What 177.842B means in plain language
177.842B is a hazardous materials regulation that falls under the broader framework of how hazmat shipments must be handled, loaded, and transported. The rule establishes specific requirements for the proper management of hazardous cargo in compliance with Department of Transportation standards.
If you received this citation at roadside, an inspector determined that your vehicle or cargo handling did not meet the standard outlined in this code. This could relate to how the load was secured, positioned, or managed during transport or at a stop. The citation is telling you that something about the way the hazmat was being carried or handled didn't meet federal expectations.
What our enforcement data actually shows
Across our 13 million+ inspection records, 177.842B is rarely cited. We have recorded exactly 1 citation for this code in our entire database, which occurred in August 2025. In the last 90 days, we see zero citations. This makes 177.842B ranked #2,796 out of 3,036 FMCSR codes by citation volume—meaning it's one of the least-cited hazmat violations in roadside enforcement.
The out-of-service rate for 177.842B stands at 0.0%: the one citation on record did not result in an out-of-service order. For context, the all-FMCSR average out-of-service rate is 31.4%, so this code is well below that baseline. That said, the extremely low enforcement volume means caution about extrapolating national patterns from a single citation.
Who gets cited most
Our data is limited by the low citation count. We have one recorded citation under this code, attributed to Alpha Testing LLC (USDOT 432419) in August 2025, and it involved a RAM vehicle. Because the enforcement volume is so sparse, we cannot reliably report state-level or carrier-level trends for this violation.
How severe is this compared to similar codes
Placing 177.842B in context with other hazmat violations reveals a stark difference in enforcement intensity. Consider these peer codes in the hazardous materials category:
- 177.834A (general loading/unloading hazmat) has 3,954 citations with a 99.2% out-of-service rate—one of the most aggressively enforced hazmat rules.
- 177.834(a) (also general loading/unloading hazmat) shows 3,839 citations and a 97.9% OOS rate.
- 177.817(a) (placarding violation) has 2,274 citations and a 75.1% OOS rate.
In comparison, 177.842B has generated just 1 citation with 0.0% OOS. This suggests that either the violation is extremely rare in practice, or it is enforced in ways that do not typically lead to removal from service. Most hazmat-category violations carry much higher enforcement volume and severity.
How to avoid it
Because this code is so rarely cited, concrete guidance is limited by available data. However, these best practices apply broadly to hazmat transport and should reduce risk:
- Verify your hazmat load is properly secured before every trip. Check that containers, drums, or packages cannot shift, tip, or move during transit. Ensure all tie-downs, straps, or blocking are rated and installed correctly.
- Confirm placarding and labeling are visible, undamaged, and affixed to the correct sides of your vehicle. Hazmat placards must be readable and meet size and color standards.
- Review your bill of lading and shipping papers against the actual cargo in your truck. Misclassification or misdeclared hazmat is a serious compliance gap.
- Inspect your vehicle's condition before accepting a hazmat load. A RAM truck—the only vehicle type in our citation record—should be checked for leaks, cracks, or structural issues that could compromise cargo containment.
- Know the specific DOT class of your load and the handling requirements that apply. Different hazmat classes have different rules for segregation, temperature control, and emergency response information.
- Keep your Emergency Response Guidebook (ERG) accessible and familiarize yourself with the hazmat you are carrying. In an emergency or during inspection, you must be able to provide accurate information about the material.
Because this violation is infrequently cited, focus on the fundamentals of hazmat safety: secure, properly documented, and correctly placarded loads handled with the care the regulations demand.
