请各位大侠支招！

被警察开了一张右拐弯时，stop sign 没停的罚单， 真的是冤枉死了。不知怎么办好，请各位大侠支招。

仔细看了下罚单后面有一个What to do,列出了几项，

Pay the fine; Appear in court; Contest the Violation; Correct the violation; Request traffic school;Request trial by written declaration

想搞清楚 Contest the Violation;  Request trial by written declaration 到底是什么意思？Appear in court 和Contest the Vilation 有什么区别？

第二， 请大家给科普一下，在那么多的选项中，是选一项还是可以同时选多项？ 比如选Appear in court 和Request traffic school?

谢谢！
