Montgomery v. Caribe Transport Unanimous Verdict: Freight Broker Liability Playbook

The unanimous Supreme Court ruling in Montgomery v. Caribe Transport II, LLC turns carrier selection into a board-level risk for freight brokers. The decision does not make every broker liable for a carrier crash, but it removes the clean federal preemption defense many brokers expected to use against state-law negligent-selection claims.

Direct Answer / TL;DR

On May 14, 2026, the Supreme Court unanimously held that FAAAA preemption does not block state-law negligent-selection claims against freight brokers when the claim concerns motor vehicle safety (Cornell LII, AP News). Brokers should treat carrier vetting, FMCSA safety review, documentation, and tender approval notes as litigation-critical workflows, not back-office cleanup.

Key Takeaways for Freight Brokers

• The Supreme Court ruling was unanimous, with Justice Barrett writing for the Court and Justice Kavanaugh joined by Justice Alito in concurrence.
• State-law negligent-selection claims against brokers can move forward when they concern unsafe motor carriers or drivers.
• The ruling does not decide whether C.H. Robinson was negligent or whether brokers will routinely lose crash lawsuits.
• Brokers now need stronger proof that they used reasonable care when selecting carriers for each load.
• FMCSA authority, insurance, safety rating, crash history, and documentation gaps should be reviewed before tendering freight.
• ARK TMS is designed for small teams (1-25 users) that need fast carrier onboarding, compliance visibility, and low overhead without enterprise complexity.

What Changed

The Supreme Court reversed the Seventh Circuit and held that negligent-selection claims against freight brokers fall within the FAAAA safety exception when they concern motor vehicle safety. The Court concluded that a claim alleging a broker negligently selected an unsafe carrier is not barred simply because the defendant is a broker rather than a motor carrier.

The Verdict Was Unanimous

Justice Amy Coney Barrett delivered the opinion for a unanimous Court. That matters because broker liability is no longer a narrow circuit-split issue; the country now has one controlling federal answer on whether FAAAA preemption categorically blocks this type of state tort claim.

Before the ruling, brokers pointed to decisions from the Seventh and Eleventh Circuits that favored preemption, while plaintiffs pointed to Sixth and Ninth Circuit decisions allowing negligent-selection claims to proceed. The Supreme Court resolved that split against categorical broker preemption.

What the Court Actually Held

The Court held that a claim alleging one company negligently hired another to transport goods is saved by the FAAAA safety exception because it concerns motor vehicles. In practical terms, a plaintiff injured in a truck crash may be able to pursue a state-law negligent-selection claim against the broker that arranged the carrier.

That is not the same as automatic broker liability. The case returns for further proceedings, and plaintiffs still must prove negligence, causation, damages, and any state-law elements that apply.

What the Court Did Not Decide

The ruling does not create a federal carrier-vetting checklist. It also does not say brokers are insurers of every carrier they hire or that a broker is liable whenever a carrier causes a crash.

Justice Kavanaugh’s concurrence specifically warned that litigation and insurance costs may rise, but also noted that brokers should be able to defend claims when they act reasonably and arrange transportation with reputable carriers. For brokers, the operational takeaway is clear: the defensible process matters as much as the final carrier choice.

Why It Matters to Brokers

The unanimous verdict raises the value of documented carrier selection because the central question in future claims will often be whether the broker acted reasonably before tendering the load. A broker that cannot show what it reviewed, who approved the carrier, and why the carrier was considered acceptable will be in a weaker position after a crash.

Carrier Vetting Is Now Litigation Evidence

Carrier onboarding and load tendering records may become evidence in negligent-selection lawsuits. Brokers should expect plaintiff attorneys to ask what safety signals were available, whether the carrier had an FMCSA safety rating, whether insurance was current, whether authority was active, and whether known red flags were ignored.

Small brokerages are especially exposed because carrier checks often live across spreadsheets, email threads, load-board notes, and individual rep judgment. That fragmentation makes it harder to reconstruct a reasonable selection process months or years later.

Capacity Strategy May Change

The decision may push some brokers toward larger carriers that can provide cleaner safety documentation, stronger insurance records, and more formal compliance procedures. That could make capacity thinner for small carriers in certain shipper networks, especially where customers or insurers demand tighter vetting standards.

The risk is not only legal. If brokers respond by narrowing carrier pools too aggressively, spot coverage can get slower and buy rates can rise on lanes where reliable small carriers are the main source of capacity.

Insurance and Contracting Will Get More Attention

Broker liability insurance, shipper contracts, broker-carrier agreements, indemnity language, and customer safety requirements will receive more scrutiny after the ruling. Brokers should coordinate with counsel and insurance advisors, but operations teams still need a daily workflow that produces clean records before legal review becomes necessary.

