interlock device is installed and maintained for the rest of the suspension term. The Bureau of Motor Vehicles charges a $50 application fee to apply for the ignition interlock program. No official install or monthly device costs are published.

How interlock pricing works (installation, monthly lease, calibration, removal) is in our ignition interlock cost guide.

OUI education & treatment program

Maine's legislatively mandated program for OUI offenders is DEEP, the Driver Education and Evaluation Programs, administered through the Department of Health and Human Services, which provides education, evaluation, and treatment or counseling services. The DHHS page reviewed publishes no in-state program fee, so no amount is listed.

SR-22 & insurance

No SR-22 requirement after an OUI could be verified from the official Maine pages reviewed, so SR-22 status is recorded as unverified.

Towing, impound & other charges

A $30 surcharge is added to a first-offense OUI fine for the Highway Fund ($125 where the offense involved drugs or a combination of alcohol and drugs), and applying for early restoration through the ignition interlock program carries a $50 application fee.

Worked total: the verified charges stacked

Item	Cost
Statutory fine	$500–$2,000
Total of the verified state-set charges above	$500–$2,000

That total is deliberately incomplete: it leaves out everything no official Maine source prices statewide — court costs where they are set county by county, interlock lease payments to a private vendor, towing and storage, and the insurance increase that follows an SR-22.
