An out-of-service rate is the share of inspections in which a vehicle or driver was placed out of service. With few inspections, one result moves the rate a lot. FMCSA crash records include crashes regardless of fault. None of these figures is a safety rating. The official Satisfactory/Conditional/Unsatisfactory safety rating is issued separately. See SAFER.

Before you work with this carrier
Confirm the safety rating. Authority and insurance are shown or linked 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.
