Over 600 placed OOS in 5-day hazmat inspection blitz

September 16, 2026

Inspectors conducted over 5,000 vehicle inspections across the U.S. and Canada this June to identify violations and improve roadway safety.

This annual unannounced 5-day Commercial Vehicle Safety Alliance (CVSA) inspection event involves having specially trained officers inspect commercial motor vehicles transporting hazardous materials/dangerous goods (HM/DG) for regulatory compliance and placing decals on vehicles without any critical vehicle/cargo tank violations. The 2026 enforcement blitz took place from June 8–12, resulting in 5,046 total inspections.

During the inspection, 1,187 CVSA decals were placed on vehicles, indicating no critical violations. Conversely, inspectors placed a total of 683 vehicles out of service (OOS), resulting in a 13.5 percent international OOS rate.

What makes HM/DG different

Transporting HM/DG requires drivers to undergo serious training thanks to heightened compliance requirements that keep carriers, drivers, the environment, and the public safe. Inspectors look for leaking materials or unsecured cargo, as well as verify shipping paper, packing and loading, labeling, placarding, and marking compliance.

In the U.S., HM refers to any “substance or material that poses an unreasonable risk to health, safety, and property when transported in commerce.” HM is also designated as hazardous under Section 5103 of Federal Hazardous Material Transportation Law. In the U.S., carriers and drivers involved with transporting HM comply with the Hazardous Materials Regulations (HMR), while those in Canada follow the Transportation of Dangerous Good (TDG) Regulations.

There are nine classes of recognized HM/DG, each placed into categories based on the chemical and physical properties of the material, along with the associated risks. There were 5,707 Class 1-9 packages inspected during the event.
