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.

625 ILCS 5/11-603

    (625 ILCS 5/11-603) (from Ch. 95 1/2, par. 11-603)
    Sec. 11-603. Alteration of limits by Toll Highway Authority. Whenever the Illinois State Toll Highway Authority determines, upon the basis of an engineering and traffic investigation concerning a toll highway under its jurisdiction, that a maximum speed limit prescribed in Section 11-601 of this Chapter is greater or less than is reasonable or safe with respect to conditions found to exist at any place or along any part or zone of such highway, the Authority shall determine and declare by regulation a reasonable and safe absolute maximum speed limit at such place or along such part or zone, and the speed limit shall conform with the maximum speed limit restrictions provided for in Section 11-601 of this Code. A limit so determined and declared becomes effective, and suspends the application of the limit prescribed in Section 11-601 of this Chapter, when (a) the Department concurs in writing with the Authority's regulation, and (b) appropriate signs giving notice of the limit are erected at such place or along such part or zone of the highway. Electronic speed-detecting devices shall not be used within 500 feet beyond any such sign in the direction of travel; if so used in violation hereof, evidence obtained thereby shall be inadmissible in any prosecution for speeding.
