FMCSR 172.519: Placard Specifications — Driver Q&A

No. Across our inspection records, 172.519 citations result in an out-of-service order only 5.0% of the time—far below the 31.4% all-FMCSR average. Of 422 all-time citations in our database, just 21 resulted in OOS placement. This code is not OOS-eligible under FMCSA rules, so enforcement is discretionary. Most drivers receive a citation and are permitted to continue, though you must correct the placard defect before your next haul of hazmat.

FMCSR 172.519 covers placards that do not meet specifications—meaning your hazmat placards are damaged, faded, wrong size, wrong color, missing required text, or not mounted to specs. You must replace or repair the placard to match DOT standards: correct size (10¾" × 10¾"), legible text, proper mounting on all four sides of the vehicle, and no deterioration. Check the label on each placard and compare against the HAZMAT placard table in 49 CFR Part 172, Subpart F.

1. Inspect all placards on your vehicle for damage, fading, or missing text. Replace any that don't meet 10¾" × 10¾" spec or are visibly worn.
2. Document the repair with photos showing new, compliant placards installed.
3. Review the citation for the specific defect cited (e.g., "faded corner", "incorrect size").
4. Check for co-occurring violations: our data shows placard defects often appear alongside lamp issues (393.9) and windshield problems (393.78). Inspect those systems too.
5. If contesting, file a DataQs challenge within 90 days if you believe the inspection was factually wrong (e.g., placard was compliant when cited).

172.519 is relatively minor. Our database shows peer violations have vastly higher out-of-service rates: general loading/unloading hazmat (177.834A-HMC) hits 99.2% OOS; placarding violations (177.817A) hit 75.1% OOS. By contrast, 172.519's 5.0% OOS rate puts it near other specification-only codes like 172.516(c)(6) at 1.6% OOS. You're cited for the placard's condition or format, not for transporting hazmat unsafely, so enforcement is lenient.

Citation volume has been steady but low. Last 12 months: 91 citations nationwide. Monthly average runs 7–10 citations. Last 90 days: 21 citations. The trend shows no spike—most months hold 6–10 citations, though June 2025 was an outlier with 10 citations and 5 OOS orders (the highest single month). Overall, this is a low-frequency violation, ranking #978 of 3,036 FMCSR codes by citation count across all-time data.

Texas dominates enforcement. In the last 180 days, Texas had 41 citations with a 2.4% OOS rate. Iowa had 1 citation (0.0% OOS). Texas accounts for the vast majority of 172.519 citations in our records. If you operate hazmat through Texas, verify all placards meet spec before crossing state lines. Texas inspection stations are clearly focused on placard compliance in the hazmat category.

Yes. DataQs is FMCSA's official challenge portal for roadside inspection records. You have 90 days from the citation date to file. For 172.519, challenge success depends on factual evidence: if you have timestamped photos showing the placard was compliant (correct size, legible, undamaged) when cited, that's a strong DataQs case. If the defect was real (e.g., faded text, cracked corner), the citation will likely stand. Document any repairs you made after citation as evidence of good faith.

Bear Cartage & Intermodal Inc (USDOT 569614) has the most citations: 9 all-time. Five carriers tie at 5 citations each: TransCargo Loadgistics, Trareysa SA de CV, AKNA Transportes, Greenwood Motor Lines, and Luis Basilio Mendoza Gollas. On the vehicle side, Freightliners lead with 73 citations; other makes (63), Kenworths (48), and Peterbilts (35) follow. If you drive a Freightliner or other high-citation model, prioritize pre-trip placard checks.
