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.
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, (920) 573-7931, not a number from an email or load board.
- Check that the MC number you were given is MC1478940.
- 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.
Last known filings. Insurance for this carrier comes from the FMCSA snapshot of May 14, 2026. Policies may have been cancelled or replaced since. Confirm current filings: Motus record ↗ and ask the insurer for a certificate naming you as holder.

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 Wisconsin average covers 42,165 vehicle and 76,889 driver inspections of all Wisconsin-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
16 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 26 violations above?
The inspections section's number counts every violation written on the inspection reports in our Oct 18, 2024 – Oct 18, 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 Wisconsin column is the mix across all Wisconsin-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 RIO FAST LLC
What does RIO FAST LLC's operating authority allow?
MC1478940: Common carrier (may haul regulated property for hire for the general public).
Which information about RIO FAST 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 RIO FAST LLC?
Confirm the authority and insurance on the Motus record for USDOT 3963612. Call the company back on the phone number on file, (920) 573-7931, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC1478940, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
