Final answer:
The statement that if a plaintiff's behavior contributed to their injury it is called comparative negligence is true. This legal doctrine adjusts damages based on the plaintiff's share of fault.
Step-by-step explanation:
If the behavior of the plaintiff helped to cause their injury, this is indeed referred to as comparative negligence. The concept of comparative negligence is grounded in the principle that, while the defendant may be at fault for the plaintiff's injury, the plaintiff may have also played a role in causing their own harm. In cases where comparative negligence is found, the damages may be reduced based on the plaintiff's percentage of fault. An example of such a situation might be if a driver, who is speeding, is hit by another vehicle that ran a red light. In this case, both parties have contributed to the cause of the accident.
