USDOT 4013855MC-Docket MC1512057DENVER, CO
Do not tenderHazmat-authorized56 power units

G4 TANK LINES LLC (USDOT 4013855) in DENVER, CO — 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).
  • Authority revocation is currently pending — carrier may lose operating authority soon.
  • 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.
  • No preventable crashes in the last 24 months; recordable crash rate 0 not elevated.
  • No fatal crashes in the last 24 months.
  • No link to a prior revoked authority.
  • 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.

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.
