"The Governor is fond of saying 'Let the will of the people be the law of the land,' yet he was quick to veto legislation that was sponsored by 36 Senators representing Chicago, suburban and downstate areas of Illinois," Oberweis said. "And today, a majority of my colleagues in the Senate joined me in overriding the Governor's veto."

Quinn vetoed Oberweis' Senate Bill 2015 on Aug. 26, citing evidence that tollway drivers already exceed the speed limit in many cases, which he said can lead to serious accidents. Oberweis noted a recent study showed that differential speeds between vehicles were actually more problematic. The original 70 mph speed limit law he sponsored last year – Senate Bill 2356 – already provides tougher penalties for people who exceed the speed limit by more than 26 mph.

"The Governor's argument that tollway drivers already exceed the speed limit is a great argument as to why we should increase the current speed limit to 70 mph," Oberweis said. "And it is an argument we have already addressed in the original law. Those who exceed the 70 mph limit by more than 26 mph now face tougher penalties."

Oberweis said the original law, which took effect Jan. 1, provides public safety enhancements in the form of a lowered threshold upon which the penalty for speeding is increased from a petty offense to a misdemeanor. Speeding in excess of 26 mph but less than 35 mph (currently 31-40 mph) will be a Class B misdemeanor. Speeding in excess of 35 mph (currently 40 mph) will be a Class A misdemeanor.
