Illinois to expand width limit

Illinois Gov. Pat Quinn has signed legislation that will raise the legal limit on vehicle width from 96 to 102 inches on Class III highways, nondesignated highways and local roads.

Prior to passage of the legislation, 102-inch-wide vehicles were restricted to Class I and Class II highways only. Effective Jan. 1, 2010, the new law creates a uniform 102-inch width limit on all roads in Illinois.
