What 172.407(c) means in plain language
172.407(c) is a hazardous materials regulation under Title 49 of the Code of Federal Regulations. It addresses specific requirements related to how hazardous materials must be documented, packaged, or transported in commercial vehicles. The regulation sets a baseline standard to ensure that hazardous cargo is handled safely from the point of origin through delivery.
This code applies to any driver or fleet transporting materials classified as hazardous under federal definitions. The requirement is straightforward: compliance must be verified before the vehicle leaves the shipper's facility and maintained throughout transport. Non-compliance puts the driver, the public, and the shipment at risk.
What our enforcement data actually shows
Our inspection records show that 172.407(c) is rarely cited on American roadways. Across our database of 13 million+ inspections, this code has generated only 1 citation all-time, with 0 citations issued in the last 12 months and 0 in the last 90 days. That makes 172.407(c) ranked #2796 of 3,036 FMCSR codes by citation volume—placing it in the lowest-enforcement tier.
When the single citation was issued, the driver was not placed out of service. Our data shows a 0.0% out-of-service rate for this code, compared to the all-FMCSR average of 31.4%. This low OOS rate does not indicate leniency on hazmat violations; rather, it reflects the rarity of the citation itself. Most drivers and fleets correctly interpret and follow the rule, so inspectors rarely encounter violations.
The very low enforcement volume suggests that when this violation does occur, it may be part of a larger compliance breakdown rather than an isolated mistake. That said, the scarcity of citations should not breed complacency—hazmat violations carry significant liability and regulatory consequences regardless of how often they appear in roadside data.
Who gets cited most
Our records show only one carrier with a citation for 172.407(c): Clinton Helget (USDOT 1883384), with 1 citation. Because the overall citation count is so low, state-level breakdown and multi-carrier comparison would not be statistically meaningful. Instead, focus on the fact that if you operate in hazmat transportation, this rule applies to you equally, regardless of fleet size or state of operation.
How severe is this compared to similar codes
To understand where 172.407(c) sits in the hazmat enforcement landscape, compare it to related placarding and loading regulations:
- 177.834A-HMC (General loading/unloading hazmat) has generated 3,954 citations with a 99.2% out-of-service rate—the most heavily enforced hazmat code in the category.
- 172.502(a)(1) (Placarding general requirements) shows 1,820 citations with an 18.5% out-of-service rate, indicating moderate enforcement with moderate severity.
- 172.516(c)(6) (Placard damaged, deteriorated, or obscured) has 1,796 citations but only a 1.6% out-of-service rate, suggesting inspectors often view these violations as correctable on the spot.
172.407(c) enforcement is dramatically lower than these peer codes, but that reflects rarity, not permissiveness. When hazmat loading and placarding violations do occur in the database, they are almost always out-of-service events. The low citation count for 172.407(c) implies that drivers are generally meeting the standard—or violations cluster under other, more commonly cited codes in the same family.
How to avoid it
If you haul hazmat, build these practices into your pre-trip and shipper-coordination routine:
- Verify shipper compliance before loading. Do not accept hazmat cargo unless the shipper has provided proper documentation and you have confirmed that the materials are correctly classified, marked, labeled, and placarded according to federal definitions.
- Review the hazmat manifest for accuracy. Cross-check the material descriptions, quantities, and classifications on the bill of lading against the actual cargo. Misclassification is a common entry point for violations.
- Inspect placards and labels before departure. Ensure all required placards are affixed, legible, and in the correct orientation. Faded, missing, or damaged placards can result in citations under related codes—and are far more commonly enforced than 172.407(c) itself.
- Know your vehicle's hazmat limitations. Certain hazmat materials cannot be transported in certain vehicle types. Before accepting a load, confirm your truck or trailer is authorized for the cargo class.
- Document your pre-trip inspection for hazmat loads. Record that you visually verified placarding, packaging integrity, and shipper compliance. This creates a defense if a violation occurs despite your diligence.
- Stay current on hazmat updates. Regulations change annually. If you transport hazmat, refresh your knowledge at least once per calendar year or after any federal rule change.
The rarity of 172.407(c) citations in our data means most professional hazmat drivers are getting this right. Maintain that standard by treating every load as a full-compliance checkpoint, not a paperwork formality.
