Speeding In Illinois Doesn't Save You Time, But It Does Waste MoneyI remember the first time I got a speeding ticket. GummyBone GummyBoneI would say that the majority of drivers in Illinois and Rockford go over the speed limit at least some of the time.

Actually, another thing learned was that going over the speed limit will cost you more money.
