What 393.130 means in plain language
FMCSR 393.130 covers the proper securement of heavy vehicles, equipment, and machinery loaded onto a commercial motor vehicle. The rule exists because unsecured or under-secured heavy equipment shifts under braking and cornering forces, creating catastrophic risks for every vehicle on the road around you.
The core obligation is straightforward: any heavy piece of equipment or machinery riding on your trailer or flatbed must be held down in a way that keeps it from moving in any direction — forward, rearward, sideways, and vertically. That means the right number of tie-downs with the correct working load limit, applied at the correct points, with chains, straps, or binders that are in serviceable condition.
Inspectors look at this hard. They check whether the equipment itself has proper anchor points engaged, whether the tie-downs are rated for the load, whether there's any visible slack or damage, and whether the total securement system matches what the weight and dimensions of the load actually demand.
What our enforcement data actually shows
If you were cited for 393.130 today, the numbers are not in your favor. Across our database of 13 million+ inspections, this code carries a 97.7% out-of-service rate — meaning that in 6,371 out of 6,520 all-time citations, the driver was placed out of service on the spot. Only 149 inspections with this violation did not result in an OOS order.
To put that in context: the all-FMCSR average OOS rate across all codes in our database is 31.4%. The 393.130 rate of 97.7% is more than three times that average. Inspectors who see this violation almost universally decide the truck cannot move until the problem is fixed.
In terms of volume, our inspection records show 6,520 all-time citations for 393.130, placing it at #298 out of 3,036 FMCSR codes by citation count — not the most common code, but far from obscure. In the last 12 months alone, the data shows 1,068 citations, and 173 citations in just the last 90 days. Enforcement activity is consistent and active.
Looking at the monthly trend in our database, citation counts in recent months have ranged from 60 in February 2026 to 124 in July 2025, with OOS orders following nearly every citation every single month. There is no month in the last year where enforcement softened meaningfully on this code.
Who gets cited most
In the last 180 days, Texas leads all states with 329 citations and a 97.0% OOS rate. North Carolina recorded 49 citations at a 91.8% OOS rate, and Iowa logged 48 citations — with a 100.0% OOS rate, meaning every single citation in Iowa during that period resulted in an out-of-service order. Illinois added 19 citations at a 94.7% rate. The gap between Iowa's 100.0% and North Carolina's 91.8% is worth noting — over 8 percentage points — suggesting some variation in how inspectors exercise discretion, but the practical takeaway is that in every one of these states, getting cited almost certainly means you're not moving.
On the carrier side, our data shows fleets such as United Rentals North America Inc (USDOT 899748) with 32 all-time citations and EquipmentShare.com Inc (USDOT 2834104) with 19 citations appearing at the top of the citation counts. The pattern across the top-cited carriers is consistent with the nature of the code: companies regularly moving heavy equipment — rental fleets, construction support, and specialty haulers — accumulate exposure simply by the volume of loads they move.
How severe is this compared to similar codes
To understand where 393.130 sits in the enforcement landscape, compare it to a few peer codes in the Vehicle Maintenance category. The most-cited code in the category, 393.9(a) for inoperable required lamps, has 660,737 citations in our database — roughly 101 times the volume of 393.130 — but an OOS rate of only 15.4%. Inspectors cite lamp violations constantly but let most drivers keep moving. With 393.130, the inverse is true: citations are relatively rare but almost universally result in an OOS order.
Look at 396.3(a)(1), inspection/repair/maintenance general, which shows 236,919 citations and a 45.3% OOS rate. That's a much higher-volume code with a rate less than half of 393.130's 97.7%. Even that code, which covers broad maintenance failures, doesn't come close to the near-automatic shutdown that heavy equipment securement violations trigger.
The difference comes down to immediate safety consequence. Inspectors are trained to treat an unsecured piece of heavy equipment as an imminent hazard, and the data in our database confirms they act accordingly every time.
How to avoid it
The co-occurring violation data from our inspection records reveals important patterns. In the last 90 days, 393.130 citations appeared alongside 396.17C (no proof of periodic inspection) in 54 shared inspections and alongside 393.95A (missing or defective fire extinguisher) in 35 shared inspections. That combination suggests inspectors who find a securement problem then conduct a thorough inspection and find additional paperwork and equipment compliance gaps. One problem opens the door to many more.
Here are concrete pre-trip actions that address the full pattern:
- Verify every tie-down before departure. Check that all chains, straps, and binders are properly rated for the load weight, show no visible damage or fraying, and have no slack. Count the tie-downs against the load weight — more weight means more tie-downs.
- Confirm anchor points are engaged on the equipment itself. Tie-downs attached to non-structural parts of machinery can pass a visual glance but fail under load. Know where the manufacturer-designated tie-down points are.
- Check your fire extinguisher and emergency equipment. Our data shows 35 co-occurring citations for 393.95A and 28 for 393.95F in the last 90 days alone. If your securement gets flagged, inspectors will check everything else too.
- Have your periodic inspection documentation in the cab. 396.17C appeared alongside 393.130 in 54 shared inspections in the last 90 days. A missing inspection record compounds your violation exposure significantly.
- Check lamps and turn signals before you roll. 393.9 (inoperable required lamp) and 393.9TS (inoperative turn signal) each co-occurred with 393.130 in 54 and 21 shared inspections respectively. A burned lamp on a heavy equipment hauler signals to an inspector that attention to detail is lacking across the board.
- If you're operating a flatbed or lowboy, walk the load again after the first 50 miles. Equipment settles and tie-downs can lose tension. A stop-and-check is far cheaper than an OOS order 200 miles from your destination.
