Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

    (c) Trackless trolley coaches, as defined by Section 1-206 of this Code, and replica trolleys, as defined by Section 1-171.04 of this Code, may be equipped with a bell or bells in lieu of a horn, and may, in addition to the requirements of subsection (a) of this Section, use a bell or bells for the purpose of indicating arrival or departure at designated stops during the hours of scheduled operation.
