What Retailers Need to Know About the U.S. Supreme Court’s Montgomery v. Caribe Transport Decision

The U.S. Supreme Court’s recent ruling in Montgomery v. Caribe Transport II, LLC will significantly reshape risk management across the retail logistics industry. 

In a unanimous 9-0 decision issued on May 14, 2026, the Court ruled that freight brokers can be sued under state negligence laws for hiring unsafe motor carriers. The decision removes a long-standing federal preemption defense that brokers and logistics intermediaries had relied on for years under the Federal Aviation Administration Authorization Act (FAAAA). 

For retailers—and shippers of any industry—that leverage third-party logistics providers (3PLs) and freight brokers, the ruling sends a clear message: carrier selection practices are now under much greater legal scrutiny.

Background

The case stemmed from a 2017 highway accident where the injured driver argued that the freight broker negligently selected a carrier with known safety issues. Lower courts, including the Seventh Circuit, initially dismissed the claim citing federal preemption under the FAAAA.  A similar case in the Sixth Circuit came to the opposite conclusion, and the Supreme Court decided to hear Montgomery to resolve the split and decide the issue.

Why Retailers Should Pay Attention

While the decision directly affects freight brokers, retailers and other shippers are unlikely to be insulated from the broader operational consequences.

Many retailers work with broker and 3PL partners to execute transportation plans, with the explicit expectation that those partners are properly vetting carriers. Following this ruling, in the event of an incident, plaintiffs’ attorneys will likely examine the entire supply chain— including shipper oversight practices, contracting standards, and carrier qualification requirements. Industry analysts already expect a sharp rise in litigation targeting transportation intermediaries.

The ruling also increases the industry’s focus on safety metrics alongside cost and capacity. Consequently, Federal Motor Carrier Safety Administration (FMCSA) metrics will come under increased scrutiny as a significant component of industry safety reviews.  This is a timely topic as freight fraud, chameleon carriers, and FMCSA registration have been very much in the spotlight due to skyrocketing cargo theft.

What Retailers Should Consider

Retailer shippers should review transportation procurement practices now, particularly if they rely at all on 3PLs, freight brokers, or spot-market freight. Key areas to evaluate include:

• Carrier vetting and onboarding procedures
• Safety score monitoring and documentation
• Insurance verification standards
• Written broker compliance requirements
• Audit trails showing due diligence in carrier selection, including FMCSA ratings
• Transportation contract language regarding carrier hiring and vetting
• Dock and driver/carrier check-in procedures

Some logistics service provider partners are already emphasizing enhanced carrier screening, including FMCSA safety reviews, active authority checks, and ongoing monitoring programs. 

Broader Industry Impact

The broader impact of the decision is still becoming clear, but it is certain to affect the industry’s practices.

As smaller carriers with fewer resources and inconsistent ratings may find it harder to secure loads, and brokers may become more selective in their carrier networks, this may ultimately accelerate consolidation within the freight market.

At the same time, the ruling reinforces a broader trend in supply chain management: legal accountability increasingly follows operational decision-making. Choosing transportation partners is no longer viewed solely as a procurement function—it is now a material risk-management issue.

For retailers navigating tight delivery windows and ongoing transportation volatility, the takeaway is straightforward: ongoing transparency and close engagement with logistics service provider partners is essential.
