A defendant moving for summary judgment in a negligence action has the burden of establishing, prima facie, that he was not at fault in the happening of the accident. There can be more than one proximate cause of an accident, and it is for the trier of fact to determine the issue of proximate cause. However, proximate cause may determined as a matter of law where the defendant's negligence merely created the opportunity for, but did not cause, the event that resulted in harm to the plaintiff.
