The Supreme Court Broker Liability Ruling: Why Compliance Is the New Capacity

Two headlines collided in freight this month. The Supreme Court stripped brokers of a legal shield they had leaned on for forty years, and truckload spot rates hit an all time high. Most coverage treated those as separate stories. They are not. The ruling is quietly becoming a capacity event, and capacity events become rate events. Here is how the two connect, and what it means if you ship freight, haul it, or broker it.

What the Supreme Court actually decided

On May 14, 2026, in a unanimous 9 to 0 decision, the Supreme Court ruled in Montgomery v. Caribe Transport II that the Federal Aviation Administration Authorization Act does not shield freight brokers from state law negligence claims when they select an unsafe carrier. Justice Amy Coney Barrett wrote the opinion. Justice Brett Kavanaugh filed a concurrence joined by Justice Samuel Alito.

For decades, brokers used the FAAAA as a near automatic off ramp. Because the law preempts state rules that relate to a broker\'s prices, routes, or services, brokers argued that negligent selection claims were preempted and got many cases dismissed before they ever reached a jury. The Court held that these claims fall under the law\'s safety exception, the carve out that preserves state authority over motor vehicle safety. The shield is gone.

The case itself is the kind of fact pattern that keeps brokers up at night. In 2017, a truck operated by Caribe Transport veered off an Illinois highway and the plaintiff, Shawn Montgomery, lost his leg. At the time, Caribe held a conditional safety rating with documented problems in driver qualifications, hours of service, maintenance, and crash history. The question the Court answered was simple: can a broker be taken to court for putting that load on that carrier? The answer is now yes.

Why brokers are tightening the screws right now

You can already see the response moving through the market. C.H. Robinson, the largest broker in the country and the defendant in the case, has formally raised its bar. It lifted its minimum carrier liability insurance requirement from the federally mandated $750,000 to $1 million, stopped working with carriers that hold a conditional safety rating, added a seven day waiting period before it will use a newly authorized carrier, and cut carriers its internal model flags as high risk.

Robinson says the affected carriers represent less than one percent of its annual North American truckload volume, and it invited them to requalify. That framing is doing a lot of work. One percent of the nation\'s largest brokerage is still a meaningful slice of small carriers, and Robinson is the bellwether. When the biggest player in the market redraws its carrier standards, everyone downstream feels pressure to match it, because nobody wants to be the broker that used the carrier Robinson would not touch.

The part nobody is connecting: this is a capacity story

Here is the piece that turns a legal ruling into a freight market story. The new vetting discipline is colliding head on with a market that already has nothing to spare.

Roughly 1.2 million trucks, about 36 percent of the fleet, carry no FMCSA safety rating at all, and another 300,000 or so hold a conditional rating. That is close to 1.5 million trucks that a careful broker now has to think twice about. Schneider National has noted that only around 50,000 carriers clearly meet strict safety vetting standards, far below the 100,000 plus rosters brokers used to run. Take supply that was already short and tell the market that a large chunk of it is now a liability question, and you get exactly what we are seeing: spot rates at records, tender rejections near 18 percent, and contract routing guides falling apart.

That last point is the tell. Truckload contract rates set in early 2026 bid season are breaking down because contracted carriers are rejecting loads and shippers are getting pushed onto a far more expensive spot market. J.B. Hunt has signaled it is targeting a cumulative rate increase around 20 percent over two years. The era of waiting out a soft market is over. Compliance has become a supply constraint, and supply constraints are priced.

What this means for you

If you are a shipper

Expect your broker partners to get pickier about carriers, and understand that the pickiness is protecting you too. A negligent selection claim does not stop at the broker. Plaintiffs name shippers, and your contracts and insurance are now part of the risk picture. Three moves are worth making this quarter: review your transportation agreements for carrier selection standards and indemnification language, confirm that contingent auto and contingent cargo coverage is adequate on both sides, and document the safety expectations you have communicated to your brokers. The cheapest broker and the safest broker are no longer guaranteed to be the same company, and the gap between them is now a number you can be sued over.

If you are a carrier

Your CSA scores and safety profile just became a business asset, not a back office detail. Brokers will pull your FMCSA SAFER record, your inspection history, your out of service rate, your authority age, and your crash history before they offer you a load, and increasingly they will keep that record on file. A conditional rating or a thin inspection history is now a reason to be passed over, even in a tight market where you would otherwise have leverage. The flip side is real opportunity: clean carriers are scarcer than the loads chasing them, and a strong safety record is turning into pricing power.

If you work with a broker

Ask how they vet. A broker that can walk you through exactly what they check, how often, and how they document it is a broker that can defend the loads they put under your freight. A broker that cannot is exposure you are quietly carrying.

How AFX approaches carrier vetting

We did not wait for a Supreme Court ruling to take carrier vetting seriously. Before a carrier hauls a load in the AFX network, we verify active FMCSA operating authority and current insurance, review their safety profile, and document what we checked. Conditional ratings, weak inspection history, and brand-new authority are red flags we weigh, not rounding errors we ignore. The point is not a marketing line. It is that when a shipper asks how we chose the carrier on their freight, we have a real answer, in writing.

The bottom line

The Montgomery decision did not just change the legal exposure of one company. It changed the math of the whole market. Vetting is now both a legal obligation and a capacity filter, and the two reinforce each other: the safer everyone gets, the tighter capacity becomes, and the more rates climb. For shippers, the takeaway is to choose a broker on the strength of its process, not just its price. For carriers, it is to treat your safety record like the revenue driver it has become. And for everyone, it is to stop thinking of compliance as paperwork. In 2026, compliance is capacity.
