Florida Rock & Tank Lines Inc
No risk signals in the last-known data
How risk signals workNothing in the FMCSA record matched our risk signals. That is not a guarantee, and it does not confirm who you are talking to; follow the checks below. Authority and insurance are last known from May 14, 2026.
Cargo cover filed: amount not published
Green means the FMCSA record shows it. It does not confirm who you are talking to, or that a policy covers your specific load.
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, (904) 396-5733, not a number from an email or load board.
- Check that the MC number you were given is MC126736.
- 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. Cargo cover filed: amount not published.

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 Florida average covers 69,887 vehicle and 132,275 driver inspections of all Florida-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
422 violations counted in FMCSA's Safety Measurement System (SMS), 70 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 522 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.

"Share" is this company's mix of violations; the Florida column is the mix across all Florida-based carriers, so you can see which kinds of problems stand out.
