North American truck and bus inspectors placed more than 12,000 vehicles out-of-service during their 72-hour Roadcheck enforcement blitz held June 6-8. Another nearly 3,000 drivers were placed out-of-service during the week-long event.

Enforcers in sum conducted 62,013 inspections. Of those, 19.4 percent (12,030) resulted in a vehicle out-of-service order, and 4.7 percent (2,940) resulted in a driver out-of-service order.

The top three out-of-service vehicle violations were for brake systems (26.9 percent of vehicle out-of-service violations), cargo securement (15.7 percent) and tires/wheels (15.1 percent).

The top three driver-related violations were for hours of service (32.3 percent of driver out-of-service violations), wrong class license (14.9 percent) and false log book (11.3 percent).

In last year’s Roadcheck, inspectors performed more inspections, but placed fewer trucks and drivers out of service.
