During the week of Sept. 16-22, CVSA-certified enforcement personnel will conduct roadside inspections on commercial motor vehicles in order to identify and remove CMVs with critical brake violations from our roadways and to call attention to the dangers of faulty brake systems.
For safe CMV operation it is crucial to have brakes routinely inspected to insure proper function. Improperly installed or poorly maintained brake systems can reduce braking efficiency, posing serious risk to public safety on our roadways.
Poorly maintained breaks pose a significant safety issue as the following data show:
- According to the U.S Department of Transportation’s Federal Motor Carrier Safety Administration’s Large Truck Crash Causation (LTCC) Study, 32.7 percent of large trucks with pre-crash violations had brake problems.
- Brake-related violations comprised the largest percentage of out-of-service vehicle violations cited during last year’s International Roadcheck.
- The LTCC Study’s relative risk analysis indicated that large trucks involved in a crash where the braking capacity of the truck was critical were 50 percent more likely to have a brake violation than were trucks involved in crashes where the truck’s braking capacity was not critical.
- According to the LTCC Study, of the trucks involved in brake-critical crashes, 45.5 percent had brake violations, compared with 29.9 percent of trucks involved in crashes of the same type where the braking was not relevant.
- Results from last year’s Brake Safety Day found that 14 percent of all inspections conducted during that one-day brake safety initiative resulted in a CMV being placed out of service for brake-related violations.
During Brake Safety Week, inspectors will primarily conduct the North American Standard Level I Inspection, which is a 37-step procedure that includes an examination of driver operating requirements and vehicle mechanical fitness. Inspections conducted will include inspection of brake-system components to identify loose or missing parts; air or hydraulic fluid leaks; defective rotor conditions; measurement of pushrod travel; mismatched air chamber sizes across axles; air reservoir integrity and mounting; worn linings, pads, drums or rotors; required brake-system warning devices; and other brake-system components. Vehicles with defective or out-of-adjustment brakes will be placed out of service.
Brake Safety Week is part of the Operation Airbrake Program, sponsored by CVSA in partnership with the Canadian Council of Motor Transport Administrators and the U.S. Department of Transportation’s Federal Motor Carrier Safety Administration.
