People often confuse this with the risk-utility test, but they ask different questions. The consumer expectation test looks at whether a product was more dangerous than an ordinary user would reasonably expect when used in a normal or foreseeable way. The risk-utility test, by contrast, weighs whether a product's design risks outweighed its benefits and whether a safer practical design was available.

That difference matters after a serious injury. If a product failed in a way that would shock an average buyer - like a seat belt unlatching during a crash or a ladder collapsing under ordinary use - the consumer expectation test can be a direct way to show a defect without needing highly technical engineering proof. It focuses on what a reasonable consumer would expect, not just what a manufacturer says was acceptable.

In a product liability claim, the right test can shape what evidence matters, how hard the case is to prove, and whether expert testimony becomes central. In Hawaii, that can be especially significant when delayed emergency care on rural islands or road closures from flash floods make injuries worse after a product failure. Deadlines still apply: Hawaii Revised Statutes § 657-7 (2024) generally gives an injured person two years to file a claim for personal injury, including many product-related cases.
