License hearing: ask within 10 days

In writing within 10 days of the effective date of the suspension; a timely request stays the suspension. Count the days with the license-hearing window calculator.
Ignition interlock required in some cases

Higher BAC level. A first offender tested at 0.15 or more serves at least 48 hours in jail, which cannot be suspended.

Ignition interlock. A condition of early reinstatement (after 30 days of the 150-day suspension for a first offense).

A first OUI is a Class D crime with a mandatory $500 minimum fine and 150-day license suspension, and mandatory jail (48 hours) only if there is an aggravating condition such as a test of 0.15 or more; a second within 10 years carries at least 7 days of jail, a $700 fine and a 3-year suspension. The administrative-hearing request is due within 10 days of the effective date of the suspension.

How Maine compares

Of the 49 states with a confirmed BAC limit, 48 (Maine among them) use 0.08%; Utah has 0.05%.

On this site's reading of the statutes, of the 49 states with a confirmed rule, 21 require an ignition interlock after every first conviction, 18 in some cases and 8 leave it to the judge; 2 do not require one. Maine requires one in some cases.

The 40 states with a fixed deadline give from 6 to 90 days to ask for a license hearing (the middle one is 10); Maine gives 10.

03The process

How an OUI case moves through the system in Maine

The typical sequence, in general terms. Timing and details differ by county and by case.
  1. Arrest and booking

    Police arrest a driver on suspicion of OUI and take the person to the local jail, where booking records the arrest, the charge and the times.

  2. Release

    A person is released after posting bail, on their own recognizance, or after a hold. Amounts and timing differ by county.

  3. License action

    In writing within 10 days of the effective date of the suspension; a timely request stays the suspension.

  4. Arraignment

    The first court appearance, where the charge is read and a plea (guilty, not guilty or no contest) is entered.

  5. Pretrial resolution

    A case can end in a plea to a reduced charge, in a diversion or deferred program where the state has one, in a trial, or in a dismissal, depending on the state and the facts.

  6. Sentencing or trial

    For a first offense, Maine's statute provides jail of less than 1 year, a fine of $500 to $2,000, and a license suspension of 150 days. See the penalties table above.
