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.

Regulations promulgated by the Department specifying standards for safety glazing material on windshields shall, as a minimum, conform with those applicable Federal Motor Vehicles Safety Standards (49 CFR 571.205). These provisions apply to all motor vehicles of the first and second division but with respect to trucks, including truck tractors, the requirements as to safety glazing material apply to all glazing material used in doors, windows and windshields in the drivers' compartments of such vehicles.
    (c) It is unlawful for the owner or any other person knowingly to install or cause to be installed in any motor vehicle any glazing material other than safety glazing material conforming to the specifications prescribed by the Department.

        Such certification must be carried in the motor
    
vehicle at all times. The certification shall be legible and shall contain the date of issuance, the name, address, and signature of the attending physician, and the name, address, and medical condition of the person requiring exemption.
