What 171.2F-HMGRMC means in plain language
This citation means the hazardous materials you were transporting did not comply with the Federal Motor Carrier Safety Regulations (FMCSR). Hazmat violations are serious because non-compliant transport of hazardous materials puts drivers, the public, and responders at risk.
The violation covers a broad range of possible failures: materials might be packaged incorrectly, routed improperly, documented inadequately, or transported using a vehicle or carrier setup that doesn't meet hazmat standards. The inspector determined that something about how you or your carrier handled the hazardous cargo fell outside the required framework.
Unlike some hazmat violations that can trigger immediate out-of-service orders, this particular code does not automatically pull your vehicle off the road. However, the underlying issue—whatever specific non-compliance triggered the citation—still needs to be corrected before you haul hazmat again.
What our enforcement data actually shows
Across our 13 million inspection records, this code ranks #1602 out of 3,036 FMCSR codes by citation volume. That means it's uncommon. We've recorded 55 all-time citations for 171.2F-HMGRMC, with 30 citations in the last 12 months and 6 in the last 90 days.
Out of the 55 total citations, only 2 vehicles were placed out of service—an out-of-service rate of 3.6%. For context, the all-FMCSR average OOS rate is 31.4%, so this code triggers out-of-service enforcement far less frequently than most violations. That said, a 3.6% OOS rate still means the violation can be serious enough to sideline your truck; it's just not automatic.
The data shows citations have fluctuated month to month. May 2025 saw a spike with 6 citations, followed by lower counts in subsequent months. Most recently, March 2026 had 4 citations.
Who gets cited most
Our inspection records show California leads with 3 citations in the last 180 days, followed by Oklahoma with 2 citations. Kansas, Oregon, Utah, Ohio, and Florida each had 1 citation over that period. Across all of these top states, no vehicles were placed out of service—all citations resulted in warnings or fines only.
In terms of carriers, our all-time data shows fleets such as JACS Logistics Inc (USDOT 3034175) and TRALO Companies Inc (USDOT 1158934), each with 3 citations. Ellsworth Construction LLC, United Petroleum Transports Inc, and Kangaroo Dreams LLC each have 2 citations. This spread suggests the violation is not concentrated in a single carrier type; it appears across diverse hazmat operators.
How severe is this compared to similar codes
Comparing peer codes in the Hazardous Materials Compliance category shows useful context. 171.2K-HMGRMC (representing a vehicle as carrying hazmat when it doesn't) has 255 citations all-time with a 1.6% OOS rate. 171.2B-HMGRMC (failing to comply with all applicable HM requirements) has 153 citations with a 0.0% OOS rate. 171.2(f)—the non-coded version of your violation—carries 42 citations, also at 0.0% OOS.
Your citation sits in the middle of this range: less common than the broad "representing hazmat" violations but comparable to specific non-compliance codes. The 3.6% OOS rate is slightly higher than most peer codes, which cluster near zero, suggesting that when inspectors cite 171.2F specifically, they occasionally find conditions severe enough to warrant a roadside removal.
How to avoid it
Before your next hazmat run:
-
Verify your shipping papers are complete and legible. Our inspection data shows that missing or inadequate hazmat shipping papers frequently co-occur with general non-compliance citations. Check that the hazard class, division number, and emergency response information are all present and match your cargo.
-
Confirm placard placement and visibility. Inspectors found that improperly visible or missing placards often accompany general hazmat violations. Walk around your vehicle before departure and verify placards are clearly visible from the direction they face and are securely affixed.
-
Ensure your CDL hazmat endorsement is current and valid. Co-occurrence data shows that operating without proper endorsements sometimes pairs with general hazmat violations. Check that your license clearly displays the HM endorsement and has not expired.
-
Review your vehicle's condition against hazmat requirements. Peterbilt and Kenworth models appear in our citation data for this violation. Regardless of make, confirm that your cargo tank (if applicable) is properly certified, that all fittings and closures are secure, and that the vehicle is mechanically sound for hazmat transport.
-
Confirm your carrier has current hazmat authorization. If your motor carrier lacks required permits or hazmat registrations, your load is non-compliant before it leaves the yard. Verify with your dispatcher or safety manager that all carrier-level hazmat credentials are active.
-
Check emergency response information is accessible. Co-occurrence patterns show emergency response data gaps appear alongside general non-compliance. Ensure placards and shipping papers include emergency contact numbers and response procedures.
If you receive this citation, work with your safety manager and legal counsel to identify which specific requirement was missed. The broad wording of 171.2F means the inspector could cite any hazmat step that fell short—but once you know which step, correcting it is straightforward.
