EXPRESS ASSUMPTION OF RISK
If, prior to an event in which the plaintiff was injured as a result of defendant’s negligence, the plaintiff had expressly assumed the risk of such injury by specifically agreeing with the defendant that he, the plaintiff, would not hold the defendant responsible if an injury should be caused by the defendant’s negligence, the plaintiff may not recover damages from the defendant for that injury.
