During this one-day unannounced inspection and enforcement campaign, certified commercial motor vehicle inspectors conducted their usual vehicle and driver inspections. They reported brake-related data to CVSA for a one-day snapshot of the state of brake systems on the commercial motor vehicles traversing our roadways every day.

- Other Brake Violations – 368
Examples of other out-of-service brake violations are worn brake lines, broken brake drums, inoperative tractor protection system, inoperative low air warning device, air leaks, hydraulic fluid leaks, etc.
