How to use this inspection record

  1. Confirm the inspection ID and date. Verify that the inspection number (85323989) and date (Jul 22, 2025) match what the carrier or broker has provided you. The inspection ID is FMCSA's permanent identifier and will not change.
  2. 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.
  3. Check the OOS flags. No OOS order was issued, so the carrier was cleared to continue operating after this inspection.
  4. 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/3092522/inspections/
  5. 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/3092522/

Frequently asked questions about this inspection

What does a roadside inspection Level 5 actually inspect? ▾
A Level V (Vehicle-Only) inspection is a vehicle examination performed without the driver present — usually at the carrier's terminal. Inspectors record any out-of-service violations on the spot.
Was this inspection an OOS event for this carrier? ▾
No out-of-service order was issued at this inspection. The carrier and the vehicle were cleared to continue operating.
How does this inspection compare to the carrier's recent record? ▾
In the 90 days leading up to this inspection, this carrier had 2 other inspections with a combined 5 violations and 1 OOS event. Lifetime, the carrier averages 2.00 violations per inspection across 10 prior records.
What violation codes were cited and what do they mean? ▾
4 violations were cited at this inspection. Each row in the Violations Cited table links to the specific FMCSR section: 393.75C-TAOTD-LT1/32, 393.75C-TAOTD-LT2/32, 393.9A-LIL, 393.79.
Is this carrier still operating after this inspection? ▾
An inspection is a snapshot — it does not by itself terminate operating authority. To check current operating status for this carrier, see the live carrier profile, which reflects FMCSA's most recent authority and out-of-service status.
How long does an inspection result stay on a carrier's record? ▾
Inspection records are permanent in FMCSA's Motor Carrier Management Information System (MCMIS). For the purpose of the SMS BASIC scoring algorithm, however, time-decayed weights mean inspections older than 24 months count less, and inspections older than 36 months drop out of the scoring window altogether.
How does this inspection feed into FMCSA's SMS BASIC scoring? ▾
Each cited violation has a severity weight (visible in the Violations Cited table) and a BASIC category (Vehicle Maintenance, HOS Compliance, Unsafe Driving, etc.). FMCSA aggregates these weighted citations across all of a carrier's inspections in the scoring window to produce a percentile score per BASIC. OOS violations carry a +2 weight bump.
Where can I see all inspections for this carrier? ▾
The full inspection history is available at /usdot/3092522/inspections/, including filters for level, state, OOS status, and BASIC category.
