Top five hazmat violations roadside inspectors are finding
As we roll into the latter half of 2025, it’s a good time to take stock of how roadside inspections are shaping up for hazardous materials transportation. The Federal Motor Carrier Safety Administration’s mid-year data gives us a clear snapshot of the most common hazmat violations, and where carriers and drivers might want to focus their attention.
Here’s a look at the top five hazmat violations so far this year, based on inspection counts and violation frequency.
1. Improper securement of hazmat (177.834(a))
- Inspections: 1,824
- Violations: 1,879
- Out-of-Service (OOS) violations: 1,865
When hazardous materials aren’t properly secured, it’s a major safety concern, and nearly every time this issue is found it results in an out-of-service order. It’s a clear sign that securement practices need more attention.
2. Missing hazmat registration certificate (107.620(b))
- Inspections: 788
- Violations: 788
- OOS violations: 0
This is a paperwork issue, but it’s still the second most common violation. The registration certificate is a basic requirement and skipping it is an easy way to land on the violation list.
3. Damaged or illegible placards (172.516(c)(6))
- Inspections: 582
- Violations: 614
- OOS violations: 1
Placards are critical for identifying hazards, especially in emergencies. If they’re faded, torn, or hard to read, they need to be replaced.
4. Missing shipping papers (177.817(a))
- Inspections: 575
- Violations: 590
- OOS Violations: 570
Shipping papers are essential for emergency responders and regulatory compliance. Unless there’s an exception, hazmat loads should always have shipping papers.
5. Improperly prepared hazmat (177.801)
- Inspections: 432
- Violations: 581
- OOS violations: 0
These are violations where the driver accepted improperly prepared hazmat.
Total numbers so far
So far in 2025, there have been 97,578 hazmat inspections and 21,002 violations, with 5,238 resulting in OOS orders. These top five violations account for a significant chunk of that activity, and most are preventable with better training, attention to detail, and consistent compliance practices.
Key to remember: Whether it’s securing cargo properly or making sure paperwork is in order, these are areas where small improvements can make a big difference.
