How these rates are calculated
Period: Oct 18, 2024 – Oct 18, 2026. Vehicle rate = vehicle inspections with a vehicle out-of-service order ÷ vehicle inspections (levels 1, 2, 5 and 6). Driver rate uses levels 1, 2, 3 and 6. The Iowa average covers 31,594 vehicle and 64,957 driver inspections of all Iowa-based carriers in this period. It mixes every type of operation, so compare with care; rates based on a handful of inspections say little. FMCSA's own SMS measures are weighted differently: SMS profile ↗ · SAFER snapshot ↗
Violations in FMCSA's SMS last 24 months
9 violations counted in FMCSA's Safety Measurement System (SMS), 3 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 24 violations above?
The inspections section's number counts every violation written on the inspection reports in our Oct 18, 2024 – Oct 18, 2026 window. The SMS count comes from FMCSA's own monthly SMS snapshot, which uses its own 24-month window and only the violations it scores. Both are FMCSA figures; they measure different things.

Questions about SIOUX VALLEY CONSTRUCTION LLC
What does SIOUX VALLEY CONSTRUCTION LLC's operating authority allow?
FMCSA records show no active operating authority for SIOUX VALLEY CONSTRUCTION LLC (MC1212655), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about SIOUX VALLEY CONSTRUCTION LLC is old or missing?
Operating authority is the last known status from the FMCSA snapshot of May 14, 2026, not a current check. No insurance filings were found in the public data. There are too few vehicle inspections in the last 24 months to judge the out-of-service rate. FMCSA has not issued a safety rating, which means no compliance review is on record, not that the carrier is unsafe.
What should I verify before booking SIOUX VALLEY CONSTRUCTION LLC?
Confirm the authority and insurance on the Motus record for USDOT 3585538. Call the company back on the phone number on file, (712) 451-9770, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1212655, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
