What 393.124 means in plain language
FMCSR 393.124 requires that concrete pipe transported on your truck be secured according to specific cargo securement rules. This isn't about loose straps or casual tie-downs—the regulation sets minimum standards for how concrete pipe (a heavy, rigid cargo) must be restrained to prevent it from shifting, falling, or rolling during transit.
If an inspector found your concrete pipe not secured in accordance with those rules, they're citing you for failing to meet those requirements. The violation covers the securing devices themselves, their attachment points, and how they're tensioned and maintained.
What our enforcement data actually shows
Our inspection records show that 393.124 is rarely cited—across 13 million inspections in our database, we see 195 all-time citations for this code, ranking it #1220 out of 3,036 FMCSR codes by volume. In the last 12 months, there were 44 citations, and in the last 90 days, just 8.
What's striking is the out-of-service rate. Of the 195 times this violation was cited, 182 resulted in an out-of-service order—a 93.3% OOS rate. For context, the all-FMCSR average out-of-service rate is 31.4%. This means when inspectors find concrete pipe not properly secured, they almost always deem the vehicle unsafe to operate until corrected. This code sits in the BASIC 5 category with a severity weight of 7, reflecting how seriously regulators treat cargo securement failures.
Who gets cited most
Across the last 180 days, enforcement has been concentrated in three states. Texas led with 12 citations, all resulting in out-of-service orders (100% OOS rate). North Carolina had 4 citations, also 100% OOS. Illinois recorded 2 citations with a 100% OOS rate.
Our data shows fleets such as J B HUNT TRANSPORT INC with 16 all-time citations for this code, and D BRUNOS TRUCKING LLC with 6 citations. These numbers reflect the simple fact that large carriers moving high volumes of concrete pipe inevitably encounter more roadside inspections—not a statement about their safety programs.
How severe is this compared to similar codes
Cargo and vehicle maintenance violations span a wide range of severity. Compare 393.124 to three peer codes:
393.9(a)—Inoperable required lamps has 660,737 all-time citations with a 15.4% OOS rate. That's far higher citation volume but a much lower bar for out-of-service action.
396.3(a)(1)—Inspection/repair/maintenance general shows 236,919 citations with a 45.3% OOS rate—more cited than 393.124, but inspectors place vehicles out of service less than half the time.
393.11—Lighting devices/reflectors has 179,734 citations with a 1.8% OOS rate. Again, these violations rarely result in out-of-service orders.
The 93.3% OOS rate for 393.124 stands out. It reflects the safety-critical nature of cargo securement: an unsecured load is an immediate hazard to the driver, other motorists, and the cargo itself.
How to avoid it
Concrete pipe is heavy and unforgiving. A few co-occurring violations in our recent data offer clues about what inspectors are finding alongside cargo securement failures:
-
Coupling devices and tiedown hardware defects appeared twice in inspections citing 393.124 over the last 90 days. Before you load, walk the trailer: check all D-rings, E-track, and anchor points for bent, cracked, or missing welds. Damaged hardware cannot be relied upon.
-
Damaged tiedowns co-occurred twice. Inspect every strap, chain, or cable for fraying, cuts, rust, or bent links. A damaged tiedown can slip under load. Rotate out worn equipment before a trip.
-
Inoperable lamps and lighting defects appeared in a handful of concurrent inspections. While not directly related to cargo securement, they signal a trailer in poor overall condition. If your lighting is neglected, so might your securement hardware be.
-
Brake and tire issues (slack adjusters, tire inflation, relay valves) also appeared. A pre-trip inspection is not just about your cargo—it's about the entire truck-trailer system that keeps that cargo stationary.
Specific actions before you load:
-
Verify your anchor points are secure and free of damage. Concrete pipe creates high lateral loads on curves; anchor points must be rated for the load.
-
Use the correct number and type of tiedowns for your cargo. Concrete pipe requires careful calculation of load distribution—consult your company's cargo securement guidelines or the FMCSA guide.
-
Tension all tiedowns evenly. Uneven tensioning causes the pipe to shift and slide.
-
On long-wheelbase trailers (we see FRHT and PTRB as the most-cited vehicle makes for this violation), pay extra attention to load centering. Concrete pipe can roll if not perfectly centered and chocked.
-
Perform a visual check mid-trip at fuel stops. Even correctly secured cargo can shift or loosen tiedowns during rough roads.
