GUARDIAN OILFIELD SERVICES INC
GUARDIAN OILFIELD SERVICES INC (USDOT 1813088) in WEATHERFORD, OK — 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: $3,000,000.
- 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.
- 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 8 times, most recent 2026-03-04 — 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. 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.

Safety & BASIC scorecard
BASIC safety measures
Under the FAST Act, FMCSA publishes an absolute per-category measure (not a 0–100 percentile) for these five BASICs — the alert flag, not the raw number, is the risk signal. The Crash Indicator and Hazmat Compliance BASICs are statutorily withheld from public view.
