NHTSA VIN Decoder for Commercial Trucks
The NHTSA vPIC decoder turns a commercial truck VIN into manufacturer specs. TruckWhere uses it — and adds the FMCSA roadside inspection history a decode alone can't show.
Last updated: June 2026 · Data sources: NHTSA vPIC (live) and FMCSA public inspection records (periodic refresh).
Quick answer
NHTSA's vPIC is the official VIN decoder. For a commercial truck it returns make, model, model year, body class, GVWR, and engine details. It does not show DOT roadside inspection history — that comes from FMCSA. TruckWhere combines the NHTSA decode with FMCSA roadside records for the exact VIN.
Free FMCSA roadside summary. We accept exact 17-character VINs only and never silently correct a VIN.
What NHTSA vPIC decodes
- Make, model, and model year
- Body class and vehicle type (e.g., truck-tractor)
- GVWR class and, where available, engine details
- Plant and manufacturer information
What a decode can't tell you
A VIN decode shows what the truck is — not how it was operated. For roadside inspections, violations, and out-of-service events tied to the VIN, you need FMCSA data. TruckWhere adds that layer.
Data sources used by TruckWhere
| Source | Used for |
|---|---|
| NHTSA vPIC | VIN decode: make, model, model year, body class, GVWR, engine, and manufacturer details. |
| FMCSA Inspection data (SAFER / A&I) | Roadside inspection records. |
| FMCSA Inspections Per Unit | VIN, unit number, plate state, and carrier/USDOT association. |

| FMCSA Company Snapshot / Census (SAFER) | Carrier legal name, DBA, USDOT number, fleet size, crash summary, and safety rating where available. |
TruckWhere uses exact 17-character VIN matching only — no fuzzy matching, no silent VIN correction, and no assumption that a carrier observed operating a VIN legally owned the truck.
