Explanation:

Last Clear Chance Definition

The last clear chance doctrine is used to compensate for the contributory negligence which means it helps when a plaintiff fully contributed to their injury through their own negligence.

In this case a negligent plaintiff is required to provide evidence that the defendant was the one who had the last chance to act and change the situation to prevent harming the plaintiff but still they did not act on that chance.

This means that eventhough the plaintiff was completely negligent but the defendant had the chance which was not available to the plaintiff at that moment to impact the situation positively.

The plaintiff evidence must show that they were unable to save themselves,the defendant had knowledge of this danger and the defendant was in a reasonable state to act and prevent injury to the plaintiff.
