The Supreme Court's unanimous decision in Montgomery v. Caribe Transport II, LLC is a major development for brokers, shippers, carriers, and insurers because it removes a preemption defense that had blocked negligent-hiring and negligent-selection claims in some jurisdictions. Across transportation-focused law firm alerts and trade coverage, the emerging consensus is that the decision does not make brokers automatically liable for every crash, but it does make broker vetting practices, internal policies, and documentation central to future litigation.
What the Court Held
In Montgomery, the Court held that a state common-law claim alleging that a broker negligently hired an unsafe motor carrier falls within the safety exception to the Federal Aviation Administration Authorization Act of 1994 (FAAAA). The FAAAA broadly preempts state laws related to a broker's prices, routes, or services, but it also preserves a state's safety regulatory authority with respect to motor vehicles. Writing for a unanimous Court, Justice Barrett reasoned that requiring a broker to exercise ordinary care in selecting a carrier "concerns" the motor vehicles used to transport freight, bringing negligent-hiring claims within the statutory exception.
That holding reverses the Seventh Circuit and resolves a long-running split over whether such claims were categorically preempted. Before Montgomery, broker defendants often relied on favorable precedent in some circuits to argue that negligent-selection claims interfered with federally protected broker services and therefore could not proceed under state law. The Court has now largely closed that route.
The Converging View from Industry Alerts
The common thread across recent alerts is that the decision expands exposure but stops short of imposing strict liability on brokers. Firms covering the decision are emphasizing three points.
First, negligent-hiring and negligent-selection suits against brokers are expected to increase because plaintiffs no longer face the same threshold preemption obstacle in many cases. Second, the ordinary elements of negligence still matter, especially whether the broker had reason to know of safety problems and whether the alleged vetting failure proximately caused the injury. Third, courts and litigants are likely to focus heavily on the broker's actual carrier-selection process rather than abstract arguments about federal deregulation policy.
That framing aligns with the concerns flagged in Justice Kavanaugh's concurrence, joined by Justice Alito. The concurrence acknowledged the brokers' concerns about litigation costs and economic effects as "legitimate and weighty," while concluding that any broader shield from state tort suits must come from Congress rather than judicial expansion of preemption. For regulated parties, that means the operational response matters now even if the legislative debate continues.
Why Broker Vetting Now Matters More
The immediate practical consequence of Montgomery is that broker due diligence will move to the center of discovery and trial strategy. Plaintiffs will likely seek internal carrier-approval criteria, onboarding checklists, training materials, emails, exception approvals, and records showing what FMCSA data was reviewed before the load was tendered.
That means brokers should revisit whether their written procedures are specific enough to be defensible and simple enough to be followed consistently. Policies that reference safety review in general terms but do not define escalation triggers, disqualifying indicators, or exception authority may create unnecessary litigation risk if personnel apply them unevenly. A well-documented vetting record will not eliminate claims, but it will be far more useful than relying on a preemption argument that no longer carries the same force.
Contract and Insurance Implications
Another theme emerging from post-decision commentary is that contract language and insurance structure will receive renewed attention. Broker-carrier agreements are likely to include more detailed safety representations, notice obligations for rating downgrades or serious violations, audit rights, and more pointed indemnity language directed to loss arising from unsafe operations.
Insurers are also likely to scrutinize underwriting submissions more carefully, especially where a broker uses smaller carriers, high-risk lanes, expedited loads, or carriers with mixed safety histories. Even where coverage remains available, the market may respond with higher premiums, tighter exclusions, or more detailed questions about vetting controls and record retention. Shippers may feel the impact as well, whether through revised service agreements, more robust compliance certifications, or rate adjustments reflecting increased liability and defense costs.
What Transportation Stakeholders Should Do Now
For brokers, the most immediate step is to test whether current carrier-selection practices match what internal manuals and contracts say they require. For shippers, this is the right time to review how broker agreements allocate responsibility for carrier screening, information sharing, indemnity, and insurance. For carriers, the case is another reminder that publicly visible safety performance can affect not only enforcement exposure but also access to freight.
The broader lesson from Montgomery is straightforward: the litigation focus has shifted from whether a negligent-hiring claim may be filed to whether the broker's conduct was reasonable under the circumstances. In that environment, companies that can show disciplined vetting, clear escalation standards, and consistent documentation will be better positioned than those still relying on old assumptions about FAAAA preemption.
