Public domain (U.S. government work). Inspection and crash counts cover November 7, 2024 to November 7, 2026. Fleet size, drivers, cargo and operation are as each carrier reports them to FMCSA and can be out of date. A vehicle or driver out of service order means an inspector ordered the vehicle or driver off the road until the problem was fixed. The national rate comes from every inspection in the same window. Crashes are those state police reported to FMCSA and are not a finding of fault.
