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 5/16-102) (from Ch. 95 1/2, par. 16-102)
    Sec. 16-102. Arrests - Investigations - Prosecutions.
    (a) The Illinois State Police shall patrol the public highways and make arrests for violation of the provisions of this Act.
    (b) The Secretary of State, through the investigators provided for in this Act shall investigate and report violations of the provisions of this Act in relation to the equipment and operation of vehicles as provided for in Section 2-115 and for such purposes these investigators have and may exercise throughout the State all of the powers of police officers.
    (c) The State's Attorney of the county in which the violation occurs shall prosecute all violations except when the violation occurs within the corporate limits of a municipality, the municipal attorney may prosecute if written permission to do so is obtained from the State's Attorney.
    (d) The State's Attorney of the county in which the violation occurs may not grant to the municipal attorney permission to prosecute if the offense charged is a felony under Section 11-501 of this Code. The municipality may, however, charge an offender with a municipal misdemeanor offense if the State's Attorney rejects or denies felony charges for the conduct that comprises the charge.
