Me. Rev. Stat. tit. 4, § 164-A

The clerk of each division may accept a guilty plea to a criminal traffic offense upon payment of a fine and surcharge in accordance with a schedule of offenses and fines established by the Chief Judge. A person tendering payment of a fine without filing a signed waiver is deemed to have read and waived that person's rights, to understand that tendering payment is deemed a waiver and has the same effect as a judgment of the court and to understand that the record of the judgment will be sent to the Secretary of State.
