If you are under 21 years of age, Maine has a special law for you. If you are found operating, or attempting to operate, a motor vehicle with any measurable amount of alcohol in your body, you will lose your license for one year. If you refuse a test, you will lose your license for at least 18 months. If you have a passenger under 21 years of age, an additional 180 day suspension will be imposed.
Drivers under 21 with a BAC of .08% or more can be prosecuted for the criminal offense of OUI, but the license suspension must be for one year.
