Brake Systems Top OOS Violations

GREENBELT, Md. — Brake systems were the leading out-of-service (OOS) violations discovered by the Commercial Vehicle Safety Alliance’s (CVSA) certified inspectors during the May 16-18, 2023 72-hour International Roadcheck inspection and enforcement initiative.

Of the 59,429 commercial vehicles (CVs) inspected, 4,412 had brake-system violations representing 25% of the total vehicle violations discovered during the inspections in the United States, Canada and Mexico.

The overwhelming majority of vehicles inspected, 81%, did not have any violations, according to the CVSA.

A total of 116,669 violations were identified throughout the effort, which included all driver and vehicle out-of-service violations and violations that were not out of service, combined.

Each year, CVSA highlights certain aspects of the roadside inspection. This year, inspectors focused on anti-lock braking systems (ABS) and cargo securement. There were 2,975 cargo securement violations and 4,127 ABS violations – four were discovered on motorcoaches, 1,426 on power units and 2,697 on trailers.

Broken down by country, brake-system violations led the U.S. figures at 25.4% (4,041 violations) as well as in Canada with 23.5% (342 violations). In Mexico, tire issues were number one (34%), with brakes second on the list at 30.95 (though the raw figures were close: 32 vs. 29).
