What 180.336 means in plain language
180.336 falls under the hazardous materials regulations and relates to specific requirements for transporting or handling hazardous cargo. The regulation prescribes what drivers and carriers must do to ensure hazmat shipments are managed safely and in compliance with Department of Transportation rules.
If you were cited for this code, an inspector found a deficiency in how your vehicle, cargo, or documentation met the hazmat standards set out in this regulation. This could involve packaging, labeling, placarding, documentation, or operational procedures tied to hazardous materials.
What our enforcement data actually shows
Across 13 million inspections in our database, 180.336 has generated only 1 citation all-time and 1 citation in the last 12 months. In the last 90 days, we recorded 0 citations. This makes 180.336 the #2796th most-cited FMCSR code out of 3,036 total codes—extremely rare in roadside enforcement.
None of the 1 citation resulted in an out-of-service order, giving this code a 0.0% out-of-service rate. For context, the all-FMCSR average OOS rate is 31.4%, meaning 180.336 violations are almost never deemed severe enough to remove a vehicle from service immediately. This suggests that when the citation is issued, inspectors typically view the deficiency as correctable or non-critical to roadworthiness.
Who gets cited most
Our inspection records show only 1 citation for 180.336 in our entire 13-million-record database. PC TRANSPORT INC (USDOT 191414) received that citation. The lack of multiple citations across states or carriers underscores how infrequently this code is enforced at the roadside.
How severe is this compared to similar codes
Within the hazardous materials category, 180.336 sits at the lenient end of enforcement severity. Compare it to peer violations:
- 177.834A-HMC (General loading/unloading hazmat) has 3,954 citations with a 99.2% OOS rate—meaning almost every citation results in an out-of-service order.
- 177.834(a) (General loading/unloading hazmat) has 3,839 citations with a 97.9% OOS rate.
- 177.817(a) (Placarding violation) has 2,274 citations with a 75.1% OOS rate.
By contrast, 180.336's 0.0% OOS rate reflects a dramatically different enforcement pattern. It is treated far less seriously than major hazmat violations but sits in a hazmat category, which distinguishes it from general vehicle or driver defects.
How to avoid it
Because 180.336 is so rarely cited, specific co-occurrence patterns in our data are limited. However, you can reduce risk by:
- Review your hazmat certification. Ensure your HME (Hazardous Materials Endorsement) is current and that you understand the specific commodity you were hauling when cited.
- Double-check placarding and labeling. Even minor hazmat shipments require correct placards and labels. Inspect them before accepting the load and again at roadside inspection.
- Verify shipping papers match cargo. Have accurate, legible hazardous materials documentation in the cab. Mismatches between paperwork and actual load are common citation triggers.
- Know your vehicle's hazmat compartment. If your truck was used for multiple hazmat runs, ensure tanks, containers, or cargo areas are properly cleaned, sealed, and marked for their intended use.
- Pre-trip inspection focus. Walk around your vehicle during pre-trip. Look for damaged placards, leaks, loose cargo, or missing or obscured labels that could trigger a hazmat citation.
Given how rare this citation is, your inspector likely found a very specific technical discrepancy rather than a safety-critical failure. Work with your carrier's safety manager to understand exactly what was noted and correct it before your next shipment.
