The General Assembly finds that electronic toll collection systems in Illinois should be standardized to promote safety, efficiency, and traveler convenience. The Department shall cooperate with the Illinois State Toll Highway Authority and with other public and private entities to further the goal of standardized toll collection in Illinois. If electronic toll collection is used on any highway constructed or maintained by the Department or by a private entity pursuant to an agreement with the Department, the Department shall require the electronic toll collection system to be compatible with the electronic toll collection system used by the Illinois State Toll Highway Authority. The Department may enter into an intergovernmental agreement with the Illinois State Toll Highway Authority to provide for such compatibility or to have the Authority provide electronic toll collection or toll violation enforcement services.
