What 172.514A means in plain language
When you transport hazardous materials in bulk form, federal regulations require you to display specific placards on your vehicle. These placards identify the class and hazard level of the material you're carrying so emergency responders and other road users know what they're dealing with if something goes wrong.
A citation under 172.514A means you offered to transport a bulk hazmat package—or actually transported it—without the required placard in place. This isn't about missing one placard in a stack of many; it's about the bulk container itself not being properly marked. The placard is a square diamond-shaped sign that must be visible, legible, and positioned according to federal spec. If it's missing, obscured, or never was affixed, you're in violation.
This is a serious compliance issue because placarding is how you communicate hazard information before an accident happens. Without it, you're putting responders and the public at unnecessary risk—and you're breaking federal law.
What our enforcement data actually shows
Across our 13 million+ inspection records, 172.514A has been cited 41 times since tracking began, with 30 citations in the last 12 months and 6 in the last 90 days. This makes it the 1,687th most frequently cited FMCSR code out of 3,036 codes overall.
What matters most: the out-of-service rate. Our data shows 25 of the 41 all-time citations (61.0%) resulted in the vehicle being placed out of service. That's significantly higher than the all-FMCSR average OOS rate of 31.4%. When you're cited for this violation, you face roughly a two-in-three chance your truck will be taken out of service on the spot.
The trend over the past year shows enforcement is inconsistent but serious when it occurs. We recorded 1 citation in April 2025, peaked at 5 citations in August 2025 and December 2025, and dipped to 1 in January 2026. This pattern suggests inspectors are catching it opportunistically rather than through systematic sweeps, but when they do, the OOS consequence is highly likely.
Who gets cited most
Our inspection records show that Texas accounts for 14 of the citations in the last 180 days, with an OOS rate of 57.1%—slightly lower than the overall 61.0% but still a strong indicator of enforcement severity in that state.
When we look at carriers in our database, ECO TRANSPORTES INTERNACIONALES SA DE CV (USDOT 558117) appears most frequently with 4 citations, followed by ADRIAN IVES PORTALES AGUILAR (USDOT 2456389) and FERROSRB SA DE CV (USDOT 4027419), each with 2 citations. The fact that carriers handling bulk hazmat operations show repeated citations underscores how critical proper placard management is to your compliance profile.
How severe is this compared to similar codes
To understand where 172.514A sits in the hierarchy of hazmat violations, consider these peer codes in the same category:
177.817(a) — Placarding violation has been cited 2,274 times with a 75.1% OOS rate. That's a much larger population and a higher OOS rate, suggesting broader placarding failures are treated even more severely.
172.502(a)(1) — Placarding general requirements has 1,820 citations with an 18.5% OOS rate. This is a lower-severity placarding code, indicating that if your violation is framed as a general requirement miss rather than a bulk-package-specific failure, the enforcement outcome could be less severe.
172.516(c)(6) — Placard damaged deteriorated or obscured has 1,796 citations but only a 1.6% OOS rate. This tells us that if your placard was present but damaged or obscured rather than completely absent, inspectors are much more likely to issue a citation without pulling you from service.
The distinction matters: 172.514A is about a bulk package without proper placard at all, and the 61.0% OOS rate reflects the seriousness inspectors attach to that complete absence.
How to avoid it
Based on the violations we see co-occurring with 172.514A in the same inspections, here are your action items:
-
Before every trip, verify placard presence and condition on your bulk tank or container. Our data shows placarding violations (177.817A) frequently appear alongside 172.514A. Don't assume the placard is there because the truck was compliant last week. Check it every time you take the wheel.
-
Inspect the placard for readability and horizontal alignment. We found co-occurring citations for placard-not-reading-horizontally (172.516C5) and placard-specification failures (172.519). A placard that's at an angle, faded, or torn might pass your eyes but fail inspection. If it doesn't look crisp and level, replace it.
-
If you haul different bulk materials, label the right hazmat class before departure. One co-occurring violation (172.332A) involved missing hazmat class or division ID numbers. Confirm the placard matches the cargo you're carrying. Swapping loads without updating placards is a guaranteed citation.
-
Ensure emergency response information is accessible and maintained. We see 172.602C1 co-occur with 172.514A inspections. Your shipping papers and emergency response guide should be within arm's reach during the trip, not buried under seat cushions or in a locked compartment.
-
Walk around your vehicle at rest stops. Placards can be knocked loose by weather, carwash equipment, or contact with dock structures. A 30-second visual check mid-route could save you from a roadside citation and OOS order.
The stakes are clear: 61% of drivers cited for this violation see their vehicles taken out of service. That's downtime, lost revenue, and a mark on your safety record. The placard is not optional—it's your first line of communication about what you're hauling. Make it non-negotiable in your pre-trip routine.
