Review before tenderingHazmat-authorized42 power units
KARRENBROCK CONSTRUCTION INC (USDOT 1667753) in WENTZVILLE, MO — has findings to review before tendering. FMCSA authority, fleet size, BASIC safety measures, crash and inspection history.
- Has active operating authority that's tenderable today (common or contract).
- No pending authority revocation.
- Not under an uncleared federal out-of-service or safety action.
- BIPD on file is $750,000 — below your $1,000,000 floor (federal general-freight minimum is $750,000).
- No cargo insurance on file. Required for many shipper contracts.
- No history of insurance lapses.
- Unrated by FMCSA. Most carriers are unrated — unrated is not the same as unsafe.
- No BASIC alerts in any of the five public SMS categories.
- Driver and vehicle out-of-service rate is above the national roadside average.
- 1 preventable crash(es) in the last 24 months; recordable crash rate 1.88.
- No fatal crashes in the last 24 months.
- No link to a prior revoked authority.
- 1 other active carrier(s) operate from this exact street + ZIP. High counts are often legitimate registered-agent / virtual-office addresses — treat as context, not a verdict.
- Crash Indicator and Hazmat Compliance BASICs are statutorily withheld from public SMS under the FAST Act — their absence is not a clean record; use the crash-risk signals above instead. The Hazmat Compliance BASIC is also withheld for this hazmat carrier.
Built from FMCSA's public Safety Management System data — guidance, not legal advice. Verify directly with the carrier and your cargo policy before tendering.
