Illinois Statutes Chapter 625. Vehicles § 5/3-405.2. Improper plates

§ 3-405.2. Improper plates. The Secretary of State shall refuse to issue any license plates bearing a combination of letters or numbers, or both, which creates a potential duplication or, in the opinion of the Secretary, (1) would substantially interfere with plate identification for law enforcement purposes, (2) is misleading, or (3) creates a connotation that is offensive to good taste and decency.

The Secretary may revoke any such plates issued previously. Any person who has his or her plates revoked under this Section may acquire at no charge new plates and any required stickers of the same category and for the same period of registration.
