Unannounced initiative produced a 13.5% out-of-service rate
The Commercial Vehicle Safety Alliance reported results from an unannounced hazardous-materials and dangerous-goods inspection initiative conducted June 8–12 in the United States and Canada. Inspectors completed 5,046 commercial motor vehicle inspections and placed 683 vehicles out of service, a combined rate of 13.5%. In the United States, 500 of 4,122 inspected vehicles were placed out of service, compared with 183 of 924 in Canada.
Hazard communication and shipping papers drew violations
Inspectors documented 197 placard violations, including 55 classified as out-of-service conditions, along with 64 marking violations and 32 label violations. They also found 265 shipping-paper violations; 57, or 21.5%, were out-of-service violations. Hazmat shipping papers must accurately communicate the material being transported and include required shipment and emergency-response information, while remaining accessible as required. A missing or incorrect document can delay an emergency response as well as stop a load.
Securement, leaks and emergency information were also cited
The initiative identified 128 out-of-service cargo-securement violations and 29 out-of-service package-integrity violations involving leaks. U.S. inspectors recorded 73 emergency-response-information violations. These categories are operationally connected: packages must remain intact and secured, hazards must be communicated correctly, and responders need usable information if a release occurs. Drivers should not attempt to handle an unknown leak without the training, protective equipment and emergency procedures required for the material.
Credentials and declarations remain part of the inspection
Inspectors found 47 hazardous-materials registration violations, eight hazardous-materials safety-permit violations and 16 hazmat-endorsement violations. They also reported five undeclared packages in the United States. Eligibility depends on the specific material, quantity and operation, so a general statement that a shipment is “hazmat” is not enough to determine every registration, permit, endorsement, packaging or placarding requirement. Carriers and shippers must confirm the applicable rules before dispatch.
Driver and fleet takeaway
Before departure, match the package markings and labels to the shipping description, verify required placards, confirm that shipping papers and emergency-response information are complete and accessible, and inspect packages and securement for movement, damage or leakage. Verify the driver’s CDL endorsement and the carrier’s required registration or safety permit for the load. CVSA issued 1,187 decals during the initiative, but a decal only reflects the eligible inspection at that time; it does not replace the next pre-trip inspection or continuing compliance. If a discrepancy or leak is found, stop the movement safely and follow the carrier’s hazmat emergency and correction procedures before the vehicle continues.
