Stark v. Ford Motor Co. addressed a product-liability defense based on how a restraint was used; it did not create a general rule that every seat-belt issue defeats an injury claim.

A restraint dispute can involve traffic-law compliance, ordinary nonuse, incorrect routing, child-restraint installation, alleged product modification, product design, warnings, crash forces, occupant movement, or medical causation. The applicable rule depends on the claim and evidence.

The Stark dispute involved shoulder-belt routing

In the opinion reported in Stark v. Ford Motor Co., children were injured after a Ford Taurus accelerated and struck a light-pole base. Evidence indicated that one child’s shoulder belt had been placed behind her back. The plaintiffs alleged that the restraint system enhanced injuries; Ford asserted North Carolina’s alteration-or-modification defense.

The North Carolina Supreme Court held that the person alleged to have modified the product did not have to be a party to the lawsuit for the statutory defense to apply. It read the statute to cover an alteration or modification by anyone other than the manufacturer or seller when the remaining requirements are met.

G.S. 99B-3 requires more than the word misuse

G.S. 99B-3 bars manufacturer or seller liability when an alteration or modification by another party was a proximate cause of the injury, death, or property damage, subject to the statute’s stated exceptions. The statute defines alteration or modification to include changes in design, formula, function, or use from what was originally designed, tested, or intended, as well as failure to observe routine care and maintenance.

  • Identify the manufacturer, seller, vehicle, seat, seating position, restraint system, component, child seat or booster, and person alleged to have changed its use
  • Identify the designed and instructed use from the correct model-year manual, restraint label, child-seat manual, warnings, testing, and other admissible product evidence
  • Document the actual belt routing, latch, webbing, pretensioner, load limiter, anchor, seat, airbag, occupant position, clothing, and any post-event change
  • Analyze whether the alleged change was a proximate cause of the claimed injury rather than assuming causation from incorrect use alone
  • Evaluate the statutory exceptions and every other asserted product theory and defense separately

Ordinary seat-belt nonuse has a separate evidence rule

G.S. 20-135.2A(d) states that evidence of failure to wear a seat belt is not admissible in a criminal or civil proceeding except for the purposes specified in that statute. Stark involved an asserted Chapter 99B product-modification defense and restraint routing, not merely an argument that an occupant failed to buckle up.

Do not assume that subsection (d) answers every question about product alteration, correct routing, child-restraint use, occupant kinematics, defect, causation, or damages. The legal purpose for which the evidence is offered remains important.

Preserve the physical and digital crash record

  • Original scene, vehicle, interior, seat, restraint, child seat, buckle, latch plate, webbing, anchor, airbag, and occupant-position photographs
  • Vehicle event-data and restraint-control data when available, with collection method, software version, report, and chain of custody
  • Police, fire, EMS, witness, parent, occupant, technician, and medical accounts compared by time and purpose
  • Vehicle and restraint manuals, labels, recalls, bulletins, testing, repair, inspection, maintenance, purchase, and ownership records
  • Injury mechanism opinions tied to the actual occupant, restraint geometry, crash pulse, alternative explanations, and medical evidence
