In automotive product liability cases, the vehicle’s compliance with applicable federal motor vehicle safety standards is often presented as evidence tending to show the design was not defective. In many states, such compliance does not exempt the manufacturer from liability at common law, but under Texas law, the Texas Supreme Court has proclaimed it does under certain circumstances. This will be contrasted with a more recent case in which the Pennsylvania Supreme Court explicitly held that evidence of a defendants’ compliance with industry or governmental safety standards is inadmissible in product liability actions.
