What happened
CVSA says inspectors conducted 15,528 commercial-vehicle brake inspections in the United States, Canada and Mexico during Brake Safety Week from August 23 through 29. They placed 2,369 vehicles out of service for brake-related violations, a 15.3% brake-related out-of-service rate.
Of the total, 13,159 vehicles had no brake-related out-of-service violation. The results describe this defined inspection initiative; they are not a random estimate of every commercial vehicle on the road.
Where the results came from
CVSA reports 14,165 inspections and 2,134 brake-related out-of-service vehicles in the United States, 1,306 inspections and 232 out-of-service vehicles in Canada, and 57 inspections and three out-of-service vehicles in Mexico.
Most inspections were North American Standard Level I inspections. CVSA also reports 141 drum and rotor violations, the campaign's 2026 focus, associated with 64 vehicles placed out of service; a vehicle may have had more than one violation.
What it means for drivers
The most common qualifying condition was the 20% defective-brake criterion: CVSA says 1,176 vehicles met it. Inspectors also recorded out-of-service violations involving steering-axle linings and other steering-axle conditions, air loss, brake hoses or tubes, and other brake-system components.
Drivers should complete required inspections, report warning signs and defects, and keep a vehicle out of service when required. Brake measurement, adjustment and repair should remain with qualified maintenance personnel under the carrier's procedures.
Next scheduled campaign
CVSA has scheduled the next Brake Safety Week for April 18–24, 2027. That future date does not limit routine roadside inspections or a carrier's year-round inspection and maintenance duties.
The published campaign totals do not assign fault to individual drivers or establish the condition of vehicles that were not inspected during the initiative.
