Can Federal Safety Standards Block Your Defect Claim?

A defense lawyer tells you the vehicle met every applicable federal safety standard, so your case is finished. Compliance may strengthen the manufacturer’s defense, but it does not automatically bar a Texas product liability claim.

Two separate rules can affect the case. Federal preemption may end a claim in narrow circumstances. A Texas statutory presumption can shift the burden to you while leaving the claim open.

How Federal Compliance Affects Liability

Under 49 U.S.C. 30102(a)(10), a motor vehicle safety standard is a minimum standard for performance.

The savings clause at 49 U.S.C. 30103(e) then states that compliance “does not exempt a person from liability at common law.” Manufacturers also certify their own compliance under 49 U.S.C. 30115(a).

Most defect claims follow an ordinary Texas crash, where compliance raises the separate risks of a narrow federal preemption defense and the Texas compliance presumption. Only the federal defense can end the claim.

How Conflict Preemption Applies

A Federal Motor Vehicle Safety Standards (FMVSS) preemption defense is narrower than it sounds. Express preemption does not apply to common-law lawsuits.

In Geier v. American Honda Motor Co., 529 U.S. 861 (2000), the Supreme Court read the savings clause as narrowing the express preemption clause so that it does not cover common-law suits. A broader reading would leave few, if any, state tort actions for the savings clause to save.

The savings clause does not prevent conflict preemption. A claim may still be preempted if enforcing state law would interfere with a federal objective. This is known as implied conflict preemption or obstacle preemption.

Texas courts read it the same way. In MCI Sales & Service, Inc. v. Hinton (Tex. 2010), obstacle preemption was the only preemption theory advanced.

A federal standard that deliberately allows manufacturers to choose among designated options may preempt a state claim that would effectively require one option. The same analysis governs heavy vehicle defect claims.

The Dividing Line Between a Deliberate Mix & a Plain Floor

Obstacle preemption applies in a narrow situation. A federal agency deliberately gave manufacturers several options because it wanted a mix of systems on the road, and the state-law claim would effectively require every manufacturer to choose one.

Deliberate Variety in Geier

The 1984 version of 49 C.F.R. 571.208 let manufacturers choose among passive restraint systems and phased it in gradually. The agency wanted manufacturers to use different systems while it evaluated costs, safety risks, and comparative data.

A state-law duty requiring airbags would have pushed every similar vehicle toward one device and interfered with that federal objective. The Court therefore held that the claim was preempted.

Regulatory Choice in Williamson

Williamson v. Mazda Motor of America, Inc., 562 U.S. 323 (2011) involved the same standard and a similar choice. The 1989 version let manufacturers install either a lap belt or a lap and shoulder belt at rear inner seats. The Court held the suit was not preempted because providing that seatbelt choice was not a significant objective of the regulation.

By 1989, the agency was not trying to maintain a mix of restraint systems and believed the lap-and-shoulder belt offered greater safety. Its decision to permit lap belts was based primarily on cost.

Justice Sotomayor summarized the distinction in her concurrence. Giving manufacturers a choice is not enough. The agency must have intended that choice to advance a federal objective.

The lap-only option for rear seats is no longer available in vehicles manufactured on or after September 1, 2007. FMVSS 208 now generally requires lap-and-shoulder belts in rear seats. When an alleged defect contributes to a fatal crash, the same analysis may affect a wrongful death claim.

How the Texas Compliance Presumption Works

Federal preemption can end a claim. Texas law creates a separate compliance presumption that shifts the burden to the claimant but can still be overcome.

What the Presumption Requires

Tex. Civ. Prac. & Rem. Code 82.008 creates a rebuttable presumption that a manufacturer is not liable when the formulation, labeling, or design complied with a mandatory federal standard.

Kia Motors Corp. v. Ruiz (Tex. 2014) identifies three requirements. The manufacturer must show compliance with a mandatory federal standard, that the standard applied when the product was manufactured, and that the standard governed the product risk that allegedly caused the harm.

The third requirement limits when the presumption applies. In Kia Motors, the presumption did not apply because the crash-test requirements did not address the alleged risk of an airbag failing to deploy reliably.

Section 82.008 provides two ways to overcome the presumption. The claimant may show that the federal standards did not adequately protect the public from unreasonable risks or that the manufacturer withheld or misrepresented information relevant to the agency’s decision. The presumption does not cover manufacturing defects, even when the company followed federally mandated quality-control procedures.

The Milburn Limit on Rebuttal

American Honda Motor Co. v. Milburn, No. 21-1097 (Tex. June 28, 2024) shows how heavy that burden is. A third-row passenger used only the shoulder portion of a ceiling-mounted seat belt and suffered catastrophic injuries when the vehicle rolled. FMVSS 208 expressly permitted the design.

The Texas Supreme Court held that the presumption applied and that the evidence did not overcome it. The Court reversed the lower judgment and ruled for Honda.

Whether a design is defective and whether the standard it met is inadequate are distinct inquiries. Rebuttal takes more than a risk-benefit conclusion about the design at issue.

The Court said relevant evidence could include problems with the agency’s decision-making process or later developments such as new technology or new risk data. It did not define the full limits of that second route.

The Court did not address Honda’s preemption argument, so Milburn concerns the Texas compliance presumption rather than federal preemption.

Building a Defect Claim Around the Standard’s Limits

The claim’s strength depends on how closely the federal standard matches the alleged defect.

Reviewing What the Standard Requires

Start by identifying what the standard requires and what it merely permits. Then review the rulemaking record to determine whether the agency intended to preserve a mix of designs or establish a minimum requirement. When the standard establishes a minimum, the savings clause may allow a claim that the manufacturer should have provided greater protection.

The standard may not address whether the chosen system performed correctly or whether the product had manufacturing, assembly, testing, or warning defects. Milburn shows the limit. The claimant challenged the usability of a design expressly permitted by the regulation and failed to overcome the Texas compliance presumption. When the compliant design itself is challenged, the evidence must show why the federal standard provided inadequate protection.

The Evidence That Decides These Cases

• The version of the standard in force on the vehicle’s date of manufacture.
• The rulemaking record behind it, including the 2004 rear belt rulemaking.
• The manufacturer’s certification and internal compliance-testing records.
