The most common out-of-service violations, 2025

Among the 60 most frequent out-of-service violations recorded in 2025 (611,685 citations), the leading types were tires (25%), brakes (22%), lights (17%), driver’s licenses (9%), cargo securement (8%). Each row below is one violation code; the same defect can be cited on a truck and its trailer.

What the data shows

About one vehicle in 4 inspected is ordered off the road. In 2025, 22.3% of Level I, II and V inspections found a vehicle out-of-service violation, a defect serious enough under the CVSA out-of-service criteria that the truck can’t move until it’s repaired. 6.1% of driver inspections put the driver out of service.

Rates vary widely by state. The highest vehicle out-of-service rates were in Minnesota (40.4%), Nebraska (40.1%), South Carolina (36.5%), Wyoming (35.4%), Iowa (33.9%); the lowest in Mississippi (11.5%), Kansas (11.5%), West Virginia (13.4%), New Mexico (13.9%), District of Columbia (15.1%). For drivers, the highest rates were in Oregon (15.7%), Wyoming (14.3%), Massachusetts (13.7%). Rates also reflect how each state inspects, such as which inspection levels it uses and which vehicles it selects, so they measure enforcement as well as the condition of the trucks.

Most inspections are not the full Level I. Of 2,772,468 inspections in 2025, 24% were Level I, 36% Level II walk-arounds and 37% Level III driver-only checks (what each level covers).

California recorded 442,328 inspections, rank 1 of 51, with a vehicle out-of-service rate of 15.5%.

For a trucking company, every inspection lands on its FMCSA record. Out-of-service violations weigh heavily in the Safety Measurement System behind CSA scores, and underwriters read the same inspection history when they price a renewal. Check any carrier’s inspection record by USDOT number (how CSA scores work; truck insurance; truck crashes by state).

Method and source

All figures come from FMCSA’s Vehicle Inspection File on the Department of Transportation’s open data portal, one record per roadside inspection, queried through its public API (inspections dated through 2026-10-01). States are where the inspection happened. Following FMCSA’s convention, the vehicle out-of-service rate is the share of Level I, II and V inspections (the levels that examine the vehicle) with at least one vehicle out-of-service violation, and the driver out-of-service rate is the share of Level I, II and III inspections (the levels that examine the driver) with at least one driver out-of-service violation. Rates are shown for states with at least 2,000 qualifying inspections. Territories are excluded; the District of Columbia is included. The most common out-of-service violations come from FMCSA’s companion Vehicle Inspections and Violations file, counted by violation code for records entered in 2025; that file has no inspection date, so the entry date is used.
