Where Missouri ends and Illinois begins. it goes from 70 to 65. I had to look at my GPS when I got pulled over because I didn’t see any signs for anything to indicate a change in the state or speed limit. I might have been next to a truck or something, but no one else in the car saw any signs either. I got a ticket for going 72 in a 65. Four other people were pulled over in the same stretch within only a few miles.
