What 172.407(b) means in plain language
172.407(b) is a hazardous materials regulation that addresses specific requirements for how certain dangerous goods must be prepared, packaged, or marked before transport. The rule ensures that materials classified as hazardous are ready for safe movement and that all labeling and documentation requirements are met at the point of loading.
In practical terms, this means your hazmat load must meet federal standards for packaging integrity, proper marking, and labeling before it leaves the shipper's facility. The regulation is part of the Department of Transportation's hazmat framework, designed to protect you, other drivers, and the public from incidents during transport.
What our enforcement data actually shows
Across our 13 million inspection records, 172.407(b) has been cited only once in all-time records, with zero citations in the last 12 months and zero in the last 90 days. This code ranks #2796 of 3,036 FMCSR codes by citation volume—making it among the rarest violations roadside inspectors encounter.
Out of that single all-time citation, it was not placed out of service, resulting in a 0.0% out-of-service rate. For context, the all-FMCSR average OOS rate is 31.4%, so 172.407(b) citations, when they do occur, rarely trigger immediate removal from service. The extreme scarcity of this violation suggests that either shipper compliance is very high, or inspectors rarely have visibility into pre-loading preparation at origin facilities.
Who gets cited most
Our inspection records show one citation for this code across all carriers and states in our database. That citation was issued to a vehicle made by Ford operated under a carrier with USDOT 1435260. Because there is only a single citation on record, we cannot identify meaningful state-level or carrier-level patterns that would help predict enforcement concentration or risk areas.
If you have received a citation for 172.407(b), you are among an extremely small group of drivers cited for this violation. This rarity suggests the violation may have been tied to a specific shipper failure, loading procedure, or documentation gap rather than a widespread enforcement focus.
How severe is this compared to similar codes
Other hazardous materials codes in the same regulatory category show dramatically higher citation volumes and OOS rates. For example, 177.834A and 177.834(a), which address general loading and unloading of hazmat, have 3,954 and 3,839 citations respectively, with OOS rates of 99.2% and 97.9%—meaning those violations almost always result in immediate removal from service.
In contrast, 172.516(c)(6), which addresses placard damage or obscuring, has 1,796 citations but only a 1.6% OOS rate, and 172.602(c)(1), covering maintenance of Emergency Response information, has 1,464 citations with a 0.0% OOS rate. The 172.407(b) enforcement pattern—one citation, zero OOS placements—suggests inspectors view this violation as lower severity than active loading/unloading violations, but the rarity makes direct comparison difficult.
How to avoid it
Because 172.407(b) citations are so rare, the violation likely stems from shipper-side preparation rather than driver-side handling during transport. However, you can protect yourself:
-
Review shipper documentation before accepting the load. Verify that all hazmat labels are present, legible, and correct for the materials declared. Check that placards match the shipping papers. Do not depart if documentation gaps exist.
-
Inspect packaging condition at pickup. Look for damaged, leaking, or compromised containers before loading. Refuse any package that does not appear to meet DOT packaging standards. This protects you from being cited for accepting substandard hazmat at origin.
-
Confirm proper marking on all packages. Each hazardous material must be marked with the proper shipping name, hazard class, and any required technical names. Cross-reference against your shipping papers before departing.
-
Retain shipper certification. The shipper certifies that hazmat has been packaged and marked per DOT rules. Keep that certification and any hazmat paperwork accessible. If you are cited, proper documentation at origin protects you from liability.
-
Ask shipper questions if anything looks wrong. If labeling appears incomplete, markings are faint or missing, or packaging looks damaged, stop. Contact the shipper and get clarification or replacement before you move that load.
The extreme rarity of 172.407(b) citations means most drivers and carriers never see this violation. If you have, focus on the shipper's preparation process—not your driving or in-transit handling—to understand where the failure occurred and prevent recurrence.
