How these rates are calculated
Period: Oct 19, 2024 – Oct 19, 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 South Dakota average covers 5,283 vehicle and 12,000 driver inspections of all South Dakota-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
4 violations counted in FMCSA's Safety Measurement System (SMS), 0 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 16 violations above?
The inspections section's number counts every violation written on the inspection reports in our Oct 19, 2024 – Oct 19, 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.

Source: FMCSA SMS violation file, inspections in the last 24 months, published Oct 19, 2026. "Share" is this company's mix of violations; the South Dakota column is the mix across all South Dakota-based carriers, so you can see which kinds of problems stand out. A high count partly reflects fleet size and how often trucks are inspected.

Questions about H & K OIL INC
What does H & K OIL INC's operating authority allow?
FMCSA records show no active operating authority for H & K OIL INC (MC1822431), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about H & K OIL INC 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 H & K OIL INC?
Confirm the authority and insurance on the Motus record for USDOT 4578976. Call the company back on the phone number on file, (605) 665-2531, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1822431, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
