Operator changes (inspection records)

When consecutive FMCSA inspections list different operating USDOT numbers for this VIN. Common after fleet transfers; can also reflect data-entry errors on rare tickets.

How to read this: FMCSA inspection records show which carrier operated the vehicle on a given date, not the legal owner. A single change may reflect a sale, sublease, or fleet reassignment.

Approximate date From carrier To carrier
Between Aug 22, 2023 and Sep 3, 2024 HMD TRUCKING INC KRC T&T LLC

We say "Sale/auction not necessarily implied" — we see a change in operator USDOT in inspection records, which may indicate a sale, lease, or operational reassignment.

Frequently asked questions about this VIN

What does this VIN's inspection history tell me? ▾
This VIN has been pulled into 4 roadside inspections on record with FMCSA. Each inspection shows the carrier operating the vehicle that day, the inspection level (1 through 6), the violations cited, and whether the vehicle or driver was placed out-of-service. The cross-carrier timeline tells you whether the vehicle has stayed with one operator or moved between fleets.
Has this truck been operated by multiple carriers? ▾
FMCSA inspection records list 2 different operating USDOT numbers for this VIN. That usually means the truck was inspected under more than one fleet (sale, lease, dealer transport, or reassignment). It can also happen if an inspector mistyped a digit on a ticket — open individual inspection rows to verify dates and carriers. These rows are inspection operators, not title holders.
Are there any out-of-service events on this VIN? ▾
No out-of-service events are recorded for this VIN in the inspections shown. That said, individual violations may still have been cited without rising to an OOS order — open the inspection detail page to see the full violation list.
How do I see the full violation list for an inspection? ▾
Click the inspection date in the timeline above to open that inspection's detail page. The detail page lists every violation cited (FMCSR section, severity weight, OOS flag), the inspecting station, and the carrier's other inspections at that station and around that date.
What if this VIN has fewer inspections than I'd expect for its age? ▾
Roadside inspection volume varies a lot by vehicle use. A vehicle in high-mileage long-haul service is inspected more often than a vehicle in local or seasonal use. Inspections also depend on the routes, the carrier's safety profile (which can flag the carrier for more frequent inspection), and where the vehicle crosses scales. A low inspection count is not by itself a sign of anything wrong with the vehicle.
Can I see this VIN's recall remediation status? ▾
This VIN's make/model/year matches 9 open NHTSA recall campaigns. NHTSA does not publish per-VIN remediation status in its public datasets, so we cannot show whether this exact VIN has had the recall work performed. To check completion status, use NHTSA's official recall lookup at nhtsa.gov/recalls or contact the manufacturer with the VIN — we link to the manufacturer page from the recall campaign rows above when available.
