You may see this in a denial letter, expert report, or settlement talk as a claim that a product was "not unreasonably dangerous under the risk-utility test." Stripped down, that means the product's design is judged by balancing its benefits against its dangers. A court or jury may look at questions like: How likely was the harm? How severe could it be? Was a safer design available? Would that safer option have been practical and affordable without wrecking the product's usefulness?

A lot of people hear "there was a warning" or "accidents happen" and assume that ends the case. It does not. The test is not a free pass for a manufacturer just because a product has some value or because users are expected to be careful. If a safer design was realistic and the danger was avoidable, a design defect claim may still be strong. That matters in crashes and injury cases where a product fails under predictable conditions, including bad-weather situations like sudden hydroplaning in a Hawaii rain squall.

For an injury claim, this test often becomes a fight between engineers, safety experts, and company documents. The maker may argue user error; the injured person may point to a defective design. In Hawaii, fault can reduce or block recovery under the state's modified comparative fault rule, Haw. Rev. Stat. § 663-31 (1969): recovery is barred if the injured person is more than 50% at fault.
