No one is supposed to cross the limit line at a stop light. However, when a motorcycle cuts in line while all traffic is stopped, don't worry so much. Passing to the front of the line, lane splitting, but not technically running the redlight is not illegal. He'll be gone as soon as the light goes green and you can't catch him. Not your problem anymore, is it. When I see that happen I don't care. What do you think, you're waiting to pay a checkstand?
