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.
What to verify next
- Confirm authority and insurance on the official Motus record: our copy is the last known status from May 14, 2026. Safety record: SAFER.
- Call back on the number on file, (617) 625-6060, not a number from an email or load board.
- Check that the MC number you were given is MC143987 or FF36235 or MC143987.
- Ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
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 Massachusetts average covers 21,926 vehicle and 35,924 driver inspections of all Massachusetts-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
23 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 41 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.
