An ultrahazardous activity in the common law
of torts is one that is so inherently dangerous that a person engaged in such an activity can be held strictly liable for injuries caused to another person, even if the person engaged in the activity took every reasonable precaution to prevent others from being injured. In the Restatement of the Law
2d, Torts 2d, the term has been abandoned in favor of the phrase "inherently dangerous activity."
A person who is injured by one of these ultrahazardous activities while trespassing on the property
of the person engaged in the activity is barred from suing under a strict liability theory. Instead, they must prove that the property owner was negligent.
