Frequently Asked Questions

What is an out-of-service rate?

An out-of-service (OOS) rate is the percentage of roadside inspections in which an FMCSA inspector found critical safety violations serious enough to take the vehicle or driver out of service — meaning they cannot continue driving until the issue is corrected. A higher OOS rate indicates more frequent safety violations.

Which state has the highest truck OOS rate?

Based on FMCSA data, SV has the highest OOS rate at 400%. The national average is 38.3%. A high state-level OOS rate does not mean every carrier in that state is unsafe — it reflects the aggregate across all carriers registered there.

Where does this data come from?

This data is sourced from the FMCSA Motor Carrier Census and inspection records — public datasets released by the US Department of Transportation. OOS rates are calculated from total inspections and out-of-service findings for each state. Data is updated monthly.

About This Ranking

This ranking compares US states by their average out-of-service rate — the percentage of FMCSA roadside inspections that result in a vehicle or driver being placed out of service due to critical safety violations.

Only states with at least one inspected carrier are included. OOS rates reflect aggregate state-level performance and are influenced by enforcement patterns, freight types, and carrier compliance. The national average across all ranked states is 38.3%.
