What 393.112 means in plain language
When you receive a citation for 393.112, it means a roadside inspector found that your tiedown equipment—the straps, chains, or other devices securing cargo—is not adjustable by you, the driver, during normal operation.
This regulation exists because you need the ability to tighten, loosen, or adjust cargo securement while on the road. If your tiedown system is permanently fixed or designed in a way that prevents driver adjustment, it creates a safety gap. Cargo can shift during transit, and you should have the immediate capability to secure it without waiting for maintenance or specialized tools.
The issue is typically found on vehicles where the attachment points, ratcheting mechanisms, or anchor systems lack proper adjustability. It's not about whether you did adjust them on a given trip—it's whether the equipment allows you to adjust them if needed.
What our enforcement data actually shows
Across our 13 million+ roadside inspection records, 393.112 has generated 878 all-time citations, ranking it #748 out of 3,036 FMCSR codes by enforcement volume. In the last 12 months, inspectors cited this violation 77 times nationally, with 17 citations in the most recent 90-day period.
The out-of-service rate for 393.112 is exceptionally low at 0.6%—only 5 vehicles out of 873 citations resulted in an out-of-service order all-time. This means that in the vast majority of cases (873 out of 878), inspectors issued a citation but allowed you to continue operating. By contrast, the all-FMCSR average out-of-service rate stands at 31.4%, making 393.112 one of the least severe violations from an immediate roadside enforcement perspective.
The citation rate has remained relatively modest across the past year. Our data shows August 2025 was the peak month with 13 citations, while other months ranged from 1 to 10 citations. This pattern suggests the violation is situational rather than systemic across the industry.
Who gets cited most
Our inspection records show the geographic distribution of 393.112 citations is concentrated. Over the last 180 days, Texas led with 27 citations, followed by Iowa with 6 citations. Both states maintained a 0.0% out-of-service rate, meaning no citations resulted in immediate removal from service.
By carrier, our data shows fleets such as Javier Malagon (USDOT 2456296) with 5 all-time citations and Tow 2 Tow Wrecker Service LLC (USDOT 3176350) with 4 citations. These represent the highest citation counts in our database for this code. The distribution across carriers is relatively even, with no single operator accounting for a disproportionate share, suggesting this is not a fleet-specific problem but rather an equipment or inspection-protocol issue.
How severe is this compared to similar codes
Within the Vehicle Maintenance category, 393.112 is among the least-cited violations. For context, inspect the peer codes:
- 393.9 (Inoperable required lamps): 180,097 all-time citations with a 6.9% out-of-service rate—roughly 200 times more frequently cited than 393.112, and with a significantly higher OOS rate.
- 393.11 (Lighting devices/reflectors): 179,734 all-time citations at a 1.8% out-of-service rate—also substantially more common, though still lower OOS impact.
- 396.3(a)(1) (Inspection/repair/maintenance - general): 236,919 citations with a 45.3% out-of-service rate—far more severe in both frequency and immediate enforcement consequences.
The 393.112 data pattern suggests inspectors treat it as a correctable deficiency rather than an acute safety risk. Most operators receive a citation and are sent on their way, giving you an opportunity to address the issue.
How to avoid it
Your prevention strategy should focus on two areas: equipment inspection and understanding what "adjustable by driver" actually means in practice.
Before you depart:
- Test all tiedown mechanisms personally. Don't assume the previous driver left them functional. Grab each strap, chain, or ratchet handle and move it through its full range of motion. If it doesn't move, or requires tools you don't carry, that's a red flag.
- Inspect anchor points for rust or damage. Corrosion can freeze ratcheting systems. If a tiedown won't move freely, report it to your carrier or maintenance team before rolling.
- Check that ratchet handles pivot freely. Many 393.112 citations occur when ratchet handles are bent, welded, or otherwise locked in place. You should be able to operate each one with one hand in normal use.
- Verify your cargo doesn't cover or block access to tiedown hardware. If you can't physically reach the adjustment mechanism once loaded, you can't adjust it—and that will be cited.
Relationship to common roadside findings:
Our inspection data shows 393.112 often appears alongside cargo securement issues like 393.128 (cargo securement - roll-on/roll-off containers) and 393.130 (cargo securement - heavy equipment), as well as general maintenance codes like 393.55C2 (coupling device/towing methods defective). This pattern suggests that when cargo systems are neglected, multiple securement and attachment issues emerge. A rigorous pre-trip inspection of all securing hardware—not just the straps, but the anchor points, attachment brackets, and adjustment mechanisms—will catch most of these together.
Vehicle-specific note:
Our citation data shows Ford vehicles account for 104 of the 878 all-time 393.112 citations, followed by Freightliner (36 citations) and International (32 citations). If you operate one of these common makes, pay extra attention to the tiedown systems as delivered by the manufacturer—some older or high-mileage units may have design quirks or wear patterns that reduce adjustability. Proactive maintenance and replacement of worn components will reduce your risk.
The bottom line: this citation is avoidable through disciplined pre-trip inspection and immediate reporting of any tiedown adjustment issues to your dispatcher or maintenance team.
