In the U.S. and Canada, pentagon-shaped signs are used in place of the usual diamond-shaped signs.

At such intersections, the exclusive turn signals indicate that there are no permissive turn movements at that intersection, and that only exclusive turn movements are allowed. At those intersections, the signals with circular lenses govern movements in all directions ""except"" those in the direction which the turn signal controls. This means that if"
