>Are there exemptions from this in the US? Yes, implied acceptance of risk. In short, if a person understood the chance of the bad thing happening when they chose to take part, they can't blame somebody else for it happening. (Unless the other person was negligent or intentionally caused harm.) As an example, if you join a pick-up soccer game at the park and lose a tooth while playing goalie, you're likely to lose any lawsuit against the guy who kicked the ball.
