1991 POLAR TANK TRAILER Polar Tank Trailer

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.

Inspection records show this VIN operated by a single carrier so far. That doesn't rule out earlier or later carriers we haven't yet observed in inspection data.

Yes. FMCSA records show 2 inspections where this VIN was placed out-of-service overall. An out-of-service order means the vehicle, driver, or both were ordered off the road until the cited defect was corrected. The timeline above marks each inspection's OOS state.

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.

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.

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.
