Hi!
You can download faster speed limit here:

You get 110-120 MPH max for trucks in highways and fast motorways. However, the speed limit signs may display wrong indicator numbers since they're hard-coded in the map. That's why I made those signs covered with "X" symbol decal. You replace this mod with my other workshop mod, or add it in the Mod Manager and put it in the higher priority.