Craig Fuller Warned the Broker Impact Could Be Severe

FreightWaves founder Craig Fuller had already flagged the downside risk for brokers before the decision; a public clip from a conversation with Fuller was framed as a potential "catastrophe for freight brokers" if the Court allowed broker liability claims to proceed (r/FreightBrokers). That warning is now operationally relevant because the unanimous decision lets plaintiffs test broker carrier-selection decisions in state-law negligence claims instead of ending those claims at federal preemption.

The practical concern is not that every broker becomes automatically liable. The severe risk is that brokers without a documented vetting process may face higher defense costs, tougher insurance questions, and more pressure from shippers to prove how each carrier was selected.

What Brokers Should Do Now

Brokers should update carrier selection procedures immediately because the ruling changes the litigation posture for interstate freight arranged by brokers. The goal is not to eliminate every risk; the goal is to make reasonable carrier selection visible, repeatable, and provable.

1. Define a Minimum Carrier Approval Standard

Create a written carrier approval policy that covers active FMCSA authority, insurance status, safety rating, out-of-service signals, crash history review, identity verification, and documentation expiration. Apply the standard consistently so every rep is using the same baseline.

For higher-risk freight, add stronger checks. High-value cargo, hazmat, time-critical freight, cross-border moves, and unfamiliar carriers should require additional review before dispatch.

2. Capture the Reason for Carrier Selection

Do not rely only on a carrier being available at the right price. Record why the carrier was accepted for the load, including prior performance, lane experience, compliance status, insurance confirmation, and any customer-specific requirements.

This does not need to become a long memo for every shipment. A short, structured approval trail is usually more useful than scattered notes that no one can search later.

3. Create a Red-Flag Escalation Path

Define what requires manager review before tendering. Common escalation triggers include conditional or unsatisfactory safety signals, recent authority changes, insurance changes, mismatched contact details, questionable addresses, unresolved claims, poor inspection history, and identity concerns tied to freight fraud.

Escalation should produce a yes-or-no decision and a record of who approved it. Silence should not function as approval.

4. Refresh Carrier Records on a Schedule

Carrier approval is not a one-time event. Brokers should refresh key records before tendering to carriers that have been inactive, changed ownership, changed insurance, changed authority status, or appeared in a fraud or compliance review.

At minimum, small brokerages should track expiration dates for insurance, authority review, carrier packets, safety checks, and customer-specific documents. Manual reminders are easy to miss when the market gets tight.

5. Align Sales Promises With Compliance Reality

Sales teams should avoid promising instant coverage with unfamiliar capacity unless operations can complete vetting before pickup. After Montgomery, speed still matters, but undocumented shortcuts create legal and customer risk.

Brokerages should set shipper expectations that certain lanes or high-risk freight may require more lead time for carrier verification. That is easier to explain before a service failure or claim.

Tactical Checklist for Freight Broker Teams

Use this checklist to convert the ruling into an operational workflow.

• Confirm active FMCSA authority before tendering a new carrier.
• Verify insurance directly through reliable documentation and track expiration dates.
• Review safety rating, inspection history, crash history, and out-of-service indicators.
• Flag conditional, inactive, newly changed, or inconsistent carrier records for escalation.
• Match carrier identity across DOT number, legal name, DBA, address, phone, email, and remittance details.
• Keep broker-carrier agreements and carrier packets tied to the carrier profile.
• Record customer-specific carrier requirements on the load before dispatch.
• Store the approval trail with the load, not only in email or chat.
• Re-vet carriers after ownership, authority, insurance, contact, or fraud-risk changes.
• Review insurance and contract language with counsel after the Supreme Court decision.

Manual Workflows vs Modern TMS

Who This Matters For

This is relevant if you:

• Run a freight brokerage with 1-50 employees
• Arrange interstate truckload freight
• Use small carriers or spot-market capacity
• Manage carrier onboarding in spreadsheets, email, or shared folders
• Need to prove how carriers were approved for specific loads

You can safely ignore this if you:

• Are an asset-based carrier with no brokerage operations
• Do not arrange motor carrier transportation
• Already have enterprise-grade carrier compliance automation and legal review on every exception

How Modern Brokerages Handle This

Modern brokerages centralize carrier onboarding, documents, compliance checks, and load-level approval notes in a single TMS so carrier selection can be reviewed quickly and consistently. Systems like ARK TMS are built for small teams (1-25 users) that need speed, compliance visibility, and low overhead without enterprise ERP complexity, asset-fleet management, or custom development projects.

The point is not to turn freight brokers into law firms. The point is to make reasonable carrier selection part of the operating system: visible before pickup, searchable after delivery, and defensible if a claim appears years later.

What This Means Going Forward

The unanimous Montgomery verdict makes broker liability a workflow problem as much as a legal problem. Brokerages that keep treating carrier vetting as informal tribal knowledge will face more risk than teams that standardize approvals, document exceptions, and keep compliance records attached to each load.

The Supreme Court left room for brokers to defend reasonable decisions. That room is most valuable when the brokerage can show exactly what it knew, what it checked, and why the carrier was selected.
