Carrier red flags: the 21 risk signals we check

There is no neural net here and no black-box score out of 100. It is a rule engine, and it runs in one pass:

1. Any single critical finding forces High. The weighted rules are still listed on the profile, but they no longer change the level. One critical is enough.
2. Otherwise, the weighted findings are added up. Most weighted rules carry 2 points; the softer ones carry 1.
3. A total of 2 or more is Medium. Below 2 is Low. So one 2-point finding lands a carrier at Medium by itself, and so do two 1-point findings.

That is the entire model. It means a Medium can be triggered by a single shared phone number, and it means a carrier with two mild findings and a carrier with one serious finding land in the same bucket. Read the factors, not just the badge.

A chameleon carrier — the industry also says reincarnated carrier — is an operator who was shut down and came back wearing a new number. FMCSA revokes the authority, or an unsatisfactory rating makes the MC unusable, or the safety history gets bad enough that no broker will touch it. So the operator files for a fresh MC. New entity name, new paperwork, no history.

The trap is that the new MC looks good. Zero crashes. No out-of-service orders. No violations. Not because the operator is safe, but because the record is three weeks old. A vetting process that only asks "are there any black marks?" will wave a chameleon straight through, every time. The absence of a bad record is not a good record.

What carries over

The reason this is catchable at all is that reincarnation is expensive to do properly, and almost nobody does it properly. A new MC is cheap. A new phone number, a new email, a new yard, a new dispatcher and a new set of trucks are not. So the operator refiles with the same details as before, and the FMCSA record — which is public — quietly links the old entity to the new one:

• The phone number. The dispatch line does not change. Now it appears on the filing of the dead MC and the fresh one.
• The email address. Same, and often worse — one inbox behind an entire stable of shells.
• The address. The yard is the yard. Ten-plus MCs at one address is sometimes a filing agent and sometimes a mail drop with a dozen ghosts behind it.
• The fleet. This is the tell that cannot be faked. A four-month-old authority does not have thirty power units. Legitimate fleets are built truck by truck over years. A brand-new MC with a large fleet is a fleet that already existed under a different number.
• The mileage with no inspections. A carrier reporting six-figure annual miles and zero inspections is either inflating the miles or running them under someone else's authority.

Which rules catch it

No single rule on this page says "chameleon carrier" — that would be a guess, and we do not ship guesses. What the engine does instead is surface the individual facts that a chameleon cannot avoid leaving behind. These are the ones that fire:

Count the points. A textbook chameleon — new authority, twenty-plus trucks, a phone shared with the carriers it used to be — is at Medium on the fleet rule alone, and well past it once the shared contact details land. What the engine cannot do is tell you which dead MC this one used to be. The revocation rule reads the authority history of the docket you looked up, and a freshly-filed docket has none; the only thread we can pull between two carriers is a shared phone, email or address. The badge goes yellow and the factor list tells you precisely why, which is the part you can act on.

What you do next is a phone call. Not to the number in the email — to the number on the FMCSA record. If the person who answers cannot explain why a four-month-old company owns thirty trucks, you have your answer. The same setup is the engine behind most double-brokering schemes, which is worth understanding separately.

A risk level is a prompt to ask a question. That is the whole job. It reads a public record faster than you can and it tells you where the soft spots are. It does not know the carrier, it has never spoken to the carrier, and it cannot see the things that actually decide whether you get your freight delivered.

It is not, and was never designed to be:

• A substitute for a signed carrier packet. The contract is what makes the relationship enforceable. A green badge is not a contract.
• A substitute for a certificate of insurance. We read what the insurer filed with FMCSA. You still want the COI, sent by the agent, naming you.
• A substitute for a phone call to the number on the FMCSA record — not the number in the email signature. That one call defeats a large share of impersonation attempts, because the impostor does not control the real carrier's phone.

Low is not a guarantee

Low means no critical rule fired and the weighted findings did not add up to 2 points. It does not mean the record came back clean — a Low carrier can still be carrying a single 1-point flag, and the panel lists it underneath the badge. Read it. And Low certainly does not mean the carrier is honest, solvent, or going to show up. A carrier with active authority, adequate insurance and a clean inspection history can still no-show your load, and an impostor emailing you from a lookalike domain while impersonating a genuinely low-risk carrier will produce a genuinely low-risk profile. You are vetting an MC number. You are not vetting the person who typed it.

And a good carrier can be flagged

This cuts the other way too, and we would rather say so here than have you discover it on a carrier you have hauled with for six years:

• Shared address. Filing agents and compliance services file for hundreds of carriers from one address. That is the address rule firing on an entirely honest carrier.
• Insurance cancellations. Switching insurers produces a cancellation record. We exclude clean insurer swaps, but the FMCSA data is messy and some legitimate changes still land in the count.
• New authority. Every carrier is new once. A twenty-year owner-operator who finally went out on his own has a six-week-old MC and a perfectly good reason for it.
• Fatal crashes. FMCSA does not record fault. A carrier that was rear-ended carries the same entry as one that caused it.

So the level is a place to start, not a verdict to hide behind. The factor list exists precisely so you can look at the reason, decide it does not apply, and book the load anyway. A broker who understands why the badge is yellow is worth more than a broker who only reads the color.

Every rule on this page reads public FMCSA data. Operating authority, safety rating, crash history and the insurance filings come from the QCMobile API and the Licensing & Insurance system, queried live on each lookup and cached for 24 hours. Contact details, fleet size and reported mileage come from the FMCSA Company Census, which we refresh monthly. The BASIC percentiles are recomputed monthly from FMCSA's public inspection and violation files.

Nothing here is scraped from a private database, and none of it is crowd-sourced. If you want to check our work on a specific carrier, the panel links straight to the FMCSA record it read.
