Can I file a lawsuit if I was hit by another driver while not wearing a helmet?

Yes. However, under Nevada’s comparative negligence rules, any compensation you may be entitled to for your injuries may be reduced if the insurance company or a jury determines that some of your injuries were caused in part by your failure to wear a helmet. If you’re found to be more than 50 percent responsible for causing the motorcycle accident, you could be barred from obtaining any compensation whatsoever.
