  1. AThe distributor failed to properly inspect the plank before selling it.
  2. BThe worker assumed the risk by working on scaffolding.
  3. CThe worker modified the scaffolding plank against instructions.
  4. DThe manufacturer exercised all reasonable care in the plank's production.
Show answer & explanation

Correct answer: C. The worker modified the scaffolding plank against instructions.

In strict products liability, a manufacturer is generally liable for injuries caused by a defective product, regardless of fault. However, if the plaintiff's own actions, such as modifying the product in an unforeseeable way, directly caused the injury, it can serve as a defense (misuse or alteration).

Why the other options are wrong

  • A. The distributor's negligence does not typically absolve the manufacturer of strict liability for a manufacturing defect.
  • B. Working on scaffolding, while inherently risky, does not automatically constitute assumption of risk against a defective product unless the worker knew of the specific defect.
  • D. The essence of strict products liability is that reasonable care in production is not a defense if the product is defective and caused injury.

Assumption of Risk (Products Liability)

A defense in products liability where the plaintiff voluntarily and knowingly encountered a known risk posed by a defective product.

  • Plaintiff must have actual knowledge of the defect and the risk.
  • Plaintiff must voluntarily encounter the known risk.
  • Often related to product misuse or alteration.

Memory trick: Product Liability: Defenses block the defect.
