What 393.130C means in plain language
FMCSR 393.130C addresses the secure fastening of heavy vehicles, equipment, and machinery on your truck. This isn't about loose pallets or general freight—it applies to substantial items like construction equipment, industrial machinery, or other heavy loads that require specific securement methods to prevent movement during transit.
Inspectors check that your cargo is properly restrained using appropriate securement devices: chains, straps, binders, or other methods rated for the load weight and dynamics. The goal is simple: nothing shifts, slides, or falls off your truck while you're on the road. A citation means an inspector found that your heavy cargo lacked adequate securement.
This is a Vehicle Maintenance category violation, and it carries a CSA severity weight of 7—a mid-range severity marker that factors into your safety profile.
What our enforcement data actually shows
Across our 13 million+ inspection records, 393.130C is relatively uncommon. We've recorded 106 all-time citations, with 42 in the last 12 months and 10 in the last 90 days. Ranked #1403 of 3,036 FMCSR codes by citation volume, this violation sits well below the most frequently cited infractions.
However, the out-of-service rate tells a different story. Our inspection records show a 97.2% out-of-service rate for 393.130C—meaning nearly every citation results in the vehicle being placed out of service. This is strikingly high compared to the all-FMCSR average out-of-service rate of 31.4%. Inspectors treat improper cargo securement on heavy equipment as an immediate safety hazard; if you're cited, your truck is almost certainly coming off the road until the load is corrected.
That enforcement pattern has been consistent. In the last 12 months alone, 41 of 42 citations resulted in out-of-service orders. The data suggests that when this violation is detected, remediation is mandatory before the vehicle resumes operation.
Who gets cited most
Over the last 180 days, our data shows citations concentrated in four states: Iowa (4 citations, 100% out-of-service rate), Illinois (4 citations, 75% out-of-service rate), North Carolina (4 citations, 100% out-of-service rate), and New Mexico (4 citations, 100% out-of-service rate). The variation in OOS rates across these states reflects different enforcement postures or cargo mixes; North Carolina, Iowa, and New Mexico consistently placed all cited vehicles out of service, while Illinois had one citation that did not result in an out-of-service order.
Looking at carriers across all-time data, our inspection records show fleets such as Greatwide American Trans-Freight LLC with 2 citations and A B O Trans Inc with 2 citations—both modest frequency. No single carrier dominates 393.130C citations, suggesting this violation is distributed across many operators rather than concentrated in a few high-risk fleets.
Vehicle makes cited most frequently include Peterbilt (20 citations), Freightliner (13 citations), and Kenworth (12 citations). This pattern reflects the prevalence of heavy-duty tractors in cargo securement work; flatbeds, lowbeds, and heavy-haul equipment carriers rely on these chassis types, and they represent the majority of vehicles hauling the kinds of loads subject to this regulation.
How severe is this compared to similar codes
In the Vehicle Maintenance category, 393.130C sits at an extreme end of enforcement outcomes. Peer codes like 393.9(a) (Inoperable required lamps) has 660,737 citations with a 15.4% out-of-service rate, and 396.3(a)(1) (Inspection/repair/maintenance general) has 236,919 citations with a 45.3% out-of-service rate. Both are far more common but result in out-of-service orders much less frequently.
Even 393.78 (Windshield condition defective), another vehicle-condition code, shows 157,894 citations with only a 0.3% out-of-service rate. The contrast is stark: 393.130C's 97.2% out-of-service rate reflects inspector judgment that a cargo securement failure poses immediate risk to the driver, other road users, and the load itself. Regulators treat this violation as acutely hazardous, not a minor defect.
How to avoid it
Pre-trip cargo securement checklist:
- Inspect securement devices before loading. Check all chains, binders, straps, and fastening hardware for damage, corrosion, or wear. A compromised strap will fail under load dynamics.
- Match securement method to load weight and dimensions. Heavy vehicles and machinery aren't one-size-fits-all. Use chain or equivalent for industrial loads; verify working load limits exceed your cargo weight by a safe margin.
- Distribute load weight evenly on your trailer or truck bed. Uneven loading stresses securement on one side and increases shifting risk during turns or braking.
- Tighten all fasteners fully. Slack binders and loose straps migrate during transit. Audit tightness at every fuel stop, especially on longer runs.
- Account for dynamic forces. Cargo doesn't shift only vertically; it moves forward under braking, sideways during turns, and backward during acceleration. Use multiple securement points and cross-bracing for large equipment.
- Know your vehicle's rated capacity and tie-down points. Overloading or fastening to non-rated anchor points is a setup for failure. Review your truck's specifications and manufacturer guidance.
- Document your securement. Take photos or notes of how heavy equipment is secured before departure. It serves as evidence of your due diligence and helps you replicate proper technique on repeat hauls.
Our inspection records also show that 393.130C commonly co-occurs with brake, windshield, and operational violations (such as fatigue citations). This pattern suggests that cargo securement failures often occur alongside other maintenance lapses or driver condition issues. If you're hauling heavy equipment, treat pre-trip inspection as non-negotiable; it catches both securement and mechanical problems before an inspector does.
The 97.2% out-of-service rate is your real takeaway: this violation doesn't result in a warning or a minor fine. It stops your truck immediately. Invest time in learning your load and your securement gear; the cost of that effort is far smaller than the cost of an out-of-service citation.
