Unless otherwise specified by law, the minimum fine for a conviction or supervision disposition on a minor traffic offense is $25 and the minimum fine for a conviction, supervision disposition, or violation based upon a plea of guilty or finding of guilt for any other offense is $75. If the court finds that the fine would impose an undue burden on the victim, the court may reduce or waive the fine. In this Section, "victim" shall not be construed to include the defendant. Except for traffic fines, fines and assessments, such as fees or administrative costs, authorized under this Section shall not be ordered or imposed on a minor subject to Article III, IV, or V of the Juvenile Court Act of 1987, or a minor under the age of 18 transferred to adult court or excluded from juvenile court jurisdiction under Article V of the Juvenile Court Act of 1987, or the minor's parent, guardian, or legal custodian.
