Supreme Court Case Could Reshape Broker Carrier Selection
The Supreme Court is deciding whether freight brokers can be held liable under state negligence law for their carrier selection decisions. The case—Montgomery v. Caribe Transport II—stems from a 2017 highway collision where a severely injured plaintiff alleges C.H. Robinson negligently selected an unsafe carrier. The ruling will determine whether brokers face financial accountability for the safety quality of carriers they use, a decision with profound implications for procurement standards across the freight industry. Crucially, the article exposes a market-level failure: there is no federal standard for how brokers vet carriers. Most brokers use a satisfactory safety rating as their primary filter, yet 97% of the nation's 750,000 active carriers have never been rated. This creates a situation where brokers effectively use price, not safety, as the primary carrier selection criterion. The market incentive structure rewards cheap freight moves over safe ones, and no legal ruling alone will fix that broken incentive. For supply chain leaders, this case represents a potential tipping point. If brokers face liability, procurement departments may see stricter carrier approval processes, higher freight costs, and longer lead times as brokers reduce risk exposure. If brokers win preemption, the status quo continues—but shippers lose a regulatory lever to demand better safety standards from their logistics partners. Either way, the underlying problem persists: the freight market has commoditized safety.
A Legal Showdown Over Carrier Vetting Could Reshape Freight Procurement
On March 4, 2026, the U.S. Supreme Court heard oral arguments in Montgomery v. Caribe Transport II, a case that will determine whether freight brokers can be held liable under state law for negligently selecting unsafe motor carriers. The case traces back to a December 2017 highway collision in Illinois where a tractor-trailer veered off the road and struck a stopped vehicle, severely injuring Shawn Montgomery. He sued not only the carrier and driver but also C.H. Robinson, the freight broker that arranged the shipment, claiming negligent carrier selection. The central legal question is whether federal preemption law prevents states from imposing this liability on brokers.
For supply chain professionals, this case matters because it will determine whether procurement teams have a legal lever to demand safer carrier selection practices from their freight brokers. A decision favoring Montgomery could incentivize brokers to tighten vetting standards; a decision favoring Robinson locks in the status quo. However, the article's most damning revelation is that the legal outcome may be irrelevant to the real problem: there is no uniform federal standard for how brokers select carriers. Every broker maintains its own criteria, and most rely on a single filter that is nearly meaningless.
The Broken Vetting Standard: Why Safety Ratings Aren't Working
The primary carrier selection criterion across the industry is the FMCSA satisfactory safety rating. This sounds rigorous but is, in practice, a facade. Of the roughly 750,000 motor carriers with active operating authority in the U.S., only about 19,000 (3%) hold any FMCSA safety rating. The remaining 97% have never undergone a compliance review. When brokers say their procurement policy requires a satisfactory rating, they are effectively saying they will reject only the tiny fraction of carriers that have been audited and failed. That's not vetting—that's authority verification with a cosmetic safety filter.
Meaningful carrier vetting data exists but is routinely ignored. Brokers could scrutinize out-of-service rates by vehicle and driver, aggregate crash history (fatal, injury, and property damage counts), insurance cycling patterns that signal repeated denials and repricing, whether carrier principals have connections to revoked operations, whether physical addresses are virtual mail drops shared by dozens of shell companies, and whether carriers were formed weeks ago with zero operational history. Instead, most brokers prioritize price—the lowest rate bid wins, and safety considerations remain secondary despite being the most critical decision in American surface transportation.
Market Incentives Over Legal Accountability
The brokers' argument before the Supreme Court is revealing: they claim holding them liable for negligent hiring would force them to use only large, well-capitalized carriers. This is, implicitly, an admission that brokers currently hire carriers they would not hire if accountability were attached. It's a confession dressed as a legal defense—and it points to the real problem. The freight brokerage market has optimized for price at the expense of safety. Spot freight rates pressure brokers to prioritize low cost-per-mile, not carrier reliability or safety history.
Neither a Supreme Court ruling in Montgomery's favor nor one favoring Robinson solves this market failure. If Montgomery wins, brokers face state negligence liability but only after an incident occurs—lawsuits filed three years after a crash do nothing to change the rate email sent out last Tuesday seeking the cheapest truck from Norfolk to Detroit. If Robinson wins, brokers face no liability and have no incentive to change procurement practices at all. What the market needs is regulatory mandate: the FMCSA could require all brokers to maintain documented carrier selection criteria, apply them consistently, and demonstrate that those criteria encompass crash history, violation patterns, and insurance quality—not just safety rating status. The agency has chosen not to act.
Supply chain leaders should recognize that their freight procurement decisions are operating within a structurally broken system. Shippers bear the risk when a broker's cost-optimization calculus results in an unsafe carrier selection and an incident occurs. Demanding deeper carrier vetting from brokers is not a nice-to-have; it's a necessity. Whether the Supreme Court imposes legal liability or not, procurement departments should unilaterally adopt more rigorous carrier evaluation processes and include crash history, out-of-service data, and insurance patterns in their carrier approval matrix. The motoring public—and your company's supply chain reputation—cannot wait for the law to catch up.
Frequently Asked Questions
What This Means for Your Supply Chain
What if brokers are held liable and tighten carrier approval requirements?
Simulate the impact of brokers reducing their approved carrier networks by 30%, selecting only carriers with documented safety records and no recent violations. Model increased procurement costs (5-15%), longer transit times due to reduced carrier availability, and reduced load flexibility.
Run this scenarioWhat if FMCSA mandates documented carrier vetting standards?
Simulate FMCSA requiring all brokers to document and report carrier selection criteria, including crash history, out-of-service rates, and insurance patterns. Model the compliance cost, process overhead, and potential improvement in network-wide carrier safety. Assess whether this reduces procurement flexibility while improving risk profile.
Run this scenarioWhat if brokers win preemption and nothing changes operationally?
Simulate continuation of current loose carrier vetting standards. Model sustained price pressure on freight rates, no improvement in carrier safety metrics, and sustained risk of incidents involving poor-quality carriers. Assess the long-term liability exposure for shippers who knowingly use brokers with weak vetting.
