Fleet Watch information
Methods & Assessment
Open this panel to retrieve the active review snapshot and the flagged-carrier distribution. Review priority is not a probability or a federal safety rating.
Evidence, not assumptions.
Automated indicators are investigative leads. A VIN association does not establish ownership, and crash involvement does not establish fault.
Source transparency.
Each section identifies its source, retrieval status and limitations. Missing data is not treated as a clean record.
Public review.
Carrier evidence, scores and explanations are available for public review. Verify each material fact against the dated source record before acting.
Carrier grade.
The Fleet Watch crash-risk grade appears only when a current, validated and source-linked assessment is available. A separate FMCSA-based screening score may also be returned. Neither is an FMCSA safety rating, legal finding, insurance decision or prediction that a carrier will crash.
Inspection assessment.
Rolling inspection graphs use returned six-month and twelve-month vehicle and driver inspection totals. Inspection findings describe conditions documented on the reported date. Missing records, later repairs and source publication delays can affect the displayed history.
Equipment continuity.
Equipment continuity identifies dated VIN, plate or unit associations across carrier records. Those observations may have legitimate explanations, including leases, sales, acquisitions and reporting corrections. They do not establish ownership or wrongdoing.
Repeated movements.
Repeated-movement indicators organize recurring equipment relationships and their dates for review. A sequence such as A → B → C describes reported associations in chronological order; it does not establish a legal transfer or evasion.
Chameleon indicators.
Chameleon indicators are investigative leads derived from returned identity, authority, timing and equipment evidence. They are not an FMCSA chameleon-carrier designation and do not prove that a person or company attempted to evade enforcement.
Corporate records.
Corporate-registry information is attributed to OpenCorporates and the cited public registry when returned. Registered agents, organizers, addresses and name similarities do not independently establish ownership or control. Fleet Watch displays verification status and source dates rather than filling missing information.
Insurance information.
Insurance sections display returned federal filings, limits, effective dates, cancellations and status. A federal filing is not independent confirmation that a particular load, vehicle or event is covered. Current coverage should be verified with the insurer or authorized federal source.
Crash information.
Crash records report federal involvement data and available severity details. Crash involvement does not establish fault, preventability, negligence or legal responsibility.
Refresh and source timing.
The FMCSA Snapshot includes a dedicated refresh control. Other sections show their retrieval status and update when their configured sources publish and Fleet Watch imports the new records. Refreshing cannot make a source publish earlier or eliminate upstream reporting delays.
Photo search and privacy.
Photo search sends the selected image to the configured TWOSU reader to identify visible carrier, VIN, plate, unit or inspection information. Users must confirm the detected identifier before relying on a result. The interface states the configured retention behavior at the point of use.
Corrections and evidence.
Use Feedback and Corrections to identify a disputed record or describe supporting documentation. Verify material facts with the underlying agency, insurer, registry or document before acting.
TWOSU Fleet Review connects dated public-record observations to help users prioritize investigation. Review priority, safety assessment, and operating authority answer different questions and must be read separately.
What the three lists mean
Equipment Continuity Review: unique USDOT entities observed on either side of an interstate equipment relationship. Movement by itself does not establish wrongdoing.
Repeated Movements: unique entities participating in repeated equipment relationships. This includes both source and destination companies; participation does not transfer a source company's violations to its destination.
Flagged Carriers: carrier-level review candidates participating in flagged or repeated R4 relationships. Each USDOT appears once. High, Moderate, and Low describe review priority based on the strongest retained R4 score; they are not probabilities, legal findings, or an FMCSA designation.
Dates, identifiers, and coverage
The system uses up to 24 months of available safety and regulatory history and 36 months of equipment continuity. VIN, USDOT, plate and issuing state, equipment type, and observed dates provide the evidence trail. Inspection sightings bound a possible transition; they do not prove its exact transfer date or ownership.
The regulatory window runs from the recorded notice/service date through 30 days after the recorded effective date. Eligibility and timing checks apply. A notice or a passed effective date does not by itself verify that an action remained in force.
