The public deserves to know
who is on the road.

Dangerous carriers dissolve after crashes and violations, reopen under new names, and get back on the road with a clean record. CoopCheck's AI cross-references 2.06M+ FMCSA carriers to surface them — instantly and publicly.

APR 2026National Spotlight

Chameleon carriers made national headlines in April 2026.
They've been on our radar since day one.

A chameleon carrier is a trucking company that accumulates safety violations, dissolves to escape enforcement, and reincorporates under a new registration. A clean record on paper.

The federal data to spot them is public. The patterns are not. They span millions of records across years of registrations, and standard FMCSA lookups can't see any of it.

Why CoopCheck Exists

FMCSA data is public.
The patterns are not.

Carriers with histories of fatal crashes, unpaid fines, and federal violations dissolve. They register new DOT numbers, new company names, new insurance. On paper they look clean. On the road — Same trucks. Same drivers. Same operators. Same danger. Different name.

The data to connect them exists. It lives inside millions of FMCSA records spanning years of registrations, shared phone numbers, common addresses, and overlapping ownership. Standard lookups can't see any of it.

CoopCheck's AI ingests the entire FMCSA dataset every month, normalizes it, and maps carrier networks across shared identifiers to produce a Chameleon Score anyone can read in seconds.

The federal data belongs to the public.

Now the analysis does too.

How It Works

Today's record.
Yesterday's company.

The Problem

The history is hidden by design.

GAO data found chameleon carriers are roughly 3x more likely to be involved in serious crashes than compliant carriers. Most carrier lookup tools show you today's record — not the history behind a new registration.

The Solution

AI sees what manual lookups can't.

CoopCheck's AI maps carrier networks across shared addresses, phone numbers, and registration histories across 2.06M+ FMCSA carriers to detect reincarnation patterns invisible to standard lookups.

The Benefit

Before you book, write, or publish — you know.

Before you book a load, write a policy, or publish a story — you know. Not just whether a carrier is currently compliant, but whether they've been here before under a different name.

How the AI Works

The patterns are buried
in volume, not complexity.

FMCSA's CENSUS1 and SMS data is public, but it's also raw, inconsistent, and enormous. Three things have to happen before a Chameleon Score makes sense.

Clean the data.

FMCSA exports are raw — duplicate spellings, missing fields, stale entries. The AI normalizes the entire dataset every month so every carrier is comparable.

Cross-reference at scale.

A shared phone here, a reused address there, a registration cluster three years apart. The patterns that reveal chameleon carriers span millions of records — invisible to manual lookup, obvious to the model.

Score transparently.

The Chameleon Score combines shared identifiers, registration patterns, and violation history into a 0-100 number, with the math published openly.

AI matters here because the evidence is buried in volume, not complexity.

Who Uses CoopCheck

Built for the people
checking the work.

CoopCheck is open to brokers, shippers, insurers, journalists, law enforcement, researchers, and carriers themselves.

Anyone can search. No one can pay to change their score.

If you believe your FMCSA data contains an error, you can flag it and we'll show you how to correct it at the source. What you cannot do is pay to alter your Chameleon Score. The data is what the data is.
