Unknown
1,342 carriers insured · 1,349 total policies on file with the FMCSA.
Unknown is an insurance provider that files BMC-91, BMC-91X, and BMC-34 forms directly with the Federal Motor Carrier Safety Administration on behalf of motor carriers operating in interstate commerce. We have 1,349 FMCSA policy filings on record for this insurer covering 1,342 distinct motor carriers, with active coverage in 45 U.S. states. A BMC-91 filing is the carrier's federally-required public-liability insurance certificate; the insurer (not the carrier) submits it to FMCSA, and the filing must remain continuously on record for the carrier to keep its operating authority active. Use this page to verify that the insurer behind a BMC-91 filing is still actively filing with FMCSA, look up which carriers it covers, and confirm coverage details before brokering a load.
Major trucking insurer

High filing volume usually reflects a long-running market presence — not necessarily lower risk for any single carrier — so always verify your specific policy on FMCSA's portal before relying on it.

About FMCSA insurance filings
Every for-hire motor carrier operating in U.S. interstate commerce must keep continuous public-liability insurance on file with the Federal Motor Carrier Safety Administration. The insurer — not the carrier — files the proof of coverage using one of three forms: BMC-91 (single primary insurer covering the full required limit), BMC-91X (layered coverage from multiple insurers combining to reach the limit), or BMC-34 (cargo coverage required for household-goods movers). Federal limits range from $300,000 for non-bulk household-goods carriers to $5,000,000 for the most hazardous classes of hazmat.
The filings are publicly recorded in FMCSA's Licensing & Insurance (L&I) system and update within 24 hours of an insurer submitting paperwork. When an insurer cancels a BMC-91 filing, FMCSA gives the carrier a 30-day grace window to file replacement coverage; if no replacement is on file by the end of the window, FMCSA automatically revokes the carrier's operating authority. This is the most common reason MC dockets get revoked — insurance instability rather than safety violations.
TruckCodex mirrors the public L&I filings on a daily refresh cycle. We do not rate, endorse, or verify the financial strength of any insurer in this directory — every record reflects what FMCSA has on file. For ratings, consult A.M. Best or your state's department of insurance. For real-time confirmation immediately before relying on a filing, click through to FMCSA's SAFER portal directly.
