8.2 Assumption of Risk

2 min readjuly 23, 2024

is a legal defense where someone voluntarily accepts a known danger. It involves three key elements: , , and accepting potential consequences. This concept plays a crucial role in determining liability in various situations.

There are two types of risk assumption: express and implied. Express involves explicit agreements, while implied is inferred from behavior. The defense's effectiveness varies across different contexts, like sports, employment, and consumer products, often balancing individual responsibility with safety obligations.

Assumption of Risk

Elements of assumption of risk

Top images from around the web for Elements of assumption of risk
  • Voluntary exposure to a known danger plaintiff must freely choose to encounter the risk without coercion or duress
  • Appreciation and understanding of the risk involved plaintiff must have actual knowledge of the specific risk and comprehend its nature and potential consequences (skydiving, bungee jumping)
  • Acceptance of the risk and its potential consequences plaintiff must voluntarily agree to bear the risk and any resulting harm (rock climbing, whitewater rafting)

Express vs implied risk assumption

  • plaintiff explicitly agrees to assume the risk through a written contract, waiver, or release ( for parasailing)
  • plaintiff's conduct or actions demonstrate a willingness to accept the risk without an explicit agreement
    • in an activity that cannot be eliminated without altering its fundamental nature (being tackled in football, falling off a horse while horseback riding)
    • risks created by the defendant's negligence, but the plaintiff knowingly proceeds despite the risk (using a defective ski lift, walking on a visibly icy sidewalk)

Assumption of risk vs contributory negligence

  • Assumption of risk emphasizes the plaintiff's knowledge and voluntary acceptance of the risk (playing a contact sport, participating in a high-risk adventure)
  • focuses on the plaintiff's own negligence contributing to their injury (texting while driving, ignoring warning signs)
  • Some jurisdictions have merged the two defenses under plaintiff's assumption of risk may be considered in determining the degree of fault attributed to each party

Effectiveness of risk assumption defense

  • Sports assumption of risk is often a strong defense, as participants are generally aware of inherent risks (injuries in boxing, collisions in ice hockey)
    • Defense may not apply if defendant's conduct goes beyond ordinary risks or if defendant intentionally causes harm (excessive violence, rule violations)
  • Employment assumption of risk has been limited due to workers' compensation laws and unequal bargaining power
    • May still apply in inherently dangerous occupations or where employee knowingly violates safety rules (firefighting, construction work)
  • Consumer products assumption of risk may apply if plaintiff misuses a product or ignores clear warnings (using a chainsaw improperly, disregarding safety instructions)
    • Manufacturers have a duty to design reasonably safe products and provide adequate warnings, limiting the defense's effectiveness (defective car brakes, insufficient drug labels)

Key Terms to Review (18)

