Vieux routier = old truck driver

Somehow, I don't think it conveys the same sense of wizened experience that Old Hand does. I picture some old, chain-smoking dude, his checkered shirt missing the bottom button; riding in the cab of his old beat-up Mack truck with "Born to ride the white line" spray-painted on the doors and the booby-chick mud flaps, pulling on the bullhorn-line as he sees a young chickie by the side of the road.
