What 393.106A means in plain language
When you load cargo onto your truck, the front end of your load needs protection. That's where the headerboard or bulkhead comes in—a barrier at the front of your cargo area that keeps freight from sliding forward into the cab during braking, turns, or sudden stops.
Code 393.106A requires that headerboard or bulkhead to be in place and in good condition whenever the load actually needs one. "Inadequate" means it's damaged, weakened, has gaps, or doesn't meet strength requirements for the cargo weight. "Missing" means it's not there at all when it should be. Either way, the inspector will cite you.
The regulation covers both active securement (the physical barrier) and the structural integrity of what's already on your truck. If you're hauling freight that could shift forward—grain, steel, pallets, or other heavy goods—your front-end structure has to stop it.
What our enforcement data actually shows
Across our 13 million inspection records, 393.106A is relatively rare: only 8 all-time citations in our database, with 7 in the last 12 months and 2 in the last 90 days. It ranks #2269 out of 3,036 FMCSR codes by citation volume.
Despite low frequency, the consequence rate is significant. Out of 8 all-time citations, 3 resulted in out-of-service orders—a 37.5% OOS rate. That's above the all-FMCSR average of 31.4%, meaning when inspectors find this violation, they're more likely to ground your truck than they are for the typical maintenance code.
In the last 90 days, we've seen 2 citations with 1 out-of-service placement. Monthly enforcement has been light but consistent; June 2025 and December 2025 each saw 2 citations, while January 2026 had 1.
Who gets cited most
Texas dominates the citation pattern. Over the last 180 days, Texas accounts for 5 citations out of the small national total, with an out-of-service rate of 40.0%—notably higher than the national average for this code.
Our data shows individual operators and small fleets cited under 393.106A, including carriers like TRANSPORTES DE CARGA SAUL SALINAS SA DE CV, FJR TRUCKING SERVICES, and SMITH TRACTOR & EQUIPMENT INC, each with 1 citation in our all-time records. No single carrier shows a pattern of repeat citations for this specific violation.
How severe is this compared to similar codes
In the vehicle maintenance category, 393.106A sits in the middle ground for severity. Compare it to related cargo-securement and brake codes:
393.9 (Inoperable required lamps) has 660,737 citations with only a 15.4% OOS rate—much more common but less likely to result in removal from service. 396.3(a)(1) (Inspection/repair/maintenance - general) shows 236,919 citations with a 45.3% OOS rate, indicating inspection-violation patterns trigger out-of-service action more readily. 393.47E (Slack adjuster defective), which co-occurs with 393.106A in our data, has 180,363 citations but a 0.0% OOS rate, suggesting brake-adjustment issues are cited but rarely grounds for immediate removal.
The 37.5% OOS rate for 393.106A reflects inspector concern: a compromised front-end structure poses genuine safety risk, especially on loaded trucks at highway speed.
How to avoid it
Before you load:
- Walk the entire front of your cargo area before loading. Look for cracks, dents, missing bolts, or gaps in the headerboard. If it's damaged, report it to dispatch and request a replacement or repair before accepting freight.
- Verify the headerboard or bulkhead is the right height and strength for the cargo type and weight you're about to carry. Light loads may not require a full barrier; heavy, shiftable loads do.
- Check that all fasteners—bolts, welds, brackets—securing the front barrier are tight and intact. A loose headerboard can fail under load.
During pre-trip:
- Include the front barrier in your daily vehicle walk-around. It's as critical as tires, lights, and brakes because cargo shift causes collisions and rollovers.
- On trucks with multiple loads throughout the day, reinspect after each unload. Pallets, strapping, and structural contact can weaken the barrier.
- If you notice co-occurring maintenance issues—slack adjusters (393.47E) or steering components (393.53B) that are worn—address those too. Our data shows these violations frequently appear together in the same inspection, signaling broader pre-trip gaps.
Documentation:
- Keep a photo log of your headerboard condition at the start of each week. If cited, you have evidence of intent to comply.
- Note any repair requests for barriers in your vehicle maintenance log with dates. Show the inspector your compliance history.
The bottom line: a 37.5% out-of-service rate means this citation carries real teeth. Inspectors won't hesitate to ground your truck if the front barrier is questionable, so treat it like a safety system, not an afterthought.