Adventure sports: Adventure sports refer to physically demanding activities that often involve elements of risk and excitement, such as rock climbing, white-water rafting, and paragliding. These activities are typically pursued in natural settings and often challenge participants both mentally and physically, pushing them to confront their limits. The nature of adventure sports makes them a significant area of interest when discussing liability and the assumption of risk.
Assumption of Risk: Assumption of risk is a legal doctrine that asserts a person can be held responsible for the injuries they incur while voluntarily engaging in an activity that involves known risks. This concept is significant because it relates to how individuals may agree to take on certain dangers, potentially limiting the liability of others involved in those activities.
Comparative Fault Principles: Comparative fault principles are legal doctrines that allocate liability among parties based on their respective degrees of fault in causing an injury or damage. This approach recognizes that multiple parties can contribute to an accident, and it allows for a more equitable distribution of damages by reducing the recovery amount based on the injured party's own negligence.
Contact sports: Contact sports are competitive games in which participants physically engage with one another, often involving bodily contact as a fundamental aspect of the play. This definition highlights the inherent risks involved in these sports, where players may sustain injuries due to collisions, tackles, or other forms of physical interaction. The nature of contact sports raises important considerations about personal responsibility and the acceptance of risk by athletes and participants.
Contributory Negligence: Contributory negligence is a legal doctrine that prevents a plaintiff from recovering damages if they are found to have contributed to their own injury through their own negligence. This concept emphasizes that individuals have a responsibility to act with reasonable care for their own safety, and if they fail in this duty, it can significantly impact their ability to claim compensation.
Enforceability: Enforceability refers to the ability of a legal agreement or contract to be upheld in a court of law. A contract is enforceable when it meets all the essential elements required for legal validity, such as mutual consent, consideration, legality, and capacity. In the context of certain defenses, like assumption of risk, enforceability examines whether a party can legally claim a defense based on their prior knowledge and acceptance of a risk associated with an activity.
Express assumption of risk: Express assumption of risk refers to a legal doctrine where an individual knowingly and voluntarily agrees to accept the inherent risks associated with an activity, thereby waiving their right to sue for any resulting injuries. This concept is significant as it establishes that individuals cannot hold others liable for injuries sustained in activities they explicitly accepted the risks for, often through written agreements or verbal agreements.
Implied assumption of risk: Implied assumption of risk refers to a legal doctrine where a person is considered to have accepted the inherent risks associated with an activity simply by participating in it. This concept often comes into play in tort cases involving negligence, where a plaintiff's awareness and acceptance of potential dangers can limit or negate the liability of the defendant. It is crucial for understanding how courts evaluate fault and responsibility in injury claims related to recreational or hazardous activities.
Informed consent: Informed consent is the process by which a person voluntarily agrees to a proposed course of action, such as medical treatment or participation in research, after being fully informed of the risks, benefits, and alternatives involved. This concept is critical in establishing ethical standards, ensuring that individuals understand what they are consenting to and protecting their autonomy in decision-making.
Inherent Risks: Inherent risks refer to the dangers or potential hazards that are naturally associated with certain activities or situations, which cannot be completely eliminated even with safety measures in place. Understanding inherent risks is crucial in evaluating liability and the assumption of risk in various contexts, as participants may be expected to accept these risks when engaging in certain activities.
Liability waiver: A liability waiver is a legal document in which an individual voluntarily relinquishes their right to pursue legal claims for injuries or damages that may occur as a result of participating in an activity. This document is often used by organizations and businesses to protect themselves from lawsuits and claims arising from risks inherent in certain activities, such as sports or recreational events. It essentially shifts the responsibility for any potential harm away from the entity providing the activity.
Primary implied assumption of risk: Primary implied assumption of risk refers to a legal doctrine where a participant in an activity voluntarily accepts the inherent risks associated with that activity, thereby limiting the liability of the defendant. This concept emphasizes that some risks are so inherent to certain activities that individuals participating in them are considered to have consented to those risks, even if they did not explicitly express their acceptance. It highlights the importance of individual responsibility and choice in engaging in activities where certain dangers exist.
Public Policy: Public policy refers to the principles and guidelines that govern the actions of a government and its agencies. It reflects the societal values and beliefs about what is important for the community, influencing legal decisions, especially regarding issues of liability and risk. Public policy plays a crucial role in shaping laws and regulations that can impact how assumptions of risk are treated in various legal contexts.
Secondary implied assumption of risk: Secondary implied assumption of risk occurs when a plaintiff knowingly encounters a risk created by the defendant's negligence, thereby accepting that risk even if it was not intended. This concept emphasizes the plaintiff's awareness and voluntary acceptance of the potential dangers associated with an activity, particularly in situations where the defendant's conduct has contributed to the risk. Understanding this term is crucial in determining liability and defenses in tort cases, especially in the context of recreational activities or hazardous conditions.
Secondary Risks: Secondary risks refer to the additional dangers or hazards that may arise as a consequence of taking on certain activities or risks, particularly in situations where the individual has voluntarily accepted primary risks. These secondary risks are often not immediately apparent but can significantly impact the overall assessment of risk and liability.
Understanding the Risk: Understanding the risk refers to the knowledge and awareness individuals possess regarding potential dangers associated with an activity, which informs their decision to engage in that activity. This concept is pivotal in determining whether a person can assume responsibility for injuries sustained while participating in a risky activity, as it establishes if they were fully aware of the risks involved. It emphasizes the individual's ability to make informed choices based on their comprehension of the dangers they might face.
Voluntary Exposure: Voluntary exposure refers to the act of willingly and knowingly putting oneself in a situation that carries a risk of harm or injury. This concept is crucial in understanding how individuals assume responsibility for their own safety when they choose to engage in risky activities, which can impact legal liability in cases involving injury. By choosing to accept such risks, individuals may limit their ability to claim damages against others who might be responsible for those risks.
Waivers: Waivers are legal documents that release one party from liability for certain actions or events, often used in contexts where there is an inherent risk involved. They serve to inform participants of the risks and to secure their agreement not to hold the other party responsible for any resulting harm. Waivers can be critical in situations like sports, recreational activities, or any scenario where individuals may face potential injury.
