3 ROCKS BIGFORK LLC
Nothing in the FMCSA record matched our risk signals. That is not a guarantee; follow the checks below. Authority and insurance are last known from May 14, 2026. How this works
- Registration (MCS-150) last updated 2 years agoCarriers must update it every two years, so fleet size and contact details may be out of date.
No cargo cover filed with FMCSA
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, (406) 200-0156, not a number from an email or load board.
- Check that the MC number you were given is MC1399346.
- 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.

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.

Roadside inspections Oct 18, 2024 – Oct 18, 2026
No roadside inspections in this period.
How these rates are calculated
Period: Oct 18, 2024 – Oct 18, 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 Montana average covers 4,992 vehicle and 8,429 driver inspections of all Montana-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
No violations recorded in roadside inspections in the last 24 months.
Crashes Oct 18, 2024 – Oct 18, 2026
No reportable crashes in this period.

Questions about 3 ROCKS BIGFORK LLC
What does 3 ROCKS BIGFORK LLC's operating authority allow?
MC1399346: Common carrier (may haul regulated property for hire for the general public).
Which information about 3 ROCKS BIGFORK 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 Jun 4, 2024, so fleet size and contact details may be out of date.
What should I verify before booking 3 ROCKS BIGFORK LLC?
Confirm the authority and insurance on the Motus record for USDOT 3600746. Call the company back on the phone number on file, (406) 200-0156, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1399346, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
