At a traffic light controlled intersection, who has right of way between a U-turning vehicle and a right-turning vehicle? Consider the following cases, assuming no other applicable signage:
Case 1 - Right on red
Here, the person U-turning has a green light, while the person right-turning has a red light. I believe in this case, the U-turning person has right of way because the vehicle turning right should come to a full stop before proceeding, but am not sure.
Case 2 - Right green arrow
In this case the U-turning vehicle has advance green light, allowing left, right, and straight directions (don't know about U-turn). The right turning vehicle has a green right arrow.
I am most looking for answers for Ontario, Canada, but would accept answers for other jurisdictions with similar traffic laws (at least where they don't outright ban U-turns at intersections).
Note: The Ontario driver's handbook, and applicable laws don't seem to mention U-turns much. In particular, it's not explicit that U-turns are even allowed at intersections, but they seem to be according to this Reddit discussion, and according to the no U-turn signs present at some intersections.
