The numbers from the 2026 hazardous-materials inspection initiative should get the attention of anyone pulling hazmat.
During an unannounced June 8–12 enforcement initiative in the United States and Canada, inspectors conducted 5,046 inspections of commercial vehicles transporting hazardous materials or dangerous goods.
683 vehicles were placed out of service.
That's a combined out-of-service rate of approximately 13.5% for the vehicles inspected. The U.S. portion included 4,122 inspections and 500 out-of-service vehicles.
Among the issues reported were problems involving cargo securement, placards, markings, package integrity, and shipping papers.
Shipping paperwork deserves particular attention: inspectors identified 265 shipping-paper violations, including 57 categorized as out-of-service violations.
What the Numbers Actually Mean
A 13.5% out-of-service rate means roughly 1 in 7 hazmat vehicles inspected during this initiative had violations serious enough to take the vehicle off the road.
That's not a small number. It suggests that a meaningful portion of commercial vehicles hauling regulated materials are operating with compliance problems that inspectors consider significant enough to stop the truck.
For drivers who take compliance seriously, this is a reminder that the standards exist for real reasons — and that enforcement is real.
For drivers who haven't been paying close attention to their hazmat compliance, it's a more urgent message.
The Most Common Violation Categories
Understanding what inspectors found helps drivers know where to focus their attention.
Shipping Paper Violations
265 shipping-paper violations were identified, with 57 classified as out-of-service violations. This is the category that deserves the most attention from hazmat drivers.
Shipping papers for hazardous materials must contain specific information required by DOT regulations, including:
- The proper shipping name of the hazardous material
- The hazard class or division
- The UN identification number
- The packing group (when applicable)
- The quantity and type of packaging
- Emergency response information or reference to an emergency response guide
- The shipper's certification (for non-bulk packages)
Errors, omissions, or outdated information on shipping papers are among the most common hazmat violations. The paperwork must accurately describe what's in the trailer — not what was in the trailer on a previous load, not a close approximation, but the actual material being transported.
Common shipping paper mistakes:- Using an outdated or incorrect proper shipping name
- Missing or incorrect UN number
- Incorrect hazard class
- Missing emergency response information
- Paperwork from a previous load that wasn't updated
- Handwritten corrections that create ambiguity
Placard Violations
Placards communicate the hazard class of the material being transported to emergency responders, other drivers, and the public. Incorrect or missing placards are a serious violation because they affect emergency response in the event of an accident.
Placard requirements depend on the specific material, its quantity, and its hazard class. Some materials require placarding in any quantity. Others have threshold quantities below which placarding isn't required.
Common placard mistakes:- Wrong placard for the material being transported
- Missing placard on one or more sides of the vehicle
- Placard that's damaged, obscured, or not clearly visible
- Placard left on from a previous load
- Incorrect orientation or placement
Cargo Securement
Hazardous materials must be properly secured to prevent movement during transport. Cargo securement violations can involve the securing devices themselves (chains, straps, binders), the blocking and bracing of packages, or the overall arrangement of the load.
For liquid bulk tankers, cargo securement involves different considerations than packaged freight — including proper closure of valves, manholes, and vents, as well as the condition of the tank itself.
Package Integrity
Packages containing hazardous materials must be in acceptable condition — no leaks, no damage that compromises the integrity of the package, and no signs of contamination. A package that was in acceptable condition when loaded may not be in acceptable condition after transit.
Drivers should inspect packages at pickup and be alert to any signs of damage or leakage during transport.
Markings
In addition to placards on the vehicle, individual packages of hazardous materials must be marked with specific information including the proper shipping name, UN number, and other required markings depending on the material and packaging type.
Hazmat Isn't the Place to "Figure It Out Later"
Drivers hauling regulated materials already know there's more involved than putting freight in a trailer and heading down the road.
Before moving, documentation needs to be correct. Placards need to be correct. Cargo needs to be properly secured. Packages need to be in acceptable condition. And the driver needs the qualifications required for the operation.
An error that looks small in a yard can become a very different problem during a roadside inspection.
The consequences of hazmat violations are more severe than standard violations. Out-of-service orders stop the truck immediately. Civil penalties for hazmat violations can be substantial. In cases involving willful violations or violations that result in accidents, criminal penalties are possible.
The Pre-Departure Hazmat Checklist
Developing a consistent pre-departure routine for hazmat loads can prevent most of the violations identified in this initiative.
Before accepting the load:- Verify that your hazmat endorsement is current
- Confirm that you have the required endorsements for the specific material (tanker, if applicable)
- Review the shipping papers before the truck is loaded
- Verify that the shipping papers accurately describe the material being loaded
- Confirm that placards are correct for the material and quantity
- Inspect packages for damage or leakage
- Verify that cargo is properly secured
- Confirm that emergency response information is accessible in the cab
- Confirm that all required placards are in place on all four sides of the vehicle
- Verify that shipping papers are accessible and in the correct location in the cab
- Confirm that emergency response information is accessible
- Conduct a final walk-around inspection
- Be alert to any unusual odors, sounds, or handling characteristics that might indicate a problem
- Inspect the load at each stop
- Know the emergency procedures for the material you're hauling
What to Do When the Paperwork Doesn't Match
One of the most important skills a hazmat driver can develop is knowing what to do when something doesn't add up.
If the shipping papers don't match what you believe you're hauling, don't move the truck until the discrepancy is resolved. Contact the shipper and your carrier. Document the discrepancy and the resolution.
If the placard doesn't match the shipping papers, don't move the truck. The placard must match the material.
If packages are damaged or leaking, don't move the truck. Notify the shipper and your carrier. Follow your carrier's procedures for handling damaged hazmat packages.
The inconvenience of resolving a discrepancy before departure is far smaller than the consequences of being stopped during a roadside inspection with violations.
Slow Down Before You Pull Out
The lesson from this initiative isn't to fear inspections.
It's to eliminate preventable problems before the truck leaves.
Inspectors conducting hazmat enforcement initiatives are looking for exactly the kinds of violations identified in this report — shipping paper errors, placard problems, cargo securement issues, and package integrity concerns. These aren't obscure technical violations. They're the fundamentals of hazmat compliance.
Drivers who take the time to verify their documentation, inspect their load, and confirm their placards before departure are doing the work that keeps them out of the 13.5%.
GladHands Pro takeaway: Hazmat doesn't reward shortcuts. A few extra minutes verifying the load, confirming the paperwork, and checking the placards before departure can prevent a much longer stop — and much larger consequences — later.
