Speeding tickets for up to 30 miles per hour over the legal speed limit are considered petty offenses. Petty means it is a fine only offense. Speeding tickets are the most common violation of the vehicle code in Illinois but should not be taken lightly. Speeding 31 mph over the speed limit can be charged as a class A misdemeanor.
The governing statute for speeding, 625 ILCS (Illinois Compiled Statutes) 5/11‑601(a) provides: “No vehicle may be driven upon any highway of this State at a speed which is greater than is reasonable and proper with regard to traffic conditions and the use of the highway, or endangers the safety of any person or property. The fact that the speed of a vehicle does not exceed the applicable maximum speed limit does not relieve the driver from the duty to decrease speed when approaching and crossing an intersection, approaching and going around a curve, when approaching a hill crest, when traveling upon any narrow or winding roadway, or when special hazard exists with respect to pedestrians or other traffic or by reason of weather or highway conditions. Speed must be decreased as may be necessary to avoid colliding with any person or vehicle on or entering the highway in compliance with legal requirements and the duty of all persons to use due care.”
