Not arguing about what the actual traffic laws are. I am arguing that this is objectively confusing design. "Left turn yield on green (CIRCLE)" does not mean that left turn yields on green. It means, "when turning left, but the solid light is green, and the left turn arrow is not lit up, yield to oncoming traffic. But if the solid light is green and the left turn arrow is lit, then do not yield." So you literally do not yield on green.
Sure you can just tell people to "please learn the road signs" no matter how terrible... or we can acknowledge that this is an asinine design. I have no idea why anyone would spend energy defending this.
