The May 2026 Supreme Court ruling in Montgomery v. Caribe Transport II changed the legal landscape for truck accident victims in a single unanimous decision. For years, freight brokers hid behind federal preemption to avoid liability when they placed unsafe carriers on the road. That shield is gone. Today, every broker negligence damages truck accident claim must be evaluated through a new multi-tier damages framework — one that stacks carrier liability on top of broker-specific exposure and applies state negligence law to determine what a case is actually worth.
This calculator-style guide walks injury victims, families, and legal teams through each layer of the damages ladder: the base carrier liability tier, the negligent hiring multiplier that brokers now face, the proof required to unlock broker culpability, and how your state’s comparative fault rules either compress or expand the final settlement range.
What Montgomery v. Caribe Transport II Actually Changed in 2026
Before the Supreme Court’s 9-0 ruling on May 14, 2026, brokers routinely filed motions to dismiss broker negligence claims under the Airline Deregulation Act’s preemption provision, incorporated into the Federal Aviation Administration Authorization Act (FAAAA). Courts were split on whether the FAAAA’s safety exception — which preserves state laws “with respect to motor vehicle safety” — allowed negligent hiring lawsuits against brokers. Montgomery v. Caribe Transport II resolved that split decisively: the safety exception applies, federal preemption does not bar state-law negligence claims against freight brokers, and plaintiffs may now pursue broker liability in every jurisdiction.
The practical effect is immediate. Insurers can no longer price broker exposure at zero on the assumption that a preemption motion will end the case. Litigation teams must now evaluate broker negligence damages truck accident exposure as a quantifiable line item from the moment a claim is filed. Importantly, Justice Kavanaugh’s concurring opinion — joined by Justice Alito — clarified that brokers will not routinely face liability and that injured parties must still prove all traditional tort elements under state law. That caveat matters for case valuation: Montgomery opens the courthouse door, but it does not guarantee a verdict. The FAAAA preemption statute at 49 U.S.C. § 14501 and its safety exception are now interpreted to leave brokers fully exposed to state tort law when they carelessly select carriers, setting the stage for more complex litigation with higher discovery exposure across the board.
The Damages Ladder: How Broker Liability Stacks on Top of Carrier Liability
Tier One: Base Carrier Liability ($750K–$2M)
Every truck accident settlement analysis begins with the motor carrier’s direct liability. Federal minimum insurance requirements for large commercial trucks are set at $750,000 for most general freight carriers under 49 C.F.R. Part 387. In practice, catastrophic injury cases — spinal cord damage, traumatic brain injury, wrongful death — routinely push carrier-side settlements to $1.5M–$2M or higher before any broker tier is added. A 2025 Los Angeles wrongful death verdict involving a big rig on the 405 Freeway reached $85 million at the carrier level alone, illustrating the ceiling that serious cases can approach even before broker exposure is layered in.
