When establishing causation, one must further look at the three stages of causation to determine the extent of negligence, as follows:
Absolute Causation - This stage is directly related to cause-in-fact. It means a cause is required and reasonable enough to bring about the end result.
Conditional Causation - This stage is directly related to proximate cause. It implies that, while a cause is required, it may not always be sufficient to support the end result.
Contributory Causation - This causation stage refers to how each party's actions contributed to the accident and the plaintiff's injuries.
