事故发生在哪个州，那个州的法律适用

假设你孩子和朋友从纽约开车到佛罗里大，中途在佛基尼亚出事故，官司可以在VA打。那么他就惨了，因为VA一般不承认事故前签订的liability waiver.

"The Virginia Supreme Court has not prohibited an injured person from suing the provider of a program, activity or event, if the injuries were caused by the providers’ negligence. - See more at: http://www.allenandallen.com/blog/are-liability-waivers-enforceable-in-virginia.html#sthash.9gQyghzy.dpuf"

所以你尽可以让你孩子给人家签，最后管不管用，要看事故发生地的本地法律和事故本身的细节。
