5InspectionsFMCSA roadside, 24 months

1 of 2Vehicle inspections with an out-of-service orderToo few inspections for a meaningful rate

0 of 5Driver inspections with an out-of-service orderToo few inspections for a meaningful rate

Source: FMCSA Safety Measurement System, roadside inspections and crashes over a ~24-month window, checked October 4, 2026. 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.
