Most freight brokers look up a carrier before they book it. They check the authority, glance at the safety rating, maybe eyeball the insurance, then dispatch the load and move on. That’s diligence. But if something goes sideways months later and ends up in court, can they prove any of it happened? For most brokers, no. And after a Supreme Court ruling this spring, that gap is the whole ballgame.
That’s what LongMile says it’s built to close. According to the company, every time a broker looks up a carrier, the platform produces a timestamped due-diligence report automatically, a record of what got verified and when. The pitch is no more opening a dozen tabs, screenshotting a SAFER page, and hoping you saved enough. The company says you get a structured report in seconds covering authority status, insurance and bond validation, safety history, crash and out-of-service signals, and chameleon-carrier cross-referencing, each one logged with a timestamp showing when the source was checked.
“The uncomfortable truth after Montgomery is that undocumented diligence is legally invisible,” said Sam Nazirov, founder of the carrier-intelligence platform LongMile. “Most brokers do look carriers up. Very few can produce a timestamped record proving what they saw and when they saw it. That gap is now the difference between a defensible file and a settlement.”
The Montgomery he’s talking about is Montgomery v. Caribe Transport II, LLC, which the Supreme Court decided 9-0 on May 14, 2026. Justice Amy Coney Barrett wrote the opinion, holding that state-law negligent-hiring claims against freight brokers aren’t preempted by the Federal Aviation Administration Authorization Act. Translation: brokers used to get carrier-selection lawsuits thrown out early on federal preemption grounds. That defense is gone. These cases can reach a jury now, and the jury decides whether the broker used ordinary care and whether it knew, or should have known, about safety red flags sitting in public FMCSA data at the time of dispatch.
It’s a question about evidence, which is exactly where LongMile’s pitch lives. A broker who checked everything but kept no record can end up in the same spot before a jury as a broker who checked nothing. The company’s fix is making the record build itself. According to LongMile, it reduces each carrier to a single 100-point score, with safety weighted at 55 points, authority at 25, and identity at 20, and lets you tap any component to see the math behind it against the national average. Save a carrier you already work with and, per the company, you’ll get alerts when its authority changes, insurance lapses, or safety scores cross a threshold, so trouble shows up before the next load instead of after a claim.
The chameleon-carrier piece is where LongMile says it goes past the free federal tools. FMCSA’s public database gets searched one identity at a time, by DOT or MC number or company name. It won’t flag that an operator shut down a troubled authority and quietly re-registered under a clean one, the exact move regulators call a chameleon carrier. LongMile says it cross-references shared phones, emails, officers, and addresses to catch that reuse before you book, not after.
What jurors will ask now is simple. Did you check, did you review the signals, and can you prove it? Diligence you can’t document is diligence you can’t defend, and that’s the case LongMile is making. See how it works at longmile.io or through the company’s LinkedIn.
