Brake Safety Week Finds 84.7% of Inspected Trucks Free of OOS Brake Violations

Most commercial vehicles checked during the 2026 Brake Safety Week inspection campaign had no brake-related out-of-service violations. TheTrucker.com reported November 8 that inspectors examined 15,528 vehicles across the United States, Canada and Mexico, with 13,159 vehicles, or 84.7%, clearing the brake portion without an out-of-service condition.

The official Commercial Vehicle Safety Alliance results show that 2,369 vehicles were placed out of service for brake violations, a 15.3% rate. U.S. inspectors completed 14,165 of the inspections and placed 2,134 vehicles out of service, producing a 15.1% U.S. rate. Fifty-one jurisdictions participated during the August 23-29 campaign. About 91% of all checks were full North American Standard Level I inspections.

Inspectors concentrated on drums and rotors and documented 141 violations in those components, with 64 vehicles placed out of service. Nearly half of all brake-related out-of-service vehicles met the 20% defective-brake criterion, meaning at least one-fifth of the service brakes on the vehicle or combination had an out-of-service condition. Inspectors also recorded 600 out-of-service violations involving brake hoses or tubing.

The results are a one-week enforcement snapshot, not a failure rate for every truck on the road. Drivers should still check air pressure buildup, warning devices, visible hoses, chambers and accessible components during pre-trip inspections and report defects immediately. Fleets should track recurring adjustment, lining and air-loss findings and repair them before dispatch. CVSA has scheduled the next Brake Safety Week for April 18-24, 2027, but brake compliance remains a year-round roadside inspection priority.
