No risk signals found
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.
Cargo cover filed: $5,000
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, (712) 657-2981, not a number from an email or load board.
- Check that the MC number you were given is MC197510.
- 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. Cargo cover filed: $5,000.
| Type | Docket | Layer | Insurer | Coverage | Effective | Status |
|---|---|---|---|---|---|---|
| Cargo | MC197510 | — | Great West Casualty Co Policy GWP19082A · BMC-34 | $5,000 | May 8, 2008 | Active |
| Liability (BI&PD) | MC197510 | Primary | Great West Casualty Co Policy GWP19082E · BMC-91X | $1,000,000 | Dec 1, 2015 | Active |

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 Iowa average covers 31,580 vehicle and 64,940 driver inspections of all Iowa-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 Iowa column is the mix across all Iowa-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 DEAN TIEFENTHALER
What does DEAN TIEFENTHALER's operating authority allow?
MC197510: Motor carrier (may haul regulated property for hire).
Which information about DEAN TIEFENTHALER is old or missing?
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 DEAN TIEFENTHALER?
Confirm the authority and insurance on the Motus record for USDOT 195653. Call the company back on the phone number on file, (712) 657-2981, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC197510, and ask the insurer for a certificate of insurance naming you as holder, with cargo coverage that fits your load.
