Active liability insurance
FMCSA cargo filing (BMC-34/83)

No active FMCSA cargo filing on file.

FMCSA L&I filing evidence — not a shipper certificate of insurance (COI). Cargo (BMC-34) is primarily an HHG / household-goods requirement; general freight carriers often have none.

Broker bond / trust (BMC-84/85)

No active broker surety bond or trust fund on file.

BMC-84 is a surety bond; BMC-85 is a trust-fund agreement. Required for property brokers / freight forwarders — not motor-carrier BIPD liability insurance.
