Sometimes a person or company that offers a risky service or product will ask a participant to sign a written contract. As part of such a risk-taking agreement, the applicant expressly agrees to bear the risk of injury. Risk assumption does not preclude recovery in cases where the defendant has broken the law or improperly increased the risks to the applicant beyond the risks associated with the activity. But there are exceptions to this rule. One of the main ones is California`s doctrine of “risk-taking.” The California Supreme Court established the doctrine in 1992 in a case called Knight v. Jewett. When the defendant`s negligence is ultimately a violation of a law protecting a certain class of persons, a plaintiff in that class is considered legally incapable of taking the risk. This is a “secondary” risk-taking where the defendant still has a duty of care to the applicant, but the applicant was aware of the risk caused by the defendant`s negligence and acted in spite of everything.  For example, an employer provides a defective machine to an employee, and because the worker knows the machine is defective, he continues to use it (albeit cautiously).  If the machine causes injury, the employer may have secondary responsibility for the risk defence.  In comparative negligence jurisdictions, secondary risk-taking is used as a factor that the jury may consider in the allocation of fault and not as a complete defense.
 There are two types of risk-taking: explicit and implicit. The applicant`s knowledge of the dangers and his voluntary decision to expose himself to them are measured subjectively. See Dillard v. Little League baseball, 55 app. Div.2d 477 (1977). In other words, it is judged on what the applicant knew personally and on what the applicant personally intended to do. The reasonable man test is not used here. What worries us is what went through the mind of this particular complainant. Even if, in our previous example, Dave had not signed a contract to take the risks, it is possible that he could not recover from injuries because, as an enthusiastic bungee rider, he may consider that he knew the risks of jumping and that he voluntarily accepted them. Explicit risk-taking exists when the applicant expressly accepts the danger, whether by oral or written agreement.
 For example, a gym requires its members to sign a disclaimer that states that the gym is not legally responsible for injuries when the member drops heavy weights on themselves.  However, the signed waiver of liability is not a general exclusion of liability for operators of a hazardous activity.  The specific risk giving rise to the harm must have been known to and assessed by the applicant so that the primary risk-taking can be applied appropriately.  Courts often refuse to impose a blanket waiver of liability if it does not inform the signatory of the specific risk giving rise to the breach.  In addition, explicit risk-taking cannot exempt a defendant from liability for ruthless conduct (negligence only).  Although George voluntarily took charge of the risk of injury, the Home Center still owes it to customers to exercise due diligence so as not to injure them. None of the parties is therefore innocent. A jury will have to decide on the allocation of responsibility for George`s violation. Under federal rules of civil procedure, risk-taking is a positive criminal law defense that a defendant can bring in a negligent action. . . .
