California operates under a “comparative negligence” system when it comes to insurance claims. Calif. Civil Code (CIV) §1714 states that, “Everyone is responsible, not only for the result of his or her willful acts, but also for an injury occasioned to another by his or her want of ordinary care or skill in the management of his or her property or person, except so far as the latter has, willfully or by want of ordinary care, brought the injury upon himself or herself.” Under this law, if a car accident claim is taken to trial, the percentage of fault will be calculated for all drivers involved. If the plaintiff, or victim, is found to be partially at fault, the amount of damages awarded to them will be reduced by the percentage of fault.
