Do not tenderHazmat-authorized130 power units

UNIMARK LOWBOY TRANSPORTATION LLC (USDOT 1604546) in PLEASANT PRAIRIE, WI — carries a hard disqualifier. 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: $1,000,000.
  • 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 rates are at or below the national roadside average.
  • 9 preventable crash(es) in the last 24 months; recordable crash rate 0.33.
  • 3 fatal crash(es) in the last 24 months.
  • No link to a prior revoked authority.
  • Authority involuntarily revoked 5 times, most recent 2010-05-05 — recurring instability (typically insurance-lapse / reinstate cycles).
  • 6 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.
