What 393.124(f) means in plain language
FMCSR 393.124(f) requires that concrete pipe loaded on your truck be secured according to specific rules laid out in the regulation. If an inspector finds your concrete pipe is not properly restrained, blocked, or braced during a roadside inspection, you can be cited for violating this code.
Concrete pipe is heavy, rigid cargo. The securement rules exist to keep it from shifting, falling, or causing instability during transit. This applies whether you're hauling one length of pipe or a full load stacked multiple ways. The inspector will check that your blocking, bracing, tie-downs, and load distribution meet the standard—it's not subjective, and there's no partial credit for "almost" securing it right.
What our enforcement data actually shows
Across our 13 million+ inspection records, 393.124(f) is a rare citation. Our database shows only 3 all-time citations for concrete pipe securement violations. In the last 12 months and last 90 days, we recorded zero citations for this code.
When it is cited, it carries real consequences. All 3 historical citations in our records resulted in the vehicle being placed out of service—an OOS rate of 100.0%. That is dramatically higher than the all-FMCSR average OOS rate of 31.4%. This tells you that when an inspector writes this violation, the securement failure is usually serious enough to ground the truck.
Ranked #2551 of 3,036 FMCSR codes by citation volume, this code is uncommon. But its OOS rate underscores that cargo securement is not a minor infraction.
Who gets cited most
Because only 3 citations exist in our all-time database, geographic and carrier concentration is limited. Our data shows carriers such as Kemper Trucking Inc (USDOT 513989), Gardner Inc (USDOT 720382), and CBG Inc (USDOT 3191874) each with 1 citation. No single state or carrier dominates the enforcement pattern.
Vehicle makes cited include Fontaine T, Mack, Peterbilt, and Talbert MF—each with 1 citation. The rarity of this violation means you should not assume it happens only on certain equipment types.
How severe is this compared to similar codes
In the Vehicle Maintenance category, peer codes show a wide range of citation frequency and OOS impact. Inoperable required lamps (393.9(a)) generates 660,737 citations with a 15.4% OOS rate—far more common but less likely to be removed from service. Inspection/repair/maintenance general violations (396.3(a)(1)) account for 236,919 citations with a 45.3% OOS rate, indicating when they're cited, about half result in OOS.
No proof of periodic inspection codes (396.17C-PI and 396.17(c)) combined represent 410,412 citations but carry a 0.0% OOS rate, suggesting they are often warnings or administrative violations. Slack adjuster defects (393.47E) total 180,363 citations at 0.0% OOS.
The 100.0% OOS rate for 393.124(f) stands out among its peers. When enforcement happens, it is treated as a critical safety failure—not a warning, not a paperwork issue.
How to avoid it
Before you load:
- Inspect the trailer bed, bulkheads, or flatbed for damage, warping, or missing tie-down anchor points. Concrete pipe requires solid blocking surfaces.
- Verify all tie-down hardware (chains, straps, clevis hooks, D-rings) is present, undamaged, and rated for the weight of your cargo.
- Check the tarp or covering system if required for your load configuration.
During loading:
- Confirm blocking and bracing are positioned to prevent pipe from rolling, shifting forward, backward, or sideways during acceleration, braking, and turns.
- Distribute weight evenly across the trailer. Concrete pipe is dense; uneven loading creates instability and puts stress on securement.
- Use the correct number of tie-downs for the length and diameter of pipe. More tie-downs are safer; fewer than required is a violation.
- Secure pipe perpendicular to the direction of travel whenever possible. Pipe running lengthwise is harder to secure and more prone to failure under hard braking.
Before rolling:
- Walk around the loaded trailer and visually confirm nothing moves when you push on it.
- Check that no tie-downs are twisted, frayed, or damaged.
- Ensure blocking materials (wood, dunnage, cradles) are not cracked or deteriorating.
- Verify the load height and width are within legal limits and that side securement is tight.
During your trip:
- Avoid sudden acceleration or hard braking, which can test your securement system and expose weaknesses.
- After the first 50 miles, pull over at a safe location and re-inspect the load. Vibration can loosen tie-downs on initial hauls.
- If you hear shifting sounds or feel unusual handling, pull over immediately and check the load.
Concrete pipe securement is not negotiable. Because the OOS rate is 100% when cited, the cost of failure is not a fine—it is losing productivity, facing customer delays, and the safety risk to yourself and other road users. Invest time in proper securement every single load.
