Improper Placarding Top Violation Among U.S. Trucks Transport Topics https://www.ttnews.com/articles/cvsa-hazmat-violations A five-day blitz of surprise inspections for 4,629 commercial vehicles transporting hazardous materials and dangerous goods revealed improper placarding as the top cause for violations issued, the Commercial Vehicle Safety Alliance CVSA announced. Inspectors during a roadside initiative that ran June 9-13 across the United States and Canada discovered 1,169 HM/DG violations, of which 598, or 51%, were out-of-service violations. Forty-five jurisdictions — 35 states and all 10 Canadian provinces — participated in the inspection campaign, but the vast majority of vehicles inspected were in the U.S. In total, CVSA inspectors examined nearly 7,300 HM/DG packages across nine hazardous categories. “The transportation of HM/DG demands rigorous training and heightened compliance requirements. For motor carriers and drivers, safely transporting HM/DG is imperative to the safety of the driver, the public and the environment,” CVSA said. Inspections that uncovered any out-of-service OOS violations — including any not related to HM/DG cargo — resulted in trucks being restricted from further travel until those violations were addressed. Inspectors issued 20 OOS orders for HM/DG package integrity (leaking) violations. There are nine HM/DG categories that group a material’s specific chemical and physical properties, which also have different risks. For instance, Class 1 materials include ammunition, fireworks and flares. Class 2 is for gases, flammable/nonflammable oxygen and inhalation hazards. Class 4 contains flammable solids, while Class 7 encompasses radioactive materials. https://web.archive.org/web/20260511173520/https://www.ttnews.com/articles/cvsa-hazmat-violations 11 May 2026
