Liability & Fault

What is Proximate Cause?

The primary or legal cause of an injury that is sufficiently related to the harm to justify holding the defendant responsible, even if other factors also contributed.

Understanding Proximate Cause

Proximate cause requires that the injury be a foreseeable consequence of the defendant's actions. It is distinguished from actual cause (but-for causation) because it limits liability to harms that are within the scope of the risk created by the defendant's conduct. A defendant may be the actual cause of an injury but not the proximate cause if the harm was too remote or unforeseeable.

Examples

  • 1Running a red light is the proximate cause of injuries in the resulting collision
  • 2Leaving a wet floor unmarked is the proximate cause of a customer's fall
  • 3A defective brake system is the proximate cause of a rear-end accident
