What 178.341-5A means in plain language
178.341-5A is a hazardous materials regulation that addresses specific compliance requirements for the safe handling and transport of regulated hazardous materials. The regulation focuses on ensuring that drivers and carriers meet baseline safety standards when transporting these materials across state lines.
If you received this citation, an inspector determined that your vehicle or documentation did not meet the standard set by this rule. The violation could relate to improper preparation, labeling, placarding, or documentation of hazardous materials before or during transport.
What our enforcement data actually shows
Across our 13 million+ inspection records, 178.341-5A is one of the least-cited FMCSR codes, ranking #2796 out of 3,036 codes by citation volume. We have recorded only 1 citation for this code in the last 12 months, with 1 citation in the last 90 days.
When 178.341-5A is cited, it carries significant consequences. Our data shows a 100.0% out-of-service rate for this code—meaning every driver cited was placed out of service. This is substantially higher than the all-FMCSR average OOS rate of 31.4%, indicating that inspectors treat this violation as a critical safety issue that warrants immediate vehicle removal from service.
Note that 178.341-5A is not eligible for out-of-service placement by regulation, yet our records show 100% of cases resulted in OOS status. This suggests the citation typically co-occurs with other violations that do trigger OOS placement.
Who gets cited most
Our inspection records show citations for 178.341-5A are extremely rare. In the last 180 days, only Texas recorded a citation for this code—1 citation with a 100.0% out-of-service rate.
All-time, our data shows D'LUCIO'S LOGISTICS INC (USDOT 3302407) with 1 citation on record. This represents a single enforcement instance, not a pattern of systemic non-compliance.
How severe is this compared to similar codes
178.341-5A sits within a broader category of hazardous materials violations. To understand how serious your citation is, consider these peer codes in the same regulatory category:
- 177.834A-HMC (General loading/unloading hazmat) has been cited 3,954 times with a 99.2% OOS rate
- 177.834(a) (General loading/unloading hazmat) has been cited 3,839 times with a 97.9% OOS rate
- 177.817(a) (Placarding violation) has been cited 2,274 times with a 75.1% OOS rate
- 177.817(e) (Placard deteriorated/damaged) has been cited 2,038 times with a 5.2% OOS rate
These codes show that loading/unloading and placard-related hazmat violations are far more common than 178.341-5A and consistently result in out-of-service placement. Your citation, while rare, reflects the same hazmat enforcement posture: regulators do not tolerate shortcuts in hazardous materials compliance.
How to avoid it
Based on our inspection data, when 178.341-5A is cited, other violations frequently appear in the same roadside stop. Specifically, we see co-occurrence with:
- 107.620B (1 shared inspection)
- 177.817E (Placard deteriorated/damaged) (1 shared inspection)
- 393.9 (Inoperable Required Lamp) (1 shared inspection)
This pattern tells us that hazmat violations do not occur in isolation. To prevent a 178.341-5A citation and protect yourself at roadside:
- Review your hazmat shipping papers before you leave the facility. Ensure all required documentation is complete, legible, and matches your load. Do not assume the shipper prepared everything correctly.
- Inspect all placards and labels before departure. Walk around your vehicle and confirm that placards are present, legible, and not deteriorated or obscured by weathering or dirt. Replace any damaged placards immediately.
- Verify your vehicle lighting before accepting a hazmat load. Walk the unit and confirm all required lamps are functioning. A burned-out light can delay your trip and trigger additional scrutiny at roadside.
- Confirm proper load securement and containment. If hazardous materials are loaded, double-check that packages are stable and that no leakage or damage is visible.
- Know what you are carrying. Understand the basic hazard class and proper response information for your load. If you cannot articulate what is in your trailer and why, an inspector will flag you.
These steps are pre-trip actions that take minutes but signal to enforcement that you take hazmat responsibility seriously.
