The Commercial Vehicle Safety Alliance announced that inspectors placed 574 trucks out of service for brake violations in a one-day North American inspection blitz.

Commercial motor vehicle inspectors throughout North America conducted 4,021 inspections of commercial motor vehicles in one day and restricted 574 (14.3%) of those vehicles from travel due to brake-related out-of-service violations. Of the 4,021 total inspections conducted, 3,447 commercial motor vehicles did not have any brake-related out-of-service violations – 85.7% of the total number of vehicles inspected. 

This year, emphasis was placed on drums and rotors. Inspectors identified 43 drum and rotor violations, of which 21 were out-of-service violations. Inspectors identified 313 commercial motor vehicles that met the 20% defective brakes out of-service criterion, which is when 20% or more of the vehicle’s (or combination of vehicle’s) brakes have a condition that impairs braking ability to a degree that the brake is considered defective.

In addition, CVSA said inspectors identified 121 out-of-service violations related to brake hoses and/or tubing, 47 vehicles had steering axle out-of-service violations, 40 vehicles failed an air loss rate test, and there were 193 other out-of-service brake violations, such as inoperative tractor protection system, hydraulic or electric brake violations, inoperative parking/emergency brake, inoperative low-air warning device, etc.
