While speeding in a school zone is still considered petty because it is fine only, the Illinois Secretary of State may suspend your license, depending on your driving history. The maximum fine is $1,000. The Illinois Legislature considers this type of charge more serious than other speeding tickets due to the public policy concern regarding the safety of children. As such, there is not court supervision for this offense which means it will count as points against your license if convicted.
The governing statute is 625 ILCS 5/11-605 which reads: “On a school day when school children are present and so close thereto that a potential hazard exists because of the close proximity of the motorized traffic, no person shall drive a motor vehicle at a speed in excess of 20 miles per hour while passing a school zone or while traveling on a roadway on public school property or upon any public thoroughfare where children pass going to and from school.”
For purposes of the statute, a school day runs from 7 am to 4 pm.
