Talking about signals we have a weird one here in Winnipeg. Apparently its a special one that is designed to allow u-turns only. The signals manager was on the TV news a while ago saying its the only one that he knows of in Canada.
From looking at it I think that it is a special lens made up to go over a standard green led fixture. The lens looks like a
u-turn sign with a curved u and arrow pointing down small enough to fit on a signal head.
The intersection that it is on does not allow left turns (east) as its a one way street going west. Because of a shopping center 1/4 block down on the left side going north the traffic department had the idea of allowing traffic going south to make a signal protected u-turn to access it instead of putting in a median cut.
