Concept
In nations where automobiles drive on the right side of a road, traffic traveling in a clockwise direction around a loop will always be in the "inner" lane(s) (assuming that there is no lane crossing). Likewise, traffic traveling in a counterclockwise direction will always be in the "outer" lane(s). "Inner" and "outer" labels stem from this reasoning, applying the concept of concentric loops to the geographic characteristics of circular road or rail.
