How to use this inspection record
- Confirm the inspection ID and date. Verify that the inspection number (84605635) and date (May 6, 2025) match what the carrier or broker has provided you. The inspection ID is FMCSA's permanent identifier and will not change.
- Review every cited violation code. Click through each violation code in the table below to read the underlying FMCSR section. The severity weight column tells you which citations carry the most weight in the SMS scoring algorithm.
- Check the OOS flags. An OOS order was issued. The Vehicle OOS / Driver OOS badges at the top of this page tell you which side of the cab triggered it; until the cited defects were corrected, the carrier could not legally continue operating.
- Compare against the carrier's broader inspection history. Open the carrier's full inspection page to see whether this result is typical or an outlier: /usdot/1538326/inspections/
- Cross-reference with SMS BASIC scoring. Open the carrier profile to see how the BASICs cited here aggregate across the carrier's full scoring window: /usdot/1538326/
