Results of 2017 Brake Safety Day released by CVSA

Over 7,000 vehicle inspections performed

Posted November 8, 2017

This year’s Brake Safety Day, held on September 7, 2017, throughout the United States and Canada, focused on identifying brake system deficiencies on commercial motor vehicles (CMVs) and resulted in 14 percent of vehicles being placed out of service due to brake-related violations.

The Commercial Vehicle Safety Alliance (CVSA) reports that 7,698 vehicle inspections were performed during Brake Safety Day, with 6,361 inspected in the United States and 1,337 in Canada.

Most of the CMVs stopped during the event did not have any out-of-service conditions. Twenty-two percent of vehicles (1,680) were placed out of service for vehicle violations of any kind. Of those, 1,064 were placed out of service for defective brakes.

Brake Safety Day also provided data on antilock braking systems (ABS). Many participating jurisdictions counted ABS violations, which included when the malfunction lamp did not work or the malfunction lamp stayed on, indicating a fault of some kind.
