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 SO average covers 14,101 vehicle and 17,107 driver inspections of all SO-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
321 violations counted in FMCSA's Safety Measurement System (SMS), 33 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 376 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.
