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. No cargo cover filed with FMCSA.

How these rates are calculated

Period: Oct 20, 2024 – Oct 20, 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 California average covers 398,391 vehicle and 509,953 driver inspections of all California-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

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

Why is this different from the 36 violations above?

The inspections section's number counts every violation written on the inspection reports in our Oct 20, 2024 – Oct 20, 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 United Pumping Service Inc

What does United Pumping Service Inc's operating authority allow?

MC429803: Contract carrier (may haul regulated property for hire under continuing contracts with specific shippers).

Which information about United Pumping 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.

What should I verify before booking United Pumping Service Inc?

Confirm the authority and insurance on the Motus record for USDOT 217582. Call the company back on the phone number on file, (626) 961-9326, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC429803, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
