Mack MD VIN Lookup with DOT Inspection History
Decode a Mack MD VIN free, then check its DOT roadside inspection history, violations, and out-of-service events for the exact VIN — built on official NHTSA and FMCSA public data.
Last updated: June 2026 · Data sources: NHTSA vPIC (live) and FMCSA public inspection records (periodic refresh).
Quick answer
A Mack MD VIN lookup with TruckWhere decodes the 17-character VIN using NHTSA vPIC data and checks available FMCSA roadside inspection records for that exact VIN. Results can include the VIN decode, DOT inspections, vehicle-specific violations, out-of-service events, and carriers observed operating the VIN. It is not a title, lien, auction, ownership, or complete odometer-history report.
Free FMCSA roadside summary. We accept exact 17-character VINs only and never silently correct a VIN.
About the Mack MD
The Mack MD Series is the brand's Class 6–7 medium-duty entry for distribution and vocational bodies.
Segment: medium-duty (Class 6–7) commercial truck. Built by Volvo Group. Common Mack WMIs: 1M1, 1M2, VG6.
What to verify on a used Mack MD
Based on its segment (medium-duty (Class 6–7) commercial truck), prioritize these checks — and use the VIN's actual roadside history to focus your inspection:
- Brake condition and adjustment
- Tire tread depth and wheel/rim condition
- All required lamps and reflectors
- Body/upfit mounting and any prior inspection violations
Mack VIN decoder chart
Every Mack VIN has 17 characters. Each position encodes specific information, following the North American FMVSS / ISO 3779 standard:
| Position | Meaning | What it tells you |
|---|---|---|
| 1 | Country of origin | Where the vehicle was built (e.g. 1/4/5 = United States, 2 = Canada, 3 = Mexico, J = Japan). |
| 2 | Manufacturer | Identifies the manufacturer of the vehicle. |
| 3 | Vehicle type / division | Manufacturer division or vehicle type. Positions 1–3 together form the World Manufacturer Identifier (WMI). |
| 4–8 | Vehicle descriptor (VDS) | Model, body style, cab type, engine, GVWR class, and brake system. |
| 9 | Check digit | A calculated digit (0–9 or X) that validates the VIN against transcription errors. |
| 10 | Model year | The model year — see the model-year code chart below. |
| 11 | Assembly plant | The manufacturing plant where the vehicle was assembled. |
| 12–17 | Serial number | The unique production sequence number for this specific vehicle. |

TruckWhere vs other Mack VIN lookup options
TruckWhere is built for one job: checking available DOT roadside inspection history for a commercial truck by exact VIN. Other tools serve different jobs.
| Tool type | Best for | Limitation |
|---|---|---|
| NHTSA VIN Decoder | Official VIN decode | No buyer-friendly DOT roadside history |
| FMCSA SAFER / SMS | Carrier-level safety lookup | USDOT/company based, not a used-truck VIN report |
| RigDig | Broad commercial truck history | Broader report; not focused only on exact-VIN DOT interpretation |
| Truckchex | Heavy-duty truck title/history report | More title/history oriented than DOT-roadside focused |
| VINData | Vehicle-history & commercial-truck records | Broader vehicle-history category |
| Generic VIN decoders | Basic specs and general history | Usually not focused on FMCSA roadside patterns |
| TruckWhere | Exact-VIN DOT roadside history for commercial trucks | No title brands, liens, auction records, or full odometer history |
Need title, lien, salvage, theft, or odometer history? Use an NMVTIS-approved vehicle-history provider — that is a different lane from TruckWhere.

Used Mack trucks buyers, sellers, fleets, inspectors, and lenders who want to check available DOT roadside inspection history for an exact VIN.
Not best for

Frequently asked questions
- How do I look up a Mack MD by VIN?
- Enter the exact 17-character VIN above. TruckWhere decodes it with NHTSA vPIC and checks available FMCSA roadside inspection history for that specific Mack MD VIN.
- Is a MD VIN check different from a generic VIN decoder?
- Yes. A generic decoder only returns specs. TruckWhere adds the Mack MD's available DOT roadside inspection history, vehicle-specific violations, and out-of-service events for the exact VIN.
- Does no FMCSA record mean a MD is clean?
- No. No matching FMCSA record means no exact VIN match was found in the available roadside data. It does not prove the truck is clean.
