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.

Last known filings. Insurance for this carrier comes from the FMCSA snapshot of May 14, 2026. Policies may have been cancelled or replaced since. 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 California average covers 398,428 vehicle and 509,934 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
95 violations counted in FMCSA's Safety Measurement System (SMS), 9 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 110 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 ADDT CORP
What does ADDT CORP's operating authority allow?
FMCSA records show no active operating authority for ADDT CORP (MC1634055, FF61763), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about ADDT CORP 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. 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 ADDT CORP?
Confirm the authority and insurance on the Motus record for USDOT 4137437. Call the company back on the phone number on file, (657) 655-9779, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1634055 or FF61763, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
