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.

| Liability (BI&PD) | MC544767 | Primary | PROGRESSIVE HAWAII INSURANCE CORP Policy CA1568678 · 91X | $750,000 | Dec 23, 2019 | Active |
Source: Last known · FMCSA snapshot May 14, 2026. Identical filings repeated in the FMCSA data are shown once; a filing listed under two dockets is one policy, not extra coverage. Coverage is the maximum amount filed with FMCSA, not the full policy.

How these rates are calculated
Period: Oct 19, 2024 – Oct 19, 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 Tennessee average covers 76,695 vehicle and 133,874 driver inspections of all Tennessee-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 ↗

"Share" is this company's mix of violations; the Tennessee column is the mix across all Tennessee-based carriers, so you can see which kinds of problems stand out. A high count partly reflects fleet size and how often trucks are inspected.

Questions about DIAMOND TRANSPORTATION LLC
What does DIAMOND TRANSPORTATION LLC's operating authority allow?
MC544767: Contract carrier (may haul regulated property for hire under continuing contracts with specific shippers).
Which information about DIAMOND TRANSPORTATION LLC 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. 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. The MCS-150 was last updated Jul 9, 2024, so fleet size and contact details may be out of date.
What should I verify before booking DIAMOND TRANSPORTATION LLC?
Confirm the authority and insurance on the Motus record for USDOT 1441520. Call the company back on the phone number on file, (865) 851-8184, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC544767, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
