Freight container not placarded

Questions & Answers

Direct answers grounded in TruckCodex inspection data

Will 172.512A put my truck out of service?

No. Across our inspection database, 172.512A citations have resulted in a 0.0% out-of-service rate—meaning no trucks cited for this violation were placed out of service. For context, the national average OOS rate across all FMCSR codes is 31.4%, so this violation sits well below the enforcement threshold for immediate roadside removal.

How serious is 172.512A compared to other placard violations?

172.512A is substantially less serious than related hazmat placard violations. Our records show that 177.817(a) (general placarding violation) has a 75.1% OOS rate across 2,274 citations, while 172.516(c)(6) (placard damaged or obscured) shows a 1.6% OOS rate. 172.512A ranks #2796 out of 3,036 FMCSR codes by citation frequency, indicating it is a rare citation in the hazmat category.

Is 172.512A still being enforced in 2026?

Enforcement of this code is extremely rare. Our database shows only 1 citation all-time, with 0 citations in the last 12 months and 0 in the last 90 days. While the violation remains on the books, roadside inspectors are not currently citing it, suggesting either strict compliance across the industry or a shift in enforcement priorities toward higher-risk placarding violations.

What do I do immediately after getting cited for 172.512A?

First: Request a copy of the inspection report and citation from the inspector or state agency within 10 days. Second: Verify the specific freight container that was cited—confirm it matches your load documentation and shipping papers. Third: Document that placarding has been or will be corrected, and retain photos of the container with proper placards. Fourth: Keep all documentation for potential DataQs appeal or future disputes with your carrier.

Can I contest a 172.512A citation through DataQs?

Yes. If you believe the citation was issued in error—for example, if the container was placarded and the inspector missed it, or if the placard was applied correctly per the hazmat regulations—you can file a DataQs (Motor Carrier Management Services) appeal within 30 days of the citation. Provide photographic evidence or the shipping documentation showing compliance at the time of inspection. DocumentationErrors and equipment condition disputes are the strongest grounds for appeal.

Where do most 172.512A citations occur?

Given that our database shows only 1 citation all-time for 172.512A, geographic distribution data is not meaningful. The single citation on record was issued to a carrier with USDOT 2420517 (Eduardo Jimenez Marroquin). Rather than focusing on state trends, drivers should assume 172.512A compliance is expected nationwide wherever hazmat freight is being transported.

Does this violation follow me to my next job or stay with the carrier?

Hazmat placard violations are recorded against both the driver and the carrier under FMCSA's Safety Management System. Your driving record with the USDOT will reflect the citation; your new employer can see it in a Background Records Request (BRR). However, because the 0.0% OOS rate indicates minimal regulatory severity, a single 172.512A citation is unlikely to disqualify you from employment or significantly harm your CSA profile compared to major violations.
