Risk utility test

What is the risk utility test?

The risk utility test is New Jersey's primary framework for evaluating design defect claims, weighing a product's inherent dangers against its genuine benefits and utility.

It represents a more sophisticated analytical approach than the simpler consumer expectation test, and it is considerably better suited to complex products where ordinary consumers genuinely lack the technical knowledge to meaningfully evaluate design choices themselves.

The test asks not merely whether a product was dangerous, but whether that specific danger could reasonably have been avoided or meaningfully reduced without unreasonably impairing the product's genuine usefulness.

It is the dominant framework in most modern, complex product liability litigation.

What specific factors does the test weigh?

Several factors are generally balanced together in this analysis, though no single factor is automatically decisive on its own.

• The product's overall usefulness and genuine desirability to users
• The likelihood and probable seriousness of resulting injury
• The availability of a genuinely feasible safer alternative design
• The manufacturer's actual ability to eliminate the danger without impairing usefulness
• The user's own ability to avoid the danger through reasonable care
• The feasibility of spreading the cost of any added safety measures

Why does a safer alternative design matter so significantly?

Because it transforms an abstract complaint about inherent danger into a concrete, specific comparison the jury can genuinely evaluate against what was actually feasible.

Demonstrating that a specific, technically and economically feasible alternative design existed, and would have prevented the specific injury without ruining the product's genuine usefulness, is generally the single strongest evidence in these cases.

Evidence that competitors already used a safer design, or that the manufacturer itself considered and rejected such an alternative, is particularly persuasive to a jury.

How does this differ practically from the consumer expectation test?

The consumer expectation test asks what an ordinary user would reasonably anticipate about the product's safety, which works well for simple, familiar products.

This test instead requires a more technical, expert driven analysis of engineering tradeoffs and genuinely feasible alternatives, which is considerably better suited to complex products like vehicles, machinery and medical devices.

New Jersey courts sometimes consider elements of consumer expectation within this broader risk utility weighing itself, particularly regarding what an ordinary user might reasonably have anticipated about a specific risk.

Common questions

Do I need an expert witness for a risk utility claim?

Generally yes. Establishing the specific factors, and particularly a feasible alternative design, typically requires qualified engineering or technical expert testimony.

Does the manufacturer have to prove there was no safer alternative?

The burden generally falls on you to establish the specific elements, including where applicable that a feasible alternative design actually existed and was reasonably available.

Can a product pass this test even though it is genuinely dangerous?

Yes, potentially. Some products are inherently dangerous by their very nature, and the analysis considers whether that specific danger could reasonably have been further reduced without eliminating the product's genuine usefulness.
