Driving test

Why the traffic light had to change to red when i reached that intersection...just because i stopped over the pedestrian line on the road and they failed me...so unfair...basically i was about to turn right, it was green all the way, then it changed to yellow then red before i can cross over. Therefore i stopped, and stopped over the line, and i thought i have to stop, because it was yellow light...so i failed because of that kind of situation. Feeling so unfair...not that i cant drive, but is that bloody traffic lights...At least now i know that i can go at yellow light if i am not safe to stop...23rd September...gonna challenge Vic Road again...
