Illinois Compiled Statutes

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.

    (a) As used in this Section:
        (1) "Park district" means the following entities:
            (A) any park district organized under the Park
        
District Code;
            (B) any park district organized under the Chicago
        
Park District Act; and
            (C) any municipality, county, forest district,
        
school district, township, or other unit of local government that operates a public recreation department or public recreation facilities that has recreation facilities that are not on land owned by any park district listed in subparagraphs (A) and (B) of this subdivision (a)(1).
        (2) "Park zone" means the recreation facilities and
    
areas on any land owned or operated by a park district that are used for recreational purposes, including but not limited to: parks; playgrounds; swimming pools; hiking trails; bicycle paths; picnic areas; roads and streets; and parking lots.
        (3) "Park zone street" means that portion of any
    
street or intersection under the control of a local unit of government, adjacent to a park zone, where the local unit of government has, by ordinance or resolution, designated and approved the street or intersection as a park zone street. If, before the effective date of this amendatory Act of the 94th General Assembly, a street already had a posted speed limit lower than 20 miles per hour, then the lower limit may be used for that park zone street.
        (4) "Safety purposes" means the costs associated
    
with: park zone safety education; the purchase, installation, and maintenance of signs, roadway painting, and caution lights mounted on park zone signs; and any other expense associated with park zones and park zone streets.
    (b) On any day when children are present and within 50 feet of motorized traffic, a person may not drive a motor vehicle at a speed in excess of 20 miles per hour or any lower posted speed while traveling on a park zone street that has been designated for the posted reduced speed.
    (c) On any day when children are present and within 50 feet of motorized traffic, any driver traveling on a park zone street who fails to come to a complete stop at a stop sign or red light, including a driver who fails to come to a complete stop at a red light before turning right onto a park zone street, is in violation of this Section.
    (d) This Section does not apply unless appropriate signs are posted upon park zone streets maintained by the Department or by the unit of local government in which the park zone is located. With regard to the special speed limit on park zone streets, the signs must give proper due warning that a park zone is being approached and must indicate the maximum speed limit on the park zone street.
    (e) A first violation of this Section is a petty offense with a minimum fine of $250. A second or subsequent violation of this Section is a petty offense with a minimum fine of $500.
    (f) (Blank).
    (g) The Department shall, within 6 months of the effective date of this amendatory Act of the 94th General Assembly, design a set of standardized traffic signs for park zones and park zone streets, including but not limited to: "park zone", "park zone speed limit", and "warning: approaching a park zone". The design of these signs shall be made available to all units of local government or manufacturers at no charge, except for reproduction and postage.

    Sec. 11-606. Minimum speed regulation. (a) No person shall drive a motor vehicle at such a slow speed as to impede or block the normal and reasonable movement of traffic except when reduced speed is necessary for safe operation of his vehicle or in compliance with law.
    (b) Whenever the Department, The Illinois State Toll Highway Authority, or a local authority described in Section 11-604 of this Chapter determines, upon the basis of an engineering and traffic investigation concerning a highway or street under its jurisdiction that slow vehicle speeds along any part or zone of such highway or street consistently impede the normal and reasonable movement of traffic, the Department, the Toll Highway Authority, or local authority (as appropriate) may determine and declare by proper regulation or ordinance a minimum speed limit below which no person shall drive except when necessary for safe operation of his vehicle or in compliance with law. A limit so determined and declared becomes effective when appropriate signs giving notice of the limit are erected along such part or zone of the highway or street.

(a) No person shall drive a vehicle over any bridge or other elevated structure constituting a part of a highway at a speed which is greater than the maximum speed which can be maintained with safety to such bridge or structure, when such structure is sign posted as provided in this Section.
    (b) The Department upon request from any local authority shall, or upon its own initiative may, conduct an investigation of any bridge or other elevated structure constituting a part of a highway, and if it shall thereupon find that such structure cannot with safety to itself withstand vehicles traveling at the speed otherwise permissible under this Chapter, the Department shall determine and declare the maximum speed of vehicles which such structure can safely withstand, and shall cause or permit suitable signs stating such maximum speed to be erected and maintained before each end of such structure.
    (c) Upon the trial of any person charged with a violation of this Section proof of the determination of the maximum speed by the Department and the existence of such signs is conclusive evidence of the maximum speed which can be maintained with safety to such bridge or structure.

625 ILCS 5/11-612

    (625 ILCS 5/11-612)
    Sec. 11-612. Certain systems to record vehicle speeds prohibited. Except as authorized in the Automated Traffic Control Systems in Highway Construction or Maintenance Zones Act and Section 11-208.8 of this Code, no photographic, video, or other imaging system may be used in this State to record vehicle speeds for the purpose of enforcing any law or ordinance regarding a maximum or minimum speed limit unless a law enforcement officer is present at the scene and witnesses the event. No State or local governmental entity, including a home rule county or municipality, may use such a system in a way that is prohibited by this Section. The regulation of the use of such systems is an exclusive power and function of the State. This Section is a denial and limitation of home rule powers and functions under subsection (h) of Section 6 of Article VII of the Illinois Constitution.
