Update 一下上此吃了罚单的出庭结果(I made a left turn in a designated lane, there was no sign says I cannot turn left from 7:00am-9:00am, there is a sign on the other side of the road says no right turn at that time frame. Police issued tickets to everybody one block later without asking)。我出庭辩护准备充分，那个警察却没来，所以 the case was dismissed。谢谢各位的解答，特别是柠檬椰子汁，多谢了。
其实我希望和那个警察对质，因为确实没有违规。我后来和一个邻居讲到此事，她猜在那个时间段，都是上班的人顺路右转进去开到底会是一中学 to drop off kids. 几乎没有人左转进来，我想想这是一个合理的解释 why there is no restrictions of turning left(everybody goes to work not coming back home), but restriction of turning right(drop off kids to school).
