What 172.202(c) means in plain language
When you're hauling hazardous materials, your shipping papers have to tell the whole story—and they have to tell it completely. Code 172.202(c) covers the required description on those shipping papers. A complete description must include the proper shipping name of the material, the hazard class it belongs to, the UN or NA ID number, and the packing group. If any of those pieces are missing or unclear, you're in violation.
The enforcement system treats this differently than some other hazmat violations. This is a documentation violation—it's about what's written on the paper, not about how the load is physically packaged, placarded, or handled. That distinction matters when it comes to roadside enforcement.
What our enforcement data actually shows
Across our 13 million roadside inspection records, 172.202(c) citations are extremely rare. We have recorded 39 all-time citations for this violation. In the last 12 months, there have been zero citations, and in the last 90 days, also zero. This makes 172.202(c) ranked #1701 out of 3,036 FMCSR codes by citation volume.
The out-of-service rate for this code is 0.0%—none of the 39 drivers cited for 172.202(c) were placed out of service at roadside. This stands in sharp contrast to the all-FMCSR average OOS rate of 31.4%. The rarity of citations and the absence of OOS placements suggest that inspectors rarely catch this violation, or that when they do, they treat it as a correctable documentation issue rather than an immediate safety threat.
Who gets cited most
Because the total citation count is only 39 across our entire database, no single state or carrier dominates. The data shows that citations for 172.202(c) are distributed widely. Our records indicate fleets such as KAG West Energy LLC, Moove NA Transport Inc, and Whatley Oil & Auto Parts Co each received one citation. The vehicle mix is similarly scattered, with Freightliner trailers appearing most frequently (6 citations), followed by Great Dane and Kenworth at 3 citations each.
The lack of concentration means that this violation touches many different operations but rarely becomes a systemic issue at any one carrier or location.
How severe is this compared to similar codes
Other hazmat documentation and handling violations in the same regulatory category show a starkly different enforcement picture. Code 177.834A (general loading/unloading of hazmat) generated 3,954 citations with a 99.2% OOS rate. Code 177.834(a), also covering general loading and unloading, produced 3,839 citations at a 97.9% OOS rate. Even code 172.502(a)(1), which covers placarding general requirements, saw 1,820 citations at an 18.5% OOS rate.
By comparison, 172.202(c) is a low-frequency, low-severity citation. The peer codes show that physical hazmat handling violations (loading, unloading, placarding) are enforced far more aggressively than paperwork defects.
How to avoid it
Preventing a 172.202(c) citation comes down to verifying your shipping papers before you pick up the load and before you roll through any inspection:
-
Check the shipping paper before signing. Every hazardous material listed must include its proper shipping name exactly as listed in the DOT Hazardous Materials Regulations. Do not abbreviate or paraphrase.
-
Verify the UN or NA identification number is present and correct. This four-digit code is non-negotiable. Cross-reference it against the material's proper shipping name if you have any doubt.
-
Confirm the hazard class is listed. This tells inspectors and emergency responders what type of hazard they're dealing with. Missing or wrong hazard classes create confusion at roadside.
-
Look for the packing group. Not all hazardous materials require a packing group, but if one is required, it must be on the paper. Group I is most hazardous, Group III is least.
-
Ask your dispatcher or shipper to correct incomplete papers on the spot. If you catch an error before you leave the facility, have the shipper reissue the shipping papers correctly. Do not accept incomplete paperwork and hope it slides—if you're stopped and found with missing details, the citation is yours.
-
Keep your shipping papers accessible and legible. An inspector cannot cite you for incompleteness if they cannot read what's written. Ensure papers are not faded, smudged, or folded in a way that hides required information.
The fact that this violation is almost never encountered at roadside does not mean you should ignore it. Incomplete shipping papers can lead to delays, fines, and damage to your carrier's safety record.
