Illinois Truck Speed Limit Rises to 65 mph

Illinois’ law allowing truckers in most parts of the state a 65-mph speed limit took effect Sunday.

That’s up from the current 55-mph limit, and applies to all four-lane divided highways except for the six counties around Chicago, which retain the lower limit.

Trucks already were allowed to run up to 65 mph on rural highways in the state, under legislation approved in 2009.
