Actually, to lazy to dig it up, but TX has these huge lane sized shoulders on many roads. They are called "improved shoulders" and there are a half dozen cases where they are legally used as lanes. Including the case of a single lane road where someone is stopped in the main travel lane turning left, the shoulder may be used to pass them! (On the right). The more common (legal) use though is as a turning lane.
