Review before booking · 2 signals
How risk signals workFacts from the FMCSA record that call for a closer look. They are not a finding of wrongdoing.
- Phone number shared with 6 other companiesNormal for dispatch services and related companies, but confirm who you are talking to.
- 6 other companies list the same addressCommon for registered-agent offices, mail drops and truck yards. Confirm the company operates from where it says.
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.
What to verify next
- Confirm authority and insurance on the official Motus record. Safety record: SAFER.
- Call back on the number on file, (262) 564-7282, not a number from an email or load board.
- Check that the MC number you were given is MC593409.
- 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.
| Type | Docket | Layer | Insurer | Coverage | Effective | Status |
|---|---|---|---|---|---|---|
| Liability (BI&PD) | MC593409 | — | LM Insurance Corporation Policy 016242671 · BMC-82 | $1,000,000 | Dec 19, 2023 | Active |
Source: FMCSA Motus · Oct 20, 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.
Confirm current filings: Motus record and ask the insurer for a certificate naming you as holder.

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 Wisconsin average covers 42,218 vehicle and 76,954 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
62 violations counted in FMCSA's Safety Measurement System (SMS), 15 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 106 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 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.
