Do not book until these are resolved · 1 signal
How risk signals workAt least one fact in the FMCSA record should stop a booking until it is cleared up. Confirm the current record on Motus first; it is not a finding of wrongdoing. Authority and insurance are last known from May 14, 2026.
- Operating authority is not authorized (last known)Without active authority the company may not haul or broker interstate freight for hire.
No cargo cover filed with FMCSA
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, (734) 679-3425, not a number from an email or load board.
- Check that the MC number you were given is MC1361410.
- Ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.

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 Michigan average covers 51,437 vehicle and 85,636 driver inspections of all Michigan-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
14 violations counted in FMCSA's Safety Measurement System (SMS), 4 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 17 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 Groff Transport LLC
What does Groff Transport LLC's operating authority allow?
FMCSA records show no active operating authority for Groff Transport LLC (MC1361410), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about Groff Transport LLC 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. There are too few vehicle inspections in the last 24 months to judge the out-of-service rate. 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 Groff Transport LLC?
Confirm the authority and insurance on the Motus record for USDOT 3791892. Call the company back on the phone number on file, (734) 679-3425, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1361410, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
