The Commercial Vehicle Safety Alliance (CVSA) recently released the results of its 2026 Brake Safety Week, revealing that 15.3% of commercial motor vehicles inspected were placed out of service for brake-related violations. The annual enforcement initiative, conducted August 23–29, highlights the importance of proper brake maintenance and regular vehicle inspections.
2026 Brake Safety Week Results
During the seven-day inspection campaign, inspectors conducted 15,528 commercial motor vehicle inspections across the United States, Canada, and Mexico. Of those inspections:
- 2,369 vehicles (15.3%) were placed out of service for brake-related violations.
- 13,159 vehicles (84.7%) had no brake-related out-of-service violations.
- 14,165 inspections were conducted in the United States, resulting in a 15.1% brake-related out-of-service rate.
- 91% of inspections were North American Standard Level I Inspections, which examine driver qualifications and vehicle mechanical condition.
Most Common Brake Violations
This year’s Brake Safety Week placed special emphasis on brake drums and rotors. Inspectors identified 141 drum and rotor violations, resulting in 64 vehicles being placed out of service.
Other significant findings included:
- 1,176 vehicles placed out of service for meeting the 20% defective brake criterion, meaning at least 20% of their service brakes had an out-of-service condition.
- 600 violations involving brake hoses or tubing.
- 145 violations involving excessive air loss.
- 119 violations involving steering axle brake conditions.
- 92 violations involving steering axle brake linings.
Inspectors also identified 759 additional out-of-service brake violations involving components such as air tanks, parking brakes, low-air warning devices, and tractor protection systems.
What This Means for Ag Retailers
For agricultural retailers operating commercial vehicles, these findings reinforce the importance of maintaining effective vehicle inspection and preventive maintenance programs. Brake-related violations can result in costly downtime, delivery delays, and increased safety risks.
Ag retailers should take several steps to reduce the likelihood of brake-related violations:
- Conduct Thorough Pre-Trip Inspections: Ensure drivers inspect brake components, air lines, hoses, and other critical systems before operating commercial vehicles.
- Maintain Preventive Maintenance Schedules: Establish regular inspection and maintenance intervals to identify worn or damaged brake components before they become safety hazards.
- Address Defects Immediately: Ensure reported brake deficiencies are evaluated and corrected before vehicles are operated when their condition makes operation unsafe.
- Train Drivers to Recognize Brake Problems: Educate drivers on warning signs such as air leaks, unusual noises, reduced braking performance, and brake warning indicators.
- Maintain Accurate Inspection and Repair Records: Document required inspections, identified deficiencies, and completed repairs to demonstrate compliance with applicable FMCSA regulations.
With approximately one in seven commercial vehicles inspected during Brake Safety Week placed out of service for brake violations, proactive maintenance remains essential. Regular inspections, timely repairs, and driver training can help ag retailers reduce violations, prevent unexpected downtime, and keep their fleets operating safely.
