I am California. I was making a stop in a four-way-stop when I saw a pedestrian crossing right in front of my vehicle from right to left. When he was at the far side, about one feet of the curb ramp, I advanced, making a left. As soon as I entered the intersection I noticed he was in the crosswalk of the lane into which my vehicle was turning. I reduced my speed, and stopped my vehicle. I waited for the pedestrian to cross, and when he was crossing right in front of my car, two more pedestrian entered the same crosswalk as well. I remained stopped waiting for the pedestrians to finish crossing the street. Then another pedestrian entered into the same crosswalk. Once again, I remained stopped and waited until the last pedestrian finished crossing the street. Then, I advanced and as soon as my car moved, a cop pull me over. All of the pedestrian walked at normal pace, without jumping back, stopping or even reacted defense. The cop said he pulled me over because I didn't yield. I said that I did yield and he said that I didn't yield to the first pedestrian. What are my chances of winning this ticket if I fight? Should I ask for a trial by written declaration or should I just go to court? My English is not very good and I don't know if I would be able to explain in writing the situation in a correct way. By the way, everything happened very closed to a high school and I think pedestrian were high school students.
