That mostly makes sense, but how would you sign a location where U-turns are allowed but the left turn would be a one-way violation and must therefore be prohibited?
Anyway, I’ve noticed inconsistencies in signage all over the place. I’ve realized that all the turn prohibitions should be grouped right next to the traffic light head, and both traffic light heads should have the exact same signs grouped next to them. Since it’s not my actual job I haven’t thought through how it should work when there is a separate left turn signal. I will however watch to see just what the inconsistencies are; if they are only the presence/absence of “bonus” signs then it’s not as bad as I thought.
