Direct answers grounded in TruckCodex inspection data
No. Across our 13 million inspection records, 172.322(c) has never resulted in an out-of-service placement. Our data shows a 0.0% OOS rate for this violation—meaning all 2 citations on record were issued but the vehicle remained in operation.
For context, the national average OOS rate across all FMCSR codes is 31.4%, so 172.322(c) is significantly less likely to trigger an OOS order than most violations.
Much less serious than related hazmat violations in the same category. Our inspection records show 172.322(c) ranks #2651 of 3,036 FMCSR codes by citation volume, with only 2 all-time citations.
Peer hazmat violations are far more common: placarding violations (177.817(a)) have 2,274 citations with 75.1% OOS rate; general loading violations (177.834A-HMC) have 3,954 citations with 99.2% OOS rate. By comparison, 172.322(c) is rarely cited and almost never results in roadside enforcement action.
Our inspection database does not show geographic concentration for 172.322(c). With only 2 all-time citations in 13 million records, this violation is so rare that state-level tracking is not meaningful.
The two citations on record were issued to carriers TFORCE FREIGHT INC (USDOT 121058) and KEEN TRANSPORT & LOGISTICS INC (USDOT 3008274). If you're concerned about hazmat compliance in your region, monitor more common violations like 177.817(a) (placarding, 2,274 citations) and 177.834A-HMC (loading/unloading, 3,954 citations).
Low urgency for repair, but high urgency for documentation. Since 172.322(c) has a 0.0% OOS rate and no citations in the last 90 days across our 13 million records, you are unlikely to face immediate removal from service.
However, address the underlying compliance issue promptly. Work with your carrier's hazmat coordinator to correct whatever triggered the citation—whether documentation, labeling, or packaging—so it doesn't recur and doesn't accumulate on your CSA record.
Yes, if the citation is factually incorrect. FMCSA's DataQs system allows carriers and drivers to challenge roadside inspection findings within 90 days. Your contestation must be evidence-based—for example, if the inspection recorded the wrong vehicle ID, wrong cargo description, or misidentified equipment.
DataQs is not for disputing the regulation itself, only for correcting inspection facts. Submit your challenge through your carrier's CSA account with supporting documentation (photos, manifests, maintenance records). Since 172.322(c) citations are extremely rare, your carrier likely has legal/compliance staff who can guide the process.
Our data shows 2 Freightliners cited for 172.322(c), along with 1 Hyundai trailer and 1 Wabash trailer. The sample is too small to identify a pattern—only 2 citations across all vehicles.
If you drive a Freightliner or similar commercial tractor, standard hazmat compliance (proper placarding, documentation, packaging) will keep you compliant. Most violations occur on equipment that hasn't been regularly inspected or maintained for hazmat service.
Both. FMCSA's safety evaluation system (CSA) tracks violations at the carrier level (Safety Management BASIC) and, in many cases, at the driver level (Driver Fitness BASIC). A 172.322(c) citation will appear on your carrier's CSA record and may appear on your individual record, depending on FMCSA's assignment of responsibility.
Your carrier's safety manager will typically review who was at fault—driver, loader, maintenance—and may assign corrective action accordingly. Even on a rare violation like 172.322(c), ensure your carrier knows it happened so they can document it and prevent future citations on the same route or cargo type.
