CVSA posts stats from unannounced brake inspection campaign in May

One more Brake Safety Day planned by CVSA yet this year

Posted July 14, 2017

During an unannounced brake safety day, roadside inspectors found 79 percent of the large trucks and buses examined did not have any critical item vehicle violations.

During the enforcement campaign, which took place on May 3, 2017, more than 9,500 commercial motor vehicles were inspected throughout North America. The event is a part of the Commercial Vehicle Safety Alliance’s (CVSA) Operation Airbrake Program.

Enforcement in 43 jurisdictions (33 in the U.S. and 10 in Canada) used the day to identify out-of-adjustment brakes, and brake-system and antilock braking system (ABS) violations, resulting in 8,140 CMV inspections in the U.S. and 1,384 in Canada.

CVSA reports that vehicles were placed out of service during the one-day event:

  • 21 percent of the time for vehicle violations in general, and
  • 12 percent of the time for brake-related violations.

Many of the jurisdictions reported ABS compliance during the May event, resulting the following data:

Category Number requiring ABS Number with ABS violations
Air-braked trucks and tractors 4,635 8 percent (391)
Trailers 3,222 15 percent (487)
Hydraulic-braked trucks 723 6 percent (41)
Buses 57 11 percent (6)

CVSA indicates that September 7 is the final Brake Safety Day event for 2017.
