Not a live check. FMCSA has not published a Motus record for this carrier, so authority and insurance show the last known status from May 14, 2026. Confirm on Motus ↗ before booking.

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
6 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 20 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 A-1 MODULAR INC
What does A-1 MODULAR INC's operating authority allow?
FMCSA records show no active operating authority for A-1 MODULAR INC (FF56771), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about A-1 MODULAR 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. FMCSA has not issued a safety rating, which means no compliance review is on record, not that the carrier is unsafe. The MCS-150 was last updated Oct 1, 2024, so fleet size and contact details may be out of date.
What should I verify before booking A-1 MODULAR INC?
Confirm the authority and insurance on the Motus record for USDOT 3128988. Call the company back on the phone number on file, (408) 393-8808, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches FF56771, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
