From August 23–29, 2026, the Commercial Vehicle Safety Alliance (CVSA) will run its annual Brake Safety Week across the U.S., Canada, and Mexico. For seven days, certified inspectors will pull commercial vehicles in for inspection and any truck with a brake-related out-of-service violation is sidelined until the problem is fixed. This year’s inspection focus is once again brake drums and rotors.
If that sounds like a low-stakes formality, last year’s numbers say otherwise. During the 2025 campaign, inspectors examined 15,175 vehicles and placed 2,296 out of service for brake violations, a 15.1% failure rate, or one in every seven trucks. Brakes are not just a Brake Safety Week problem: during the 2025 International Road Check, brake defects accounted for 41.1% of all vehicle out-of-service violations, the single largest category on the road.
