Supreme Court ruling turns safety records into broker liability shield
A unanimous US Supreme Court ruling has transformed safety compliance from a regulatory checkbox into a legal necessity for freight carriers. In Montgomery v. Caribe Transport II, LLC, the court ruled that brokers can now face state-level negligent hiring claims if they fail to properly vet carriers, placing the onus on carriers to prove their safety records are robust, documented, and defensible.
For nearly three decades, courts interpreted the Federal Aviation Administration Act (FAAAA) to shield brokers from state-law liability claims related to carrier selection. That protection evaporated in May when the Supreme Court closed the loophole, ruling that brokers who know, or should have known, about a carrier’s safety issues can no longer treat the matter as someone else’s problem. While the decision does not impose strict liability on brokers, it fundamentally alters the legal landscape by making a broker’s due diligence process subject to scrutiny after an accident.
This shift has immediate consequences for carriers. A clean FMCSA safety rating or active insurance policy may no longer be enough to satisfy brokers. Instead, carriers must demonstrate an ongoing, proactive safety management program, one that goes beyond baseline compliance to document risk identification, coaching, and corrective actions. Two carriers with identical FMCSA scores could now represent vastly different levels of risk, depending on how well they can prove their safety practices.
Why the ruling changes everything for carriers: Supreme Court
Montgomery adds another layer of exposure, pushing brokers to demand more than just compliance from carriers.
Not all safety programs are created equal. Fleets that have successfully navigated this new landscape tend to share a few key practices. First, they build in an adjustment period before formal coaching begins, ensuring that early reviews reflect real driving patterns rather than first-week unfamiliarity with new systems.
Second, they pair event reviews with consistent, documented coaching conversations, creating a paper trail that can be presented in court if needed. Finally, they unify compliance data and safety performance metrics, treating them as two sides of the same coin rather than separate silos.
What a defensible safety program looks like
The company’s upcoming webinar on Oct. 27 at 10 a.m. PST will focus on how fleets can transform existing safety initiatives into demonstrable, defensible records. Aimed at carrier safety, risk, compliance, and legal leaders, the session will cover practical steps for aligning safety programs with the new legal realities.
For carriers, the message is clear: compliance is no longer enough. In an industry where brokers, insurers, and courts are increasingly demanding proof of safety, not just promises, the ability to document a proactive safety culture could mean the difference between winning freight and facing litigation.
As the industry adapts, one thing is certain: the days of treating safety as a mere regulatory hurdle are over. For carriers, the new standard is simple, safety must be provable, not just compliant.
