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.

Source: FMCSA Motus · Oct 18, 2026. Identical filings repeated in the FMCSA data are shown once; a filing listed under two dockets is one policy, not extra coverage. Coverage is the maximum amount filed with FMCSA, not the full policy.

Confirm current filings: Motus record ↗ and ask the insurer for a certificate naming you as holder.

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

30 violations counted in FMCSA's Safety Measurement System (SMS), 2 of them serious enough to put the driver or vehicle out of service.

Why is this different from the 44 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.

"Share" is this company's mix of violations; the Iowa column is the mix across all Iowa-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 MS & SONS CORP

What does MS & SONS CORP's operating authority allow?

MC143871: Motor carrier (may haul regulated property for hire).

Which information about MS & SONS CORP is old or missing?

Nothing notable: authority and insurance come from current Motus data and there is enough inspection history to compare.

What should I verify before booking MS & SONS CORP?

Confirm the authority and insurance on the Motus record for USDOT 133751. Call the company back on the phone number on file, (515) 332-3303, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC143871, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.

Other companies using (515) 332-3303

A shared number is common for related companies, dispatch services and family businesses. It is not proof of fraud, but it is worth knowing which company you are dealing with.
