How these rates are calculated
Period: Oct 18, 2024 – Oct 18, 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 Maryland average covers 42,318 vehicle and 51,664 driver inspections of all Maryland-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
19 violations counted in FMCSA's Safety Measurement System (SMS), 4 of them serious enough to put the driver or vehicle out of service.
Why is this different from the 22 violations above?
The inspections section's number counts every violation written on the inspection reports in our Oct 18, 2024 – Oct 18, 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.