Safety pressure uses a 180-day lookback. The default elevated out-of-service rule requires at least 10 relevant inspections, at least 3 out-of-service inspections, and a rate of at least 30% in the assessed domain. A deterioration indicator compares the preceding period and requires a 15-percentage-point increase with sufficient observations. Repeated defect codes provide context; they do not independently trigger this safety-pressure rule.
How review priority is calculated
The inherited review score takes the strongest qualifying evidence family: regulatory timing 40 points; safety pressure 35; repeated DOT switching 30; serious crash history with linked fleet evidence 30; or successor identity and fleet cluster 25. It does not add all correlated families together. Qualified equipment evidence can add 10 points and an eligible identity family 5, with a 100-point cap.
Repeated DOT switching requires at least 2 qualifying VINs with at least 3 changes within a 180-day window. The successor cluster rule requires at least 3 qualifying VINs, at least 30% of the current reported source fleet denominator, and at least 2 eligible identity families. Registered-agent address alone is not sufficient.
The serious-crash pathway requires at least 3 injury/fatal crash records, at least 0.3 such records per current reported power unit, and linked fleet and identity evidence. Crash records are not findings of fault or preventability. Current fleet size may differ from historical fleet size.
The identity audit can add a review flag where at least two eligible identity families link the entities and dated prior pressure exists. It adds no numeric points, so an identity-based review flag can have a priority of zero. Current identity matches do not establish historical common ownership.
Repeated pressure chains: A → B → C
A scoring chain requires at least two consecutive supported transitions with at least two distinct source DOT numbers, the same valid power-unit VIN, and chronological observations. Each source must have its own qualifying pressure. For this chain rule, safety evidence must precede the last source observation. Neutral, excluded, unsupported, or ambiguous steps break the scoring chain. Transition and inter-step gaps are limited to 365 days.
The chain bonus is 10 points for two supported legs, plus 5 for each additional leg, plus 5 where multiple qualifying VINs support the pair, capped at 30. The calculation is: the larger of the previous score and the smaller of 95 and [the larger of the previous score or 40, plus the bonus]. A prior score above 95 is preserved. Overlapping chains are not independently summed.
Plate-only and trailer chains can provide supporting context but do not receive this power-unit VIN chain bonus. The model does not infer that a business closed, reopened, changed signs roadside, or intended to evade enforcement without separate evidence.
Probability assessment
A probability of chameleon activity is not yet calibrated. A priority of 70/100 does not mean a 70% probability of fraud. The graph below shows the actual distribution of flagged-source review priorities in the active snapshot. It is not a prediction curve, accuracy estimate, or confidence interval.
Reliable probability estimates require independently reviewed examples, legitimate-operation controls, and validation on a separate sample. The carrier safety panel may show a separately identified crash model; that estimate must not be treated as a chameleon probability.
Ownership, corporate registry data and attribution
Fleet Review may use OpenCorporates to locate company-registration records and officer, management, formation and registered-agent roles returned from public corporate registries. OpenCorporates is used as a registry discovery and provenance layer; the cited underlying registry remains the authoritative filing source where available.
Attribution: OpenCorporates-derived records are identified as registry data, preserve the source publisher and retrieval date when returned, and link to the OpenCorporates company record when available. OpenCorporates data is used under its applicable open-data attribution/share-alike terms.
TWOSU analysis remains separate: Fleet Review independently compares corporate records with FMCSA registration, inspection, equipment-continuity and other public evidence. OpenCorporates does not create or endorse TWOSU safety scores, review priorities, successor/chameleon indicators or investigative conclusions. Officers, presidents, incorporators, organizers and registered agents are not automatically treated as owners. Equipment associations, shared contacts and matching addresses do not independently establish ownership or control.
Documented legitimate relationships and configured leasing exclusions must be considered. Sales, leasing, affiliated entities, and different operating classifications can explain movements. Missing data is not a clearance, and a review flag is not a legal finding.
Check the dated evidence and source records before making a decision. Use Send Feedback to identify an incorrect association or supply a documented explanation. The dates and counts below describe a completed snapshot, not continuous real-time tracking.
