SCOTUS Ruling: Why Brokers Are Now Checking Your CSA Scores Before Every Load

On May 14, 2026, the U.S. Supreme Court handed down a unanimous 9-0 decision in Montgomery v. Caribe Transport II, LLC that every owner-operator and hotshot carrier running under their own authority needs to understand — because it directly affects your ability to get loads.

This wasn't a case about drivers. It was about a freight broker. But the ripple effect lands squarely on you.

What Happened in Montgomery v. Caribe Transport?

In 2017, truck driver Shawn Montgomery lost part of his leg when a tractor-trailer operated by Caribe Transport struck his parked vehicle on Interstate 70 in Illinois. The load had been arranged by C.H. Robinson — one of the largest freight brokers in the country.

Montgomery sued C.H. Robinson, arguing the broker should have known Caribe Transport was an unsafe carrier. At the time of the dispatch, Caribe had a "Conditional" FMCSA safety rating and documented deficiencies in driver qualification, hours of service compliance, vehicle maintenance, and crash history — all publicly available data.

C.H. Robinson's defense was that federal law — specifically the Federal Aviation Administration Authorization Act (FAAAA) — shielded them from state negligent-hiring lawsuits. Courts had been split on this for years.

The Supreme Court settled it. All nine justices agreed: the FAAAA's safety exception preserves states' authority to hold brokers accountable for negligently hiring unsafe carriers. The federal preemption shield is gone.

Why This Matters for Owner-Operators

You might be thinking: "That's a broker problem, not mine." Not exactly.

The carrier in this case — Caribe Transport — had a Conditional safety rating and red flags in their CSA scores. That's the profile brokers are now legally motivated to avoid booking. Every broker who has read this opinion is updating their vetting process right now.

Here's what that means practically:

Brokers are going to be checking your FMCSA data more carefully than ever before. Not just whether you have active authority — but your safety rating, your CSA BASIC percentile scores, your out-of-service rates, your authority age, and whether your driver qualification file looks solid.

Carriers who look like Caribe Transport on paper are going to find it harder to get loads. Carriers with clean records are going to become more valuable.

What Brokers Will Be Looking At

Based on how the ruling frames carrier vetting liability, here's the data brokers will scrutinize before booking you:

Your FMCSA Safety Rating

There are three possible ratings: Satisfactory, Conditional, and Unsatisfactory. A Conditional rating — the one Caribe Transport held — signals to brokers that your safety management controls are inadequate. After Montgomery, booking a Conditional-rated carrier creates documented liability exposure. Expect many brokers to stop doing it.

Your CSA BASIC Scores

The FMCSA Safety Measurement System tracks seven BASIC categories. The intervention thresholds brokers will flag:

One elevated BASIC is a yellow flag. Multiple elevated BASICs is the profile that gets you declined.

Your Authority Age

Carriers with authority under 18 months are already under heightened scrutiny in new entrant audits. Post-Montgomery, brokers will treat new authority as an additional risk factor, especially without a clean track record to offset it.

Your Driver Qualification File

Caribe Transport's driver qualification deficiencies were specifically cited in the case. Brokers reviewing your profile will expect that your DQ file — CDL, medical certificate, MVR, employment history, drug testing enrollment — is current and complete.

What You Should Do This Week

Step 1 — Pull your safety rating

Go to safer.fmcsa.dot.gov and search your DOT number. If your rating is Conditional, begin the corrective action process immediately. A Conditional rating is the single most damaging thing a broker can see in your profile right now.

Step 2 — Check your CSA BASIC scores

Log into ai.fmcsa.dot.gov/SMS. Look at each BASIC category. If any score is approaching or above the intervention threshold, identify the specific violations driving it — most Vehicle Maintenance scores, for example, trace directly to brake, lighting, and tire issues found during roadside inspections that a consistent pre-trip inspection program can reduce.

Step 3 — Get your documents organized

Brokers aren't just checking your FMCSA data. If you're asked to document your compliance in an onboarding process, you need to produce your CDL, medical certificate, annual inspection report, insurance certificate, and registration quickly and cleanly. A binder full of crumpled papers from the cab isn't going to cut it with brokers who are now documenting their vetting decisions.

Step 4 — Dispute inaccurate violations

If you have violations in the DataQ system that are wrong, inaccurate, or should have been dismissed, file a DataQ challenge at dataqs.fmcsa.dot.gov. Removing inaccurate violations is one of the fastest ways to improve an elevated BASIC score.

The Flip Side: Clean Carriers Win

It's not all bad news. The same ruling that creates problems for carriers with red flags creates opportunity for carriers with clean records.

Brokers need defensible carriers. A carrier they can point to — good safety rating, CSA scores below thresholds, clean inspection history, organized documentation — is a carrier they can defend booking if something goes wrong down the road. In a post-Montgomery market, being a demonstrably safe carrier isn't just the right thing to do. It's a competitive advantage.
