Any municipality may provide by ordinance for a program of vehicle immobilization and impoundment in cases in which the Department of Healthcare and Family Services has certified to the municipality under Section 10-17.13 of the Illinois Public Aid Code that the registered owner of a vehicle owes past due support. The program shall provide for immobilization of any eligible vehicle upon the public way by presence of a restraint in a manner to prevent operation of the vehicle and for subsequent towing and impoundment of such vehicle solely upon the certification of past due support by the Department of Healthcare and Family Services. Further process, hearings, or redetermination of the past due support by the municipality shall not be required under the ordinance. The ordinance shall provide that the municipality may terminate immobilization and impoundment of the vehicle if the registered owner has arranged for payment of past and current support obligations in a manner satisfactory to the Department of Healthcare and Family Services.
