On June 13-17, commercial motor vehicle inspectors inspected 6,204 vehicles transporting hazardous materials/dangerous goods (HM/DG) in Canada and the U.S. during an unannounced inspection and enforcement initiative for the Commercial Vehicle Safety Alliance. The total number of violations was 1,774.
During the 2022 HM/DG Road Blitz, inspectors discovered the following HM/DG violations:
408 shipping papers violations
269 non-bulk/small means of containment packaging violations

CVSA’s HM/DG Road Blitz spotlights the safety-compliant drivers, shippers and motor carriers that ensure HM/DG are always appropriately marked, placarded, packaged and secured while being transported on our roadways.
Vehicles found to have HM/DG-related out-of-service violations, and/or any other driver or vehicle out-of-service violations, were restricted from traveling until all out-of-service violations were addressed.
