Thousands of commercial vehicles were removed from the road during a weeklong brake-focused inspection effort in August.
The Commercial Vehicle Safety Alliance (CVSA) released results from this year’s Brake Safety Week, which took place in the U.S., Canada, and Mexico August 23 — 29.
During Brake Safety Week 2026, 2,369 commercial vehicles were taken out-of-service (OOS) for brake violations, a 15.3% OOS rate out of the total number of vehicles inspected.
The CVSA notes that 84.7% of inspected commercial vehicles (13,159 vehicles) did not have any brake-related OOS violations.
See below for results by country.

The area of focus for Brake Safety Week 2026 was on drums and rotors. This year, inspectors uncovered 141 drum and rotor violations, resulting in 64 vehicles being placed OOS.
Additionally, 1,176 were placed OOS for meeting the 20% defective brake criterion, meaning that 20% or more of the vehicle’s, or combination of vehicles’, service brakes had an OOS condition.
See below for more on Brake Safety Week 2026 OOS violations:
- 92 OOS violations for steering axle lining
- 119 OOS violations for other steering axle conditions
