Conn. Agencies Regs. § 14-253a-27
The commissioner may suspend or revoke any removable windshield placard, temporary removable windshield placard or special license plates, issued pursuant to sections 14-253a of the Connecticut General Statutes when the commissioner has reasonable belief that the person or organization to whom such removable windshield placard, temporary removable windshield placard or special license plates have been issued has used or permitted their use in a manner which violates the provisions of section 14-253a of the Connecticut General Statutes or the regulations adopted thereunder. Such person or organization, prior to the effective date of any such suspension or revocation shall be afforded notice and an opportunity for a hearing in accordance with Chapter 54 of the Connecticut General Statutes. Upon failure to request a hearing, or upon issuance of an interim order or a final decision by a hearing officer which affirms the commissioner's order to suspend or revoke, any special license plates, removable windshield placard or temporary removable windshield placard issued to or on behalf of such person or organization shall be returned to the commissioner.
