Phantom fleets: 3,025 active US carriers inspected with 3× more trucks than they declared

Investigation · Carrierintel data desk

The carrier with one truck and two hundred and thirty VINs

The FMCSA file for MLTZX GROUP LLC (USDOT 5233773) gives a physical address in Murphysboro, Illinois. Its MCS-150 lists 1 power unit and 1 driver, and on October 26, 2026 its Census status was Active.

In the twelve months to October 26, 2026, its USDOT number appeared on 258 roadside inspections in 42 different US states, all of them between September 28 and October 23. The inspectors recorded 230 distinct 17-character power-unit VINs, with trailers excluded. 131 of those 258 inspections ended with an out-of-service order: 51%, against 20.7% for all US inspections in the same twelve months.

A truck has one VIN for its entire physical life. A carrier that declares one truck and is inspected with 230 may not have declared its fleet, or its USDOT number may be used by other operators who move freight under its authority. In the industry the second pattern is called a chameleon carrier. The inspection data cannot say which applies to a given carrier; it measures the gap. This article measures how often the gap shows up nationally.

What the numbers actually say

We joined every US roadside inspection of the twelve months to October 26, 2026 to each carrier's FMCSA Census record (MCS-150), with the same definition as our phantom fleets report. A carrier is in the set when:

With those filters, the national set is 3,025 active US carriers, in 49 states and DC (New Hampshire has none). Together they declare 4,779 power units and were inspected with 32,766 unique power-unit VINs: 6.9× the declared count. 2,019 of them declare a single truck. 489 show 10× or more. 106 show 25× or more. Nine exceed 100×, led by MLTZX GROUP at 230×.

18,942 of the 54,022 inspections in this set ended out of service: 35.1%, against 20.7% for all US inspections in the same twelve months (a driver, vehicle or hazmat out-of-service order). The data does not say why the rate is higher; it says that it is.

Where the flagged carriers are registered

The largest counts of 3×+ carriers sit in the biggest trucking states: California and Texas first, then Florida, Illinois and New Jersey.

Active carriers with a 3×+ power-unit-VIN-to-declared ratio, by physical-address state, top 10. Twelve-month window ending October 26, 2026. Active Census status, no out-of-service order, 1–10 declared power units. Source: FMCSA roadside inspections, inspection units and Census (open data via Socrata) in the Carrierintel database, inspections 2025-10-26 → 2026-10-26, computed 2026-10-26.

A few notes on the geography. California and Texas combined account for 1,043 carriers, about a third of the national 3×+ set, more than their 21.5% share of the carriers the report draws from. Illinois punches above its weight: 6.5% of the set against 2.3% of that population. Five of the twelve highest ratios are one-truck Illinois carriers; two of them, in Murphysboro and Pecatonica, are small-town Illinois LLCs.

The twelve highest ratios

Here are the twelve carriers with the highest ratio in the set on October 26, 2026. Each was registered Active with no out-of-service order on that date. The table shows only what the FMCSA records say. A high ratio is a signal for review, not a finding about why the gap exists.

VIN counts are unique power units only. "States" is the number of distinct US states that recorded an inspection under the carrier's USDOT number; federal inspections are left out. "OOS" is the number of inspections with an out-of-service order. Source: FMCSA roadside inspections, inspection units and Census (open data via Socrata) in the Carrierintel database, inspections 2025-10-26 → 2026-10-26, computed 2026-10-26.

The patterns inside this table are not subtle:

What a fleet-size mismatch tells you

The data shows the gap, not the arrangement behind it. A declared fleet far below the trucks seen at inspections has several possible reasons: an MCS-150 that no longer describes the fleet, owner-operators leased on, or the pattern the industry calls a chameleon carrier, where other operators move freight under the carrier's USDOT number and authority.

In that last pattern, as it is usually described, operators pay for the use of an active authority and may also rely on the carrier's liability policy. When the record of such a USDOT number turns bad, the operators can move to a new one that starts clean. Our data cannot show any of this for a given carrier.

What the data does show is that the set is young: the median USDOT number among the 50 highest ratios is about 22 months old.

Why this matters to everyone else

When the declared fleet and the inspected fleet differ, the systems that rely on FMCSA data can work from the wrong picture:

What the data can't tell us (yet)

We can measure the gap at scale, with names. The harder question is why any one carrier shows the gap. Three benign explanations exist and we want to name them:

None of the three can be ruled out for a single carrier from inspection data alone. The ratio is a measured gap between two FMCSA records, not a finding about any one carrier.

How to check your own exposure

If you're a broker, shipper, insurer, or factoring company, three checks help you spot a fleet-size mismatch before you work with a carrier:

How we reported this

Every figure in this article comes from public FMCSA data: the carrier census (MCS-150) and the roadside inspection and inspection-unit records that capture a VIN for each unit. We import those datasets every day and join them in our own pipeline. No private data, no interviews used to source numbers; every figure in this piece is reproducible from raw FMCSA files by anyone who's willing to build the joins.

The figures were computed on 2026-10-26 on a replica of our production database, over the inspections of the twelve months to 2026-10-26 (the last one in the data is dated 2026-10-23). They replace the figures first published on June 15, 2026. The SQL is published beside this article in the repository as phantom-fleets-2026.sql.
