Reopened, not reformed

A carrier accumulates violations, fails an audit, or draws an unsatisfactory safety rating, and the government revokes its authority. Weeks later, a new carrier appears with the same phone and the same officer or address.

GAO calls these chameleon carriers, and a 2012 U.S. Government Accountability Office study built to detect them (GAO-12-364) found chameleon carriers roughly three times more likely to be involved in severe crashes than other new applicants.

Finding them by the record they tried to leave behind

The method is simple to state. The analysis starts with every carrier FMCSA shut down for cause: put out of service, rated unsatisfactory or unfit, hit with an imminent-hazard order, a denial of access, or an unpaid civil penalty. It then takes every carrier registered since January 2024 and asks whether it shares identifying details with one of those shut-down carriers.

The match required is deliberately strict: the same phone number, plus the same officer name or the same physical address, and the new registration has to appear after the old carrier's shutdown. When a "new" carrier lines up that way with a carrier shut down for cause shortly before it appeared, it counts as a match worth reviewing.

51 of them registered within two years of the shutdown, while the old record was still fresh.

Two things the record confirms on its own

FMCSA's own disclosure field rarely shows these links. Federal registration includes a field for a carrier's prior revoked USDOT number. Of 175 new carriers that share a phone and an officer or address with a carrier shut down for cause, 1 listed a prior carrier in FMCSA's self-reported prior-USDOT field. Cross-referencing surfaces matches the self-reported field does not.

More of them already have a crash on record. Though registered since January 2024, 9.1% already carry a crash record, against 2.55% of all new carriers: 3.6 times as likely. GAO found chameleon carriers about three times as likely to be in severe crashes; that is a different measure, but it points the same way.

How the numbers were checked

1. The analysis uses the record that survives. Inspection history is not retained for dead carriers, so it builds on the crash, out-of-service, and revocation records that are retained, which are also the more meaningful signal: a bad enforcement history, not a recycled phone number.
2. A real reason was required, not a lapse. Most revocations are routine insurance lapses. Only predecessors shut down for cause were counted.
3. A conjunction was required, and the noise excluded. A shared officer name alone is meaningless (common names, filing agents). A match needs a shared phone plus an officer or address, and clusters that look like registered agents were discarded.
4. The match is ordered in time. The successor had to register after the predecessor's shutdown, so the match follows the shutdown, not the other way round.

This mirrors the screening method the GAO itself demonstrated.

Washington has known since 2012

None of this is a secret. The GAO study that produced the 3× crash finding was titled, in full, "New Applicant Reviews Should Expand to Identify Freight Carriers Evading Detection." In 2012, FMCSA's identity-vetting program already covered passenger and household-goods carriers; GAO recommended extending it to freight carriers. Freight carriers, the overwhelming majority of the industry, never got an equivalent screen: FMCSA recorded about 92,000 to 98,000 new interstate USDOT registrations a year from 2023 through 2025 (fleetfax count of the FMCSA census), the prior-authority disclosure is self-reported, and enforcement is built to act on the record a carrier accumulates, not a record tied to another USDOT number.

That is the point of this report. The data to find these matches is public, and the government proved the method more than a decade ago, but nothing in the registration pipeline runs the check. So the burden lands on whoever books the truck. On every carrier you look up, the fleetfax carrier report shows any officer also listed on a revoked carrier when the two also share an address or phone, any trucks last operated by a revoked carrier, and other companies at the same address.
