A unit that bounces between many operators can indicate slip-seating, heavy sub-haul, or double-brokering. Review the carrier timeline below for load integrity — context for human judgment, not a verdict.
01

Decoded identity

From the 17-character VIN via NHTSA vPIC

This VIN has not been decoded yet — the unit's carrier, inspection and plate history below is reconstructed from the FMCSA inspection feed regardless.

Decode evidence & sources

Deterministic structure

These fields come directly from VIN positions and the published checksum calculation, with zero store IO.

World manufacturer identifier
1NP

Deterministic · VIN positions 1–3.

Vehicle descriptor section
5LB9X

Deterministic · VIN positions 4–8.

Check digit
4 · valid

Deterministic · position 9; calculated value 4.

Model year candidates
2005 or 2035

Position 10 repeats every 30 years; both candidates are retained and neither is silently selected.

North American serial sequence
842325

Deterministic · positions 12–17 for a North American WMI.

Sourced platform inference

The prefix store publishes only at support ≥ 3 and purity ≥ 90%. Prefix confidence is shown beside every established platform claim.

VIN-level rule claims

Rules published for individual VIN positions beyond the prefix — applied with the WMI, prefix, and model-year guards each rule was validated under. Year-scoped rules were checked against model year 2005, established by the federal observation agreeing with a position-10 candidate.

Temporarily unavailable

The VIN-level rule resolver did not return a reliable response

Deterministic validation and the prefix-level results above are unaffected. An outage here is not evidence that no VIN-level rule applies.

Not established

  • model line
  • generation
  • cab type

These are withheld claims, not negative findings.
