How these rates are calculated
Period: Oct 19, 2024 – Oct 19, 2026. Vehicle rate = vehicle inspections with a vehicle out-of-service order ÷ vehicle inspections (levels 1, 2, 5 and 6). Driver rate uses levels 1, 2, 3 and 6. The California average covers 398,614 vehicle and 510,215 driver inspections of all California-based carriers in this period. It mixes every type of operation, so compare with care; rates based on a handful of inspections say little. FMCSA's own SMS measures are weighted differently: SMS profile ↗ · SAFER snapshot ↗
Violations in FMCSA's SMS last 24 months
5 violations counted in FMCSA's Safety Measurement System (SMS), 2 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 8 violations above?
The inspections section's number counts every violation written on the inspection reports in our Oct 19, 2024 – Oct 19, 2026 window. The SMS count comes from FMCSA's own monthly SMS snapshot, which uses its own 24-month window and only the violations it scores. Both are FMCSA figures; they measure different things.

A high count partly reflects fleet size and how often trucks are inspected.
