Common questions
Frequently Asked
4
Does assumption of the risk require that the plaintiff know the specific danger that ultimately causes harm?+
Yes. The doctrine applies only when the plaintiff voluntarily encounters a known risk. A plaintiff who lacks actual knowledge of the danger cannot be said to have assumed it.
Supporting sources
How does assumption of the risk differ from contributory negligence?+
Assumption of the risk focuses on the plaintiff's voluntary acceptance of a known hazard. Contributory negligence concerns unreasonable conduct that contributes to the injury, even without knowledge of the specific risk.
Supporting sources
Can a party assume the risk of a co-occupant's consent to a police search?+
Yes. A person who shares premises with another assumes the risk that the co-occupant may permit officers to search the common areas, rendering the consent valid against the non-consenting party.
Supporting sources
Does assumption of the risk bar recovery in reckless conduct cases?+
Yes. A plaintiff who assumes the risk arising from the defendant's reckless disregard of safety is barred from recovery for resulting harm under the Restatement rule.
