Assuming you were the lead car in the left-turn lane, I think the officer erred in citing you. The law can't require you to predict when other people are going to act illegally so you can plan accordingly. It also doesn't make sense that not even one car per cycle is allowed to turn left across such a traffic flow. You could have sat there for hours following that advice.
