Review before tendering55 power units
MATHER BROS INC (USDOT 1608441) in RIDGECREST, CA — 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.
- Current BIPD policy (MS TRANSVERSE SPECIALTY INSURANCE COMPANY) was filed 27 day(s) after the last involuntary revocation (2025-08-05) — a refile-to-reinstate pattern worth a closer look.
- 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.
- Vehicle out-of-service rate is above the national roadside average.
- 4 preventable crash(es) in the last 24 months; recordable crash rate 0.
- No fatal crashes in the last 24 months.
- No link to a prior revoked authority.
- Authority involuntarily revoked 11 times, most recent 2025-08-05 — recurring instability (typically insurance-lapse / reinstate cycles).
- 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.
Built from FMCSA's public Safety Management System data — guidance, not legal advice. Verify directly with the carrier and your cargo policy before tendering.
