Before you work with this carrier

Confirm the safety rating. Authority and insurance are shown above — open the SAFER snapshot for the official safety rating and out-of-service status.
Verify insurance is current. Coverage on file can lapse; confirm active BIPD/cargo before tendering a load.
Match authority to the work. For-hire loads need active operating authority — a USDOT number alone isn't enough.
