On May 14, the Supreme Court issued a unanimous decision in Montgomery v. Caribe Transport II, LLC. The case directly addressed freight broker liability and has been widely covered in trucking industry media. The ruling itself is freight-specific, but the underlying legal reasoning has structural relevance to a model the chauffeured transportation industry uses every day: affiliate work.
The ruling reaches every business that puts a driver on the road. While freight and shipping brokers face the most direct impact, limousine, motorcoach, and passenger transport operators face structural parallels they need to understand. Delivery and last-mile operations, warehousing and logistics yards, and millions of service and trades fleets—construction, HVAC, plumbing, electrical, landscaping, roofing, home health, real estate—also face exposure under the same underlying legal doctrine. Insurance underwriters will reprice the risk across all of them. The compliance story is much larger than any single category of carrier, and the practical implications are worth understanding clearly.
The headlines captured one slice. The ruling reached the whole industry.
The Ruling in Brief
Shawn Montgomery was severely injured in 2017 when his parked tractor-trailer was struck by another truck operated by Caribe Transport II, a motor carrier with a conditional safety rating. The shipment had been arranged by freight broker C.H. Robinson Worldwide. Montgomery sued, alleging that C.H. Robinson had negligently hired the carrier given the carrier’s known safety problems.
The Seventh Circuit had previously held that the Federal Aviation Administration Authorization Act (FAAAA) preempts negligent hiring claims against freight brokers. The Supreme Court unanimously reversed. Justice Amy Coney Barrett, writing for the Court, held that the FAAAA’s safety exception preserves state common-law negligent hiring claims because such claims concern motor vehicle safety. Justice Brett Kavanaugh filed a concurring opinion, joined by Justice Samuel Alito.
The practical effect for freight brokers is direct: they can no longer use federal preemption to dismiss negligent hiring claims at the threshold. Such claims now proceed in state court on the merits.
Why Our Industry Should Pay Attention
The ruling itself does not directly apply to chauffeured transportation operations. Passenger transportation is governed by a different preemption provision, and operators in this industry have not generally relied on FAAAA preemption as a defense. However, the structural parallel between freight brokerage and limousine affiliate work is what makes the ruling worth understanding.
When a limo operator accepts a booking and contracts with an affiliate operator in another market to perform all or part of the service, the originating operator is performing a function comparable to that of a transportation broker. The Supreme Court has now endorsed the underlying legal reasoning that supports negligent hiring claims against intermediaries who select unsafe carriers. Plaintiffs’ attorneys may seek to extend that reasoning to passenger transportation in future litigation.
Operators in this industry participate in the affiliate economy as both senders and receivers of work. Compliance documentation matters on both sides of every transaction: when selecting an affiliate and when being selected as one.
The Value of the Relationship-Based Network The chauffeured transportation industry’s affiliate network is built on decades of professional relationships, direct knowledge of partner operators’ standards, and reputational accountability within a connected industry community. These factors represent substantive due diligence with real legal and practical value.
The point of strengthening compliance documentation is not to replace established relationships with cold transactional vetting. It is to add a layer of verifiable evidence that supports the professional judgment already embedded in those relationships. The personal relationship answers why an operator chose a particular affiliate. The documentation answers what evidence supports that the choice was reasonable. Together, they form a stronger position than either provides alone.
Practical Steps for Operators
Operators may find the following framework useful for evaluating their own position:
❱ Review current affiliate vetting practices and identify documentation gaps.
❱ Update affiliate agreements to include compliance representations and provisions for ongoing documentation exchange.
❱ Maintain current Driver Qualification files, DOT safety ratings, drug and alcohol testing documentation, and insurance verification.
❱ Establish a routine for periodic verification of affiliate partners’ compliance status.
These are the same practices that protect operators from FMCSA audit exposure, satisfy modern corporate account compliance requirements, and increasingly factor into insurance underwriting outcomes.
Looking Forward
Insurance carriers will incorporate the evolving transportation liability landscape into pricing over the coming years. Corporate accounts and sophisticated clients are likely to request compliance documentation as part of vendor selection more frequently. Operators who maintain strong compliance documentation will be positioned advantageously as both affiliate partners and direct service providers.
The affiliate model that has served this industry for decades remains viable. Strengthening the documentation that supports it is a practical investment in operator resilience. [CD0626]
