I'm taking a road test next week. I want to be very clear on this!

The stop light turns yellow as you approach to turn right. You come to a full stop. You look around and see that it is safe to turn, but then the light turns red. Can you proceed before traffic starts moving, or do you have to sit and wait for traffic to go and turn when the way is clear? (the latter would cause a delay, so I don't know if I'll get a mark off for stop intersection -> starting -> speed [wait])...

Or even if the light turns red WHILE you make the turn, is that a traffic violation?

I'm curious to know if what I did was right. I was in a left-turn lane behind 3 cars waiting for the set of left-turn lights (the two lights with the "left turn signal" sign)... It was a much longer wait than usual, and the left turn lights did not turn green after perpendicular traffic had gone through. Instead, the left-turn signal for the traffic on the opposite side of the road turned green for oncoming traffic. For our side, it skipped the left turn signal. At this point, everybody in the left-turn lane was clearly frustrated. There was no oncoming traffic at all. After a minute...
