What 376.11D1 means in plain language
376.11D1 relates to hazardous materials transportation and carrier responsibilities. The regulation establishes requirements for how motor carriers must handle and transport certain hazardous commodities, including documentation, labeling, and vehicle preparation. When an inspector cites you for 376.11D1, they've determined that your carrier, vehicle, or documentation didn't meet these standards at the moment of inspection.
This is a carrier-level violation in many cases—meaning your fleet's policies and training are under review, not just your individual actions. However, as the driver, you may have been cited because your vehicle lacked proper placarding, your hazmat papers were incomplete or inaccurate, or the load wasn't secured or prepared according to hazmat rules.
What our enforcement data actually shows
Across our 13 million+ roadside inspection records, 376.11D1 has generated 1,258 citations all-time, with 143 citations in the last 12 months and 23 in the last 90 days. This ranks the code #661 out of 3,036 FMCSR violations by citation volume—a mid-range violation, not rare but far from the most common.
The critical number: 0.0% out-of-service rate. None of the 1,258 drivers or vehicles cited for 376.11D1 in our database were placed out of service. This is substantially lower than the all-FMCSR average of 31.4% OOS rate, meaning inspectors treat this violation as correctable without immediate roadside removal. You will likely receive a citation and warning, but not an immediate shutdown.
In the last 90 days, enforcement has been steady but light: May and June 2025 each saw 29 citations, but recent months (April 2026) show only 3 citations, suggesting spotty enforcement depending on inspector focus and your region.
Who gets cited most
Our inspection records show citations concentrated in three states over the last 180 days:
- Illinois: 30 citations, 0.0% OOS rate
- North Carolina: 12 citations, 0.0% OOS rate
- New Mexico: 1 citation, 0.0% OOS rate
All three maintain a 0.0% out-of-service rate, meaning state-level enforcement patterns are consistent: this violation is cited but not used as grounds for immediate vehicle removal.
Large carriers such as Penske Truck Leasing Co LP (10 citations all-time) and Ryder Truck Rental Inc (8 citations) appear in our data, but citation volume likely reflects fleet size and exposure rather than systemic non-compliance. Smaller and dedicated carriers also appear, indicating the violation spans operations of all sizes.
How severe is this compared to similar codes
Within the same regulatory category, 376.11D1 sits alongside peer codes with notably different enforcement patterns:
- 376.11(d)(1) (the parent regulation): 6,383 citations, 0.0% OOS rate—far more frequent but equally unlikely to result in OOS placement.
- 107.620(b): 2,120 citations, 0.2% OOS rate—nearly double the citation count but still very low OOS rate.
- 999 (miscellaneous): 4,802 citations, 12.1% OOS rate—more frequently cited and 12× more likely to trigger out-of-service action.
By comparison, 376.11D1 is moderately cited and carries almost no risk of immediate removal. Inspectors view it as a documentation or procedural error rather than an immediate safety hazard.
How to avoid it
Our data reveals which violations co-occur with 376.11D1 in the same inspection, pointing to root causes:
1. Verify hazmat training and documentation before departure
- 7 of 23 recent 376.11D1 citations also included 392.2RG (operating while ill or fatigued). Fatigue impairs attention to detail; ensure you're rested before any hazmat haul.
- Run through your shipping papers at pre-trip. Match product names, UN numbers, proper shipping names, and hazard class labels to your actual load.
- Confirm your hazmat endorsement is current and that your carrier's training records are up to date.
2. Check placarding and vehicle condition
- 5 co-occurring citations involved 393.9 (inoperable required lamps). Hazmat vehicles must have functioning lights; dark or failed lamps invite secondary inspection and increase citation risk.
- Verify placards are correct, legible, and displayed on all four sides if required.
- 3 co-occurrences involved 393.78 (windshield defects). A cracked or obstructed windshield reduces your ability to see hazmat placards on other vehicles and signals poor vehicle maintenance to inspectors.
3. Load security and preparation
- Freightliner and International trucks (381 and 255 citations respectively in our all-time data) dominate 376.11D1 enforcement, suggesting these popular heavy haulers are frequently carrying hazmat. If you drive one, assume extra scrutiny.
- Secure all hazmat containers before rolling. Shifting loads can trigger secondary inspection.
4. Electronic logging device (ELD) compliance
- 3 co-occurrences involved 395.8A-ELD (failing to keep RODS). Gaps or false entries in your hours-of-service logs invite detailed vehicle and cargo inspection.
- Keep clean ELD records; they're often the first thing inspectors check and influence how thoroughly they examine your load.
5. Honesty and accuracy on manifests
- 3 co-occurrences involved 390.35 (making false entries). Never guess or approximate hazmat information. A single error in weight, UN number, or hazard class can trigger a 376.11D1 citation and compound your liability.
- Have your hazmat shipper double-check paperwork before you accept the load.
Since your citation carried zero risk of immediate out-of-service placement, your next steps are to work with your fleet's safety manager to understand which specific element (documentation, placarding, training, or vehicle condition) triggered the citation, correct it, and ensure you and your company are prepared for the follow-up inspection or audit.
