Ill. Admin. Code tit. 92 § 2520.705
The Authority, or its duly authorized agent, shall give a Notice of Violation to the respondent of the alleged toll violation. The Notice of Violation shall be served on the respondent by First Class United States Mail or other means as provided by law, postage prepaid, to the address of the registered owner of the cited vehicle as recorded with the Secretary of State's vehicle registration records or to the lessee of the cited vehicle at the last address known to the lessor of the cited vehicle at the time of the lease. The Notice of Violation shall specify the date, approximate time and location of the violations cited, the regulation violated, the State registration number of the cited vehicle (if available), the amount of the unpaid tolls, and the applicable fines and fees. The Notice of Violation shall include a statement that failure to satisfy any fine or fee imposed by the Authority may result in the Secretary of State suspending the driving privileges, vehicle registration, or both, of the person failing to satisfy the fines or fees imposed by the Authority for non-payment of tolls. The Notice of Violation shall inform the respondent of the availability of a hearing in which the violation may be contested on its merits and the manner in which the hearing may be conducted. The Notice of Violation shall inform the respondent that failure to contest the alleged violations in the manner and time provided shall be deemed an admission of liability and that a final order of liability may be entered on that admission. The Notice of Violation shall further state that failure to either pay the indicated toll, fine or fee or to request a hearing on the merits will result in a final order of liability in the amount of the toll, fine or fee indicated. A duly authorized agent of the Authority may perform or execute the preparation, certification, affirmation, or mailing of the Notice of Violation.
