What are the facts?
The plaintiff, Larsen, was driving a Chevrolet Corvair when his vehicle was involved in a head-on collision. During the impact, the steering assembly and column allegedly acted as a rigid spear, being driven rearward into the passenger compartment and causing severe head injuries. Larsen did not claim that any defect in the vehicle caused the collision itself. Instead, he alleged that General Motors negligently designed the vehicle by failing to incorporate reasonably safe, available features—such as an energy-absorbing or collapsible steering column—that would have reduced or prevented the severity of his injuries during the collision. The district court ruled in favor of General Motors on the theory that a manufacturer has no duty to make a vehicle accident-proof and that liability cannot arise when a defect did not cause the initial crash, relying on contrary precedent. Larsen appealed.
What is the legal issue?
Whether an automobile manufacturer owes a duty to design a vehicle to be reasonably safe in foreseeable collisions and can be held liable for enhanced injuries caused by an unreasonably dangerous design even when the defect did not cause the initial accident.
What rule applies?
A manufacturer has a duty to use reasonable care in the design of its product to avoid subjecting users to an unreasonable risk of injury in foreseeable uses and misuses, including the foreseeable occurrence of automobile collisions. While the manufacturer is not an insurer and need not design an accident-proof vehicle, it may be liable in negligence (and, by later doctrine, in strict liability) for design defects that proximately cause or enhance occupant injuries during a collision. Liability is limited to the extent of the enhanced injuries that are attributable to the design defect, and difficulties in apportioning damages do not bar recovery.
What did the court hold?
Yes. Automobile manufacturers have a duty to design vehicles that are reasonably safe in the event of foreseeable collisions, and they may be held liable for injuries enhanced by negligent design even if the defect did not cause the accident. The judgment for the manufacturer was reversed and the case remanded.
What is the reasoning?
The court began by recognizing that collisions are statistically inevitable in the normal use of automobiles. Because accidents are foreseeable incidents of ordinary driving, a manufacturer's duty of reasonable care extends to designing vehicles that mitigate, rather than exacerbate, occupant injuries during a crash. The court rejected the categorical proposition that a manufacturer's duty cannot extend beyond preventing accidents in the first place, emphasizing that a vehicle's "intended use" includes the realities of highway travel where collisions routinely occur. The court specifically disapproved the contrary reasoning in Evans v. General Motors, which denied liability unless the defect caused the initial collision. That approach, the Eighth Circuit explained, is artificially narrow, ignores foreseeability, and undermines incentives to incorporate safety innovations. Designers must exercise ordinary care to avoid unreasonable risks of injury from foreseeable impacts; this does not impose insurer-like liability or require accident-proof vehicles. Rather, it obliges manufacturers to adopt reasonably available, cost-effective design measures—such as energy-absorbing steering columns—that would lessen harm. On causation and damages, the court recognized the concept of "enhanced injuries" or the "second collision" between the occupant and the vehicle interior. The manufacturer is liable only to the extent the defect aggravated or increased the plaintiff's injuries beyond those that would have resulted from the collision absent the defect. Although separating out the degree of enhancement may be complex, difficulties of apportionment do not defeat a valid claim. The defect need only be shown to be a proximate cause of the additional harm. By reinstating the claim, the court permitted a jury to evaluate evidence of design defect, feasibility of safer alternatives, foreseeability of collisions, and the extent of injury enhancement.
Why is this case significant?
Larsen is the leading case establishing the crashworthiness doctrine, now widely accepted across jurisdictions. It teaches core tort concepts—duty based on foreseeability, design-defect negligence, proximate cause for enhanced injuries, and apportionment of damages—within the practical context of automotive safety. The case catalyzed industry-wide adoption of occupant-protection features (e.g., collapsible steering columns, energy-absorbing interiors, later airbags and improved restraint systems) and remains a cornerstone in products-liability courses and litigation involving safety design, risk-utility balancing, and the limits of manufacturer responsibility.
What does "crashworthiness" or the "second collision" doctrine mean?
Crashworthiness refers to a manufacturer's duty to design a vehicle that reasonably protects occupants from enhanced injuries when a collision occurs. The "second collision" describes the impact between the occupant and the vehicle's interior or safety systems during a crash. Under this doctrine, a manufacturer can be liable for design defects that exacerbate injuries even if the defect did not cause the initial accident.
Did Larsen impose strict liability or analyze negligence?
Larsen primarily analyzed negligence, focusing on the duty to use reasonable care in design. The court's reasoning—particularly that collisions are foreseeable and design choices must avoid unreasonable risks—later informed strict-liability design-defect claims in many jurisdictions. Today, the crashworthiness principle applies in both negligence and strict-liability frameworks, depending on the jurisdiction.
How does causation work in crashworthiness cases after Larsen?
The plaintiff must prove that the design defect was a proximate cause of enhanced injuries beyond those that would have resulted from the collision alone. While apportioning damages between initial impact and defect-caused enhancement can be challenging, such complexity does not bar recovery. Juries may rely on expert testimony, accident reconstruction, and biomechanical evidence to estimate the defect's contribution.
Did Larsen require manufacturers to make accident-proof vehicles?
No. The court expressly stated that manufacturers are not insurers and need not produce accident-proof cars. The duty is to exercise reasonable care by adopting feasible, safer designs that reduce unreasonable risks of injury in foreseeable collisions. The standard balances safety benefits, technological feasibility, and cost.
How did Larsen treat Evans v. General Motors (7th Cir.)?
Larsen rejected Evans's narrow view that liability cannot attach unless the defect caused the initial collision. The Eighth Circuit found that approach inconsistent with foreseeability and modern tort principles. By doing so, Larsen became the leading authority for recognizing enhanced-injury liability in automotive design cases.
What practical impact did Larsen have on automotive design and litigation?
Larsen spurred broader adoption of occupant-protection features (e.g., energy-absorbing steering columns, improved dashboards, restraint systems) and reframed litigation strategy to focus on injury mitigation. Plaintiffs routinely marshal evidence of feasible alternative designs and quantify enhanced injuries, while manufacturers emphasize risk-utility tradeoffs, compliance with standards, and limits on apportionable damages.
