Illinois Increases Speed Limit For Illinois Semi Trucks

Illinois Governor Pat Quinn recently signed a new law that will increase the speed limit for trucks from 55 mph to 65 mph on four (4) lane highways throughout most of the state. There is an important caveat for the bill, which keeps the speed limit at 55 mph in all the counties in the surrounding Chicagoland area. These counties include Cook, DuPage, Will, Lake, Kane and McHenry.  Other legislation dealing with truck weight and size standards also was signed Wednesday in Quincy by Quinn.  The new law goes into effect on January 1, 2012 and vehicle weighing scales will be used on the road by officers.

For starters, weighing trucks ensures that they do not damage or destroy roads. After all, roads and bridges can only handle so much weight. If a truck is over the regulated weight limit, it could cause irreparable damage to the highway.Current truck size and weight standards are a blend of Federal and State regulations and laws. Federal law controls maximum gross vehicle weights and axle loads on the Interstate System. Federal limits are 80,000 pounds gross vehicle weight, 20,000 pounds on a single axle, and 34,000 pounds on a tandem axle group.

I am not sure wether this is necessary legislation. I think it will be important to track the rates of highway trucking accidents at the new speed compared to previous years. I assume the legislation was passed to help clear traffic congestion on highways, and presumably, to make highways safer. I cannot say one way or the other right now if this increases safety.  I will be looking for articles from highway safety experts to weigh in on this issue.
