dude.. you asian?
you're never allowed to u-turn at a set of lights.. that's just stupid, it's a traffic accident waiting to happen!
you either go forward, left, or right.. you dont chuck a u-turn!!!
you do realise that other cars are allowed to move the same time as you right? so if you were chucking a u-ie, and some car on the RHS also wanted to go along the same road.. what'll happen???
i dont think you should even bother to appeal because the police is right
it's just common sense it's against the law the u-turn at a light =.= you go whichever direction the light signals you to.. i've never seen a light that bends backwards
