Does NHTSA show DOT roadside inspections?

No. NHTSA vPIC is used to decode a VIN into make, model, year, body class, GVWR, and engine. DOT roadside inspection history comes from FMCSA public inspection records, not NHTSA.

Does FMCSA decode a VIN's specs?

Not really. FMCSA data ties a VIN to roadside inspections, violations, out-of-service events, and carriers. To decode the VIN's make/model/year/GVWR you use NHTSA vPIC.

Where does TruckWhere fit?

TruckWhere combines both: it decodes the VIN with NHTSA vPIC and checks available FMCSA roadside inspection history for that exact 17-character VIN, then interprets it for a used-truck buyer.

Do either of these show title or ownership history?

No. Neither NHTSA nor FMCSA provides title brands, liens, or legal ownership history. For those, use an NMVTIS-approved vehicle-history provider.

NHTSA vs FMCSA VIN Lookup: What Each One Shows

These two official sources answer different questions about a commercial truck VIN. Here's exactly what each shows — and how to use them together.

Last updated: June 2026 · Data sources: NHTSA vPIC (live) and FMCSA public inspection records (periodic refresh).

Quick answer

NHTSA vPIC decodes a VIN into vehicle specs (make, model, year, body class, GVWR, engine). FMCSA public records show DOT roadside inspection history, vehicle-specific violations, out-of-service events, and the carriers observed operating a VIN. NHTSA does not show DOT inspections, and FMCSA does not decode VIN specs. TruckWhere combines both for an exact 17-character VIN.

Side-by-side

Question	NHTSA vPIC	FMCSA public data	TruckWhere
Decode VIN specs	Yes	No	Yes
Make / model / year / GVWR	Yes	No	Yes
Roadside inspections by VIN	No	Yes	Yes (buyer-friendly)
Vehicle-specific violations	No	Yes	Yes
Out-of-service events	No	Yes	Yes
Carrier safety profile	No	Yes (by USDOT)	Yes (as context)
Title brands / liens	No	No	No
Legal ownership history	No	No	No

How to use them together

Decode the VIN with NHTSA vPIC to confirm make, model, year, body class, GVWR, and engine.
Check FMCSA roadside records for the exact VIN to see inspections, violations, and out-of-service events.
Review the carriers observed operating the VIN — context, not ownership.
For title, lien, salvage, theft, or odometer history, use an NMVTIS-approved provider separately.

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 Violations	Violation code, description, OOS status, and unit-level attribution.
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.
