Insurance on file

Liability (BI&PD) pays for injury and damage to other people and property; it does not cover the freight. Cargo insurance covers the freight. FMCSA only requires cargo filings from household goods carriers and freight forwarders, so most carriers file none: ask for a cargo certificate that fits your load. Cargo cover filed: amount not published.

Power units: 4

Includes trailers the company pulled but does not own, such as shipper or leasing trailers.

Shippers named on inspection reports 24 months

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

5 violations counted in FMCSA's Safety Measurement System (SMS), 1 of them serious enough to put the driver or vehicle out of service.

Why is this different from the 4 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.

"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 DECKER TRUCK SERVICE INC

What does DECKER TRUCK SERVICE INC's operating authority allow?

MC171812: Contract carrier (may haul regulated property for hire under continuing contracts with specific shippers).

Which information about DECKER TRUCK SERVICE INC is old or missing?

Operating authority is the last known status from the FMCSA snapshot of May 14, 2026, not a current check. Insurance filings are from the same May 14, 2026 snapshot. There are too few vehicle inspections in the last 24 months to judge the out-of-service rate.

What should I verify before booking DECKER TRUCK SERVICE INC?

Confirm the authority and insurance on the Motus record for USDOT 243873. Call the company back on the phone number on file, (605) 366-4941, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC171812, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
