Legislature Passes “Speed Parity” for Cars and Trucks

The Illinois House and Senate have approved bills raising the speed limit for trucks on rural interstate highways to 65 miles per hour.

Neither bill affects the speed limit for trucks in Cook County. The House version also exempts the five counties that surround Chicago. Once the two chambers apporve identical bills, the measure will be sent to Gov. Pat Quinn for his signature.

The speed limit for cars on interstate highways is 65, but for semis the speed limit is 55. Traffic safety experts believe having two different limits increases the chances of accidents on the roads.

However, Democratic Sen. Don Harmon of Oak Park isn't convinced. When Missouri went to a uniform speed, Harmon said, fatalities jumped by more than 70.
