about left turns and U-turns

[Bravoexo]

How about the rule of following traffic signs? No mention?

My take... that intersection is busy. I wouldn't want to watch out for U - turners there when it's green and I'm on macapagal going in the opposite direction. Left turn, ok kasi stop sigurado ako kasi signal light controlled yung left turn na yan. (in some instances in the US, signal light controlled din ang U turn nila or specific lane ang u turn , kasabay ng left signal light...)
