Historic National OOS Averages

This view displays the national out-of-service (OOS) averages for driver, vehicle, and hazmat inspections. These averages represent industry-wide safety trends calculated from all inspections in the FMCSA database.

The rates are calculated by counting unique inspections and determining what percentage resulted in out-of-service violations. Driver OOS rates include only driver-level inspections, vehicle OOS rates include only vehicle-level inspections, and hazmat OOS rates include all inspections.

Use this data to understand industry-wide safety trends and compare individual carrier performance against national benchmarks.

OOS rates summarize inspection outcomes; they do not determine why a crash occurred or whether a carrier caused it. For a separate view of reported involvement, explore the Commercial Carrier Crash Monitor, then confirm current carrier context in the FMCSA SAFER Company Snapshot.
