也在准备N400，对于traffic ticket不是很确定，看了USCIS的常见问题 Link: [url=https://www.uscis.gov/sites/default/files/files/article/M-476.pdf]https://www.uscis.gov/sites/default/files/files/article/M-476.pdf[/url] “Note that unless a traffic incident was alcohol or drug related, you do not need to submit documentation for traffic fines and incidents that did not involve an actual arrest if the only penalty was a fine less than $500 and/or points on your driver’s license.” 我的理解是不需要提供documentation，不过至于是不是要需要填YES。在网上找了信息，觉得靠谱的是下面两个选择，1）填YES，然后带着文件和缴费记录，在面试的时候解释；2）填NO，面试的时候问起就说以前有过交通违章，已经交过罚款了。
