WHAT THIS TOOL IS, AND WHAT IT ISN'T

CoopCheck is a public-interest search engine for FMCSA carrier data with an AI-derived Chameleon Score layered on top. We want to be plain about what that means for how you use it.

Things CoopCheck is:

• A public surfacing of FMCSA registration, crash, inspection, and violation data
• A pattern-detection layer that highlights reincorporation signals invisible to standard lookups
• A starting point for due diligence, investigation, and reporting

Things CoopCheck is not:

• Legal advice or a legal determination of any kind
• A formal FMCSA safety rating or enforcement action
• A consumer report under the Fair Credit Reporting Act (FCRA) — we are not a licensed consumer reporting agency
• The sole basis for any hiring, contracting, or compliance decision — pair it with a direct FMCSA lookup and your own due diligence

WHERE EVERY DATA POINT COMES FROM

We source directly from FMCSA public data and show you exactly where every data point comes from. There are four sources behind everything you see on this site:

• FMCSA CENSUS1 — the federal registry of every active and inactive motor carrier. Refreshed monthly. Used for carrier name, DBA, address, phone, DOT number, fleet size, operational status.
• FMCSA SMS (Safety Measurement System) input files — crash, inspection, and violation records. Sourced from data.transportation.gov. Refreshed monthly.
• FMCSA SAFER live API — used for real-time lookups when a carrier isn't yet in our monthly snapshot.
• FMCSA Query Central (QC) API — used for current authorization and operational-status checks.

CoopCheck is not affiliated with, endorsed by, or operated by the FMCSA or any government agency. We surface public data faster, in a different shape — that's it.

A Chameleon cluster match indicates a shared-contact pattern across FMCSA registrations; it does not, on its own, prove fraudulent activity. Risk labels (CRITICAL / HIGH / MEDIUM) and letter grades (A–F) are CoopCheck designations, not FMCSA designations. Carriers in CRITICAL clusters carry a minimum grade of D, and HIGH/MEDIUM clusters carry a minimum grade of B — because chameleon operators deliberately avoid accumulating violations before re-registering, a clean individual record is part of the pattern, not evidence of safety.

HOW TO CORRECT YOUR RECORD

If you're a carrier and you believe your CoopCheck listing is wrong, the data upstream is almost always wrong too — and the fix has to start there. Here's the path:

• Step 1. Find the error at safer.fmcsa.dot.gov — confirm the FMCSA SAFER record matches what we're showing.
• Step 2. Submit a correction directly to FMCSA via DataQs. This is the only system that can actually change the underlying federal record.
• Step 3. Once FMCSA accepts the correction, CoopCheck reflects it on the next monthly refresh.
• Step 4. Optionally, let us know via the Contact page so we can prioritize a re-score in the interim.

What we will not do, ever, is take money to change your score. The data is what the data is.

WHAT WE'RE NOT LIABLE FOR

We're a public-interest tool built on public data. We do the work to surface it accurately and we keep our methodology open. We can't promise a specific business outcome from using CoopCheck, and we're not on the hook for one. Specifically, CoopCheck and its operators are not liable for damages arising from:

• Business decisions made based on carrier risk scores or cluster data
• Inaccurate or outdated information in the underlying FMCSA data
• False positives or false negatives in chameleon detection
• Carrier relationships entered into or avoided based on what you read here

Use CoopCheck the way you'd use any public-records tool: as one input among several, not as the only input.

UPDATES TO THESE TERMS

We may update these terms as the product changes. Continued use of CoopCheck after an update means you've accepted the revised terms. The date at the top of this page reflects the most recent update — and our principles (public, unpayable, open to all) are not on the table.

OUR COMMITMENTS

• Open to everyone, no account required. Anyone can search this site without an account, a payment, or a login.
• No paywall on data. Every score, cluster, and source we show is visible without a subscription.
• Public sources, fully cited. Every data point links back to its FMCSA source so you can verify it.
• No pay-to-score. No carrier, broker, or enterprise can pay us to change a score. Not directly, not through a partner, not at any price.
• A correction path that actually works. If your FMCSA record is wrong, we'll show you the federal channel that can fix it — and reflect the correction once it's official.
