BREAKING — The U.S. Supreme Court ruled 9-0 today in Montgomery v. Caribe Transport II, LLC that state negligent-hiring claims against freight brokers are not preempted by the Federal Aviation Administration Authorization Act. Justice Amy Coney Barrett wrote the majority opinion. Justice Brett Kavanaugh, joined by Justice Samuel Alito, filed a concurrence. The ruling collapses the FAAAA preemption shield that the freight brokerage industry has leaned on for the past five years and clears the path for state tort suits in every jurisdiction where a broker arranges transportation, per FreightWaves’ breaking coverage of the decision.
Independent carriers, dispatchers, and small fleet owners need to read this ruling carefully. The Court did not just decide one truck-crash case. It rewrote the broker-carrier risk equation overnight — and the carriers who are going to feel the aftershock first and hardest are the small operators who depend on a broker market that is about to retract sharply on the carrier-vetting side.
What the Court Decided Today
The narrow legal question was whether 49 U.S.C. § 14501(c)(2)(A) — the FAAAA’s “safety regulatory authority” exception — saves a state-law negligent-hiring claim against a freight broker from the statute’s broader preemption rule. Justice Barrett’s opinion concluded that it does. Requiring a broker to exercise ordinary care in selecting a carrier “concerns motor vehicles” — most obviously, the trucks that will transport the goods — and therefore falls within the safety exception and is saved from preemption, per Transport Topics’ coverage of the opinion.
The plain-English version: a freight broker who hires an unsafe carrier and causes a crash can be sued under state tort law in the state where the crash happened. The federal preemption defense that brokers have raised at the motion-to-dismiss stage since 2023 is gone. Every broker in the United States is now subject to state-court negligence claims for the carriers they choose to hire, per Bloomberg Law’s analysis of the ruling.
How the Case Got Here
The Court’s decision arose out of a 2017 Illinois crash. Shawn Montgomery was struck by a tractor-trailer operated by Caribe Transport II, LLC, an interstate motor carrier whose load had been brokered by C.H. Robinson. Montgomery’s injuries required partial amputation of his leg. He sued the driver, the carrier, the trailer lessor, and the broker, alleging that C.H. Robinson was negligent in selecting Caribe given the carrier’s safety record. The lower courts split on whether the FAAAA preempted the broker-negligence claim. The Supreme Court took the case in late 2025 and heard oral argument on March 4, 2026, according to Commercial Carrier Journal’s reporting on the case history.
Today’s unanimous decision answers the question definitively in Montgomery’s favor on the preemption issue. The underlying negligent-hiring claim now returns to state court for trial on the merits.
“If you are a freight broker operating in the United States today, the preemption defense relied on since 2023 is gone, and brokers are now subject to state tort law in every jurisdiction where they arrange transportation.”

Why the Aftershock Hits Small Carriers Hardest
The headlines today are about brokers. But the downstream impact runs straight through the small-carrier segment, and independent operators should be reading it that way before the weekend.
Brokers are about to dramatically tighten carrier-vetting standards because every dispatch decision is now a potential state-court negligence exhibit. Expect immediate changes to the broker-carrier setup process in the next 30 to 60 days, per Trucking Dive’s reporting on the operational implications. The carriers who will pass the tighter screen are the ones with clean CSA scores under the new 2026 SMS methodology, current insurance with adequate limits, no recent out-of-service patterns, and verifiable operating history. The carriers who will struggle are exactly the ones the small-carrier segment is full of: newer authorities, owner-operators rebuilding from a bad inspection, fleets with one or two stale CSA categories, and operations that have leaned on the broker setup process being lenient.
The structural problem is bigger than vetting friction. Smaller brokers — the ones who service the long tail of small carriers — carry less insurance, have thinner legal reserves, and cannot absorb a single state-court negligent-hiring judgment the way C.H. Robinson can. Some of those smaller brokerages will exit the market in the next 12 months. The independent carriers who depended on those broker relationships for daily load flow will find themselves competing harder for fewer broker seats — precisely at the moment when broker-side underwriting just got stricter.
What Changes Inside the Broker Office Tomorrow Morning
- Carrier setup packets will get longer. Expect requests for safety policies, drug-and-alcohol program documentation, dispatcher SOPs, and updated CSA pulls before first dispatch.
- Insurance verification will move from paperwork to phone calls. Brokers will start calling the insurance agent of record before booking, not just collecting a COI.
- CSA score thresholds will be enforced more strictly. The new 2026 SMS proportionate-percentile methodology will be applied as a hard gate, not a soft preference.
- Out-of-service patterns will be re-screened. Carriers who had a violation cluster during Roadcheck week this month will see brokers re-pulling SAFER reports before Monday.
- Smaller brokers may exit lanes. Niche brokerages without the legal reserve to absorb a state-tort judgment will narrow their carrier rosters or pull out of higher-risk segments entirely.
What Independent Carriers Should Do Friday Morning
- Pull your SAFER profile at safer.fmcsa.dot.gov and verify everything is current and clean before brokers start re-pulling it Monday.
- Pull your fresh CSA scores under the new 2026 SMS methodology so you know exactly what brokers will see when they screen.
- Update your carrier setup packet with current insurance, an updated W-9, a clean MCS-150, and a brief safety policy statement — many brokers will start asking for one.
- Run a DataQs challenge on any Roadcheck-week violation that should not be on your record. The next 14 days are the easiest window.
- Diversify your broker book. If 30% or more of your monthly revenue comes from one broker, the Montgomery aftershock is a forcing function to add two or three new direct broker relationships before the vetting tightening fully lands.
- Check your liability coverage. Carriers carrying minimum-required limits may see brokers requiring higher coverage as part of the new setup process.
What Comes Next
The first wave of post-Montgomery negligent-hiring lawsuits will land within weeks. Plaintiffs’ firms that have been holding state-court complaints waiting for this ruling will start filing by Monday. Expect a 30 to 60 day stretch of broker-side risk recalibration, followed by a sharper segmentation of the broker market between the largest national players (who have the legal and insurance reserves to absorb the new exposure) and the smaller regional and lane-specific brokerages (some of whom will retreat or exit).
For independent carriers, the message is simple: the next 90 days will be the most important window of the year to get your safety paperwork right and your CSA picture clean. Brokers who used to ask for a COI and a W-9 are about to ask for a safety policy, a written hiring practice statement, and a dispatcher SOP. The carriers who have those ready will keep their broker relationships. The carriers who don’t will find their phones quieter starting Monday morning.
