I also wonder how traffic routing works with right on red; since you cannot prohibit right turns under any circumstances, how do you direct traffic on T-junctions and 4-way junctions?
Went straight through in the sense of not stopping at all? Running a light is still illegal. (Also pedestrians have right of way if cars have a red light, so that sounds illegal regardless)

The traffic with the green light has right of way; everyone else is only allowed to turn if there's an opening. Does that answer the question, or did I misunderstand?
Traffic making a right on red must yield to all other traffic (driving straight from your left, and making a left turn from the opposite side) and pedestrians (in front of you and to the right). I think there is a law that U-turns yield to right turns on red though? Not sure about that.
Cases where it's prohibited are plentiful, usually in cases where a right on red can't be executed safely (like if there's poor visibility around a corner) or if right on red would be disruptive to traffic flow.
