OOS violations down for 2015, Brake Safety Week data shows

Roadside inspections conducted on nearly 19,000 vehicles

Posted November 2, 2015

The Commercial Vehicle Safety Alliance (CVSA) held its annual Brake Safety Inspection Week, September 6-12, 2015, for North America. Commercial motor vehicle safety inspectors performed brake system safety inspections on 18,817 large trucks and buses.

During the course of the week, a total of 2,321 commercial vehicles were placed out-of-service (OOS) for brake violations. The overall brake violations were down, however, compared to 2014.

OOS rate for: 2015 2014
All break-related
12.3 percent 16.2 percent
7.7 percent 10.4 percent
6.9 percent 9.3 percent

The results came from roadside safety inspections conducted throughout the U.S. and Canada. Safety inspectors looked for:

  • Out-of-adjustment brakes;
  • Loose or missing parts;
  • Air or hydraulic fluid leaks;
  • Cracked, damaged, or work linings;
  • Pads, drums, or rotors; and
  • Faulty brake-system components.

The inspectors also measured the pushrod stroke, where applicable.

Brake Safety Week is part of the Operation Airbrake Program sponsored by CVSA in partnership with the Federal Motor Carrier Safety Administration (FMCSA) and the Canadian Council of Motor Transport Administrators (CCMTA).
