I sure as heck hope not. One of the things I love about this state is that the speed limit is somewhat reasonably set here. It still should be a lot higher inside the perimeter and in the near suburbs traffic permitting. The other is that the first points ticket is for 15 miles per hour plus over the speed limit.
Seems like they trust you here more than they do in other states to drive the speed that the road was designed for. This lower truck speed limit is bad news. I hope you're wrong.
