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 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 Rhode Island average covers 3,486 vehicle and 6,899 driver inspections of all Rhode Island-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

3 violations counted in FMCSA's Safety Measurement System (SMS), 1 of them serious enough to put the driver or vehicle out of service.

Why is this different from the 4 violations above?

The inspections section's number counts every violation written on the inspection reports in our Oct 19, 2024 – Oct 19, 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 Rhode Island column is the mix across all Rhode Island-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 DIESEL MAINTENANCE SERVICES LLC

What does DIESEL MAINTENANCE SERVICES LLC's operating authority allow?

MC1270891: Common carrier (may haul regulated property for hire for the general public).

Which information about DIESEL MAINTENANCE SERVICES 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.

What should I verify before booking DIESEL MAINTENANCE SERVICES LLC?

Confirm the authority and insurance on the Motus record for USDOT 3668149. Call the company back on the phone number on file, (401) 649-4900, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1270891, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.

Other companies using (401) 649-4900

A shared number is common for related companies, dispatch services and family businesses. It is not proof of fraud, but it is worth knowing which company you are dealing with.
