Back v. Wickes Corp.
Facts
Four students died when a borrowed motor home struck a cable fence on the Massachusetts Turnpike, overturned, caught fire, and exploded; a passing truck driver, Mead, was injured while attempting a rescue. The plaintiffs claimed the motor home was negligently designed and unmerchantable because design choices made the fuel tank vulnerable and the vehicle highly flammable in a collision. The defendants disputed defect and introduced evidence that the vehicle conformed to prevailing industry and safety standards. At trial, the judge instructed the jury that misuse or abuse of the product would be a complete defense to the warranty claims.
Issue
Whether the trial judge erred by instructing the jury on misuse in the warranty claims where there was no evidence of unforeseeable misuse, and whether the judge erred regarding the relevance of industry custom and the negligence standard. More specifically, the case asked whether a collision with a highway guardrail could be treated as an abnormal or extraordinary use relieving the manufacturer of warranty liability.
Rule
In a Massachusetts warranty action for personal injuries, the ordinary purposes of goods include both intended uses and reasonably foreseeable uses. A manufacturer is not liable for unforeseeable misuse or bizarre, unforeseeable accidents, but it must design against reasonably foreseeable risks in the environment where the product will be used; thus, a misuse instruction is improper absent evidence of unforeseeable misuse. In design-defect warranty cases, evidence of conformity with industry practice is relevant though not dispositive, and negligence is measured by the conduct of the ordinary reasonably prudent manufacturer in like circumstances.

At trial, the manufacturer asks for a jury instruction that striking a median is an "extraordinary or unusual" use of the van and therefore a complete defense to warranty liability. How should the judge rule?
