Surprise! Unannounced brake safety event puts nearly 600 OOS

May 21, 2026

An unannounced one-day brake safety event resulted in 574 commercial vehicles removed from roadways across Canada, the U.S., and Mexico on April 14, 2026.

Inspectors conducted 4,021 CMV inspections and found 14.3 percent of commercial vehicles (574) traveling with brake-related vehicle violations. These critical violations resulted in immediate travel restrictions until the violation was corrected.

The top violation of the day, accounting for 313 vehicles, was 20-percent brake violations, meaning "20 percent or more of the vehicle's service brakes had an out-of-service condition resulting in a defective brake."

Brake violation statistics

During Brake Safety Day 2026:

4,021 inspections were conducted.
3,447 commercial vehicles did not have brake-related out-of-service (OOS) violations.
574 commercial vehicles had brake-related OOS violations.
- 313 vehicles had 20-percent brake violations.
- 193 vehicles had “other” brake violations (inoperative tractor protection system, hydraulic or electric brake violations, inoperative parking/emergency brake, inoperative low-air warning device, etc.).
- 121 vehicles had brake violations related to brake hoses and/or tubing.
- 47 vehicles had steering axle OOS violations.
26 (out of 349) performance-based brake testers (PBBT) inspections failed to meet the 43.5-percent minimum required braking efficiency standard and were placed OOS.

What’s Brake Safety Day?

Brake Safety Day is an unannounced, one-day annual inspection blitz conducted by the Commercial Vehicle Safety Alliance's (CVSA's). During that day, CVSA-certified inspectors conduct routine roadside inspections with an extra focus on brake systems and parts. The brake violation data collected from the blitz is then sent back to CVSA to glean more about regulatory compliance and enforcement standards and general safety on the roads.

Brake drum/rotor data

The 2026 Brake Safety focus was brake drums and rotors, which may cause violations or OOS conditions that can impact a motor carrier’s safety rating if not working properly. Inspectors found:

24 rusted rotor violations (all for air disc brakes),
9 broken drum violations (all for s-cam brakes),
8 broken rotor violations (all for air disc brakes), and
2 metal-to-metal contact violations (one from air disc brakes and one from hydraulic brakes).

Overall, there were 43 total violations in all four categories, 21 of which were OOS violations.
