5 days, over 4,600 vehicle inspections
This year's annual unannounced five-day hazardous materials/dangerous goods (HM/DG) inspection and enforcement blitz took place from June 9-13, 2025, resulting in 4,629 inspections. The Commercial Vehicle Safety Alliance (CVSA) inspection event involves having specially trained officers inspect commercial motor vehicles transporting HM/DG for regulatory compliance and placing decals on vehicles without any critical vehicle/cargo tank violations.
For the 2025 inspection, 831 CVSA decals were placed on vehicles, indicating no critical violations. Conversely, inspectors identified 1,169 HM/DG violations, with 51 percent of those (598) having out-of-service violations. These vehicles were banned from further travel until corrected.
HM/DG Road Blitz goals
The goals of CVSA’s unannounced annual HM/DG Road Blitz include:
- Inspecting vehicles transporting HM/DG for regulatory compliance and identifying compliance violations.
- Removing vehicles with HM/DG out-of-service violations.
- Attaching a decal to vehicles/vehicle combinations without critical inspection violations.
- Recognizing compliant drivers, carriers, shippers, etc.
- Highlighting the importance of the programs associated with safe HM/DG transportation, as well as the specially trained inspectors who focus on HM/DG safety and compliance.
Road Blitz results
During the five-day inspection event, inspectors discovered:
- 16 undeclared packages in the U.S.,
- 35 U.S. drivers with missing copies of their Pipeline and Hazardous Materials Safety Administration (PHMSA) registration,
- 70 U.S. drivers without emergency response information in the vehicle,
- 32 Canadian emergency response assistance violations,
- 61 Canadian TDG training certification violations (64 percent of which placed drivers out of service), and
- Out-of-service violations in both countries for loading and securement and package integrity (leaking packages).
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 7,294 Class 1-9 packages inspected during the event.
