What 393.126B means in plain language
Code 393.126B addresses the improper securing of flattened or crushed vehicles during transport. This applies primarily to carriers moving scrap metal, crushed auto bodies, compacted waste, or similar cargo that has already been compressed into dense blocks or sheets.
The regulation requires that these materials be properly restrained so they cannot shift, fall, or break loose during transit. Unlike general cargo securement rules that focus on preventing items from sliding within a trailer, 393.126B is specifically about keeping pre-flattened material—which may have sharp edges, irregular shapes, or unstable stacking—from moving in ways that create road hazards or damage the cargo itself.
If an inspector observes that your flattened or crushed cargo is not adequately tied down, braced, blocked, or otherwise restrained in a manner that prevents movement, they can issue a 393.126B citation at roadside.
What our enforcement data actually shows
Across our 13 million inspection records, 393.126B has been cited 143 times in total, with 89 citations in the last 12 months and 16 in the last 90 days. This ranks the code #1319 of 3,036 FMCSR codes by citation volume—it is a relatively uncommon violation.
What matters more than frequency, however, is severity. Our data shows a 74.1% out-of-service rate for this code, compared to the all-FMCSR average of 31.4%. This means that when inspectors cite 393.126B, they place your vehicle out of service nearly three-quarters of the time. In concrete terms, across all-time enforcement, 106 vehicles were placed out of service for this violation, while only 37 were not. This is a high-severity finding that stops your revenue immediately.
Over the last 90 days, enforcement has been relatively steady, with 16 citations issued. Monthly data from the past year shows citations clustering in June, July, September, and October, with lower frequencies in May, November, and December.
Who gets cited most
Our inspection records show geographically concentrated enforcement. Texas leads with 32 citations in the last 180 days and a 71.9% out-of-service rate. Illinois follows with 2 citations (50.0% OOS rate), and Iowa with 1 citation (0.0% OOS rate). The vast majority of 393.126B citations occur in Texas, reflecting heavy activity in scrap recycling and auto demolition hubs in that state.
By carrier, our data shows fleets such as Transportes Larmex SA de CV and Featherlite Logistics LLC with 4 citations each, and Trailblazer Transport LLC with 3 citations. These figures represent all-time enforcement history and do not imply systemic negligence, but they do indicate that carriers in the compressed-cargo and drayage sectors encounter this code more frequently.
How severe is this compared to similar codes
The Vehicle Maintenance category contains several high-volume codes. Inoperable required lamps (393.9) appears 660,737 times with only a 15.4% out-of-service rate, making it far more common but far less severe. Inspection and repair maintenance general (396.3) shows 236,919 citations with a 45.3% OOS rate—more citations than 393.126B, but still a lower out-of-service likelihood. No proof of periodic inspection codes (396.17C-PI and 396.17) together exceed 400,000 citations but have a 0.0% out-of-service rate, meaning they generate citations without stopping equipment.
In contrast, 393.126B's 74.1% out-of-service rate puts it in a high-severity tier. When this code is cited, the inspector's decision to remove your vehicle from service is nearly automatic, underscoring its safety-critical nature.
How to avoid it
Our co-occurrence data reveals that 393.126B is often found alongside lighting and visibility defects—codes 393.9 (inoperable lamps) and 393.9TS (inoperative turn signal) each co-occurred 4 times in the last 90 days, and 393.60C (glazing/window obstructions) 3 times. This suggests that inspections flagging cargo securement also catch deferred maintenance. A thorough pre-trip inspection catches both.
Based on the vehicle makes most frequently cited—Freightliner (49 citations), Other makes (33), and Kenworth (28)—there is no single make at higher risk; the pattern reflects market share in the scrap and drayage sectors.
Here are concrete steps to avoid this citation:
-
Inspect your load before every trip. Check that all flattened or crushed cargo is fully contained within the trailer walls or bed, with no material protruding or sitting loose. Run your hand along binding points to confirm straps, chains, or braces are tight.
-
Use appropriate restraint hardware. For compressed metal, auto bodies, or crushed material, use DOT-compliant chains, tensioners, and load locks rated for the weight and dimensions of your cargo. Do not rely on gravity or friction alone.
-
Block and brace against movement. Flattened cargo can shift if the vehicle brakes hard or corners sharply. Use blocking boards, angle iron, or proper load bars to prevent side-to-side and forward-backward motion.
-
Verify securement before each stop. After fueling, backing into a dock, or waiting at a shipper, re-check that nothing has shifted and that no restraint has loosened.
-
Document your load configuration. Take photos of how your cargo is secured before you leave the shipper. If you are cited and the load has not moved, this documentation can support your defense.
-
Complete a full pre-trip inspection, including lighting. Since 393.126B co-occurs with lamp and visibility defects, make certain your headlights, taillights, turn signals, and reflectors are all functional before departure.
A 74.1% out-of-service rate means this violation stops your truck. The cost of 30 minutes of proper load inspection at the shipper is far less than the revenue and compliance impact of an out-of-service order at roadside.
