What 393.124(c) means in plain language
FMCSR 393.124(c) governs how concrete pipe must be secured on your vehicle. The regulation requires that concrete pipe be fastened and braced according to specific securement standards—not loose, not shifting during transit, and not positioned where it could fall or cause weight distribution problems.
When an inspector cites you for this violation, they've found that your concrete pipe either wasn't tied down properly, wasn't blocked or braced to prevent movement, or wasn't loaded in a way that meets federal standards. This applies whether you're hauling one section of pipe or multiple pieces stacked on a flatbed or specialized pipe carrier.
The violation is straightforward: concrete pipe is heavy, rigid cargo that requires deliberate securement to keep it in place during normal driving and emergency stops. Inadequate securement puts other road users at risk and violates the standard.
What our enforcement data actually shows
Across our 13 million+ roadside inspection records, 393.124(c) has drawn only 10 all-time citations. In the last 12 months, we recorded zero citations for this code. Over the past 90 days, the citation count remains at zero.
However, when this code is cited, the consequences are severe: 100% of the 10 all-time citations resulted in an out-of-service order. This is a stark contrast to the all-FMCSR average out-of-service rate of 31.4%. While the low enforcement volume makes this a rare citation—ranked #2191 of 3,036 FMCSR codes by total citation count—inspectors who flag this violation view it as a critical safety defect warranting immediate vehicle removal from service.
The zero citations in the past 12 months and 90 days suggest that most drivers and fleets are managing concrete pipe securement correctly, or that inspectors encounter this cargo type infrequently on the roadside.
Who gets cited most
Our inspection records show concrete pipe securement citations distributed across 10 different carriers, each with one citation. The carriers cited include THE QUIKRETE COMPANIES LLC (USDOT 51938), LEFEBVRE & SONS INC (USDOT 213483), VICO CONSTRUCTION CORPORATION (USDOT 494197), WAGGONER CONSTRUCTION INC (USDOT 846945), PARKER TOWING INC (USDOT 1167038), MEDINA TRANSPORT AND SON LLC (USDOT 1472171), NOVA LINES INC (USDOT 2559423), ROAD KING EXPRESS INC (USDOT 2578534), ISL TRUCKING LLC (USDOT 3531195), and ALLEGACY LOGISTICS CORP (USDOT 3899860).
No state dominance is evident in the data—the 10 citations are spread thinly across the enforcement population. This lack of geographic clustering indicates the issue is not concentrated in any single region, but rather occurs sporadically when heavy pipe cargo is improperly loaded.
How severe is this compared to similar codes
In the Vehicle Maintenance category where 393.124(c) sits, citation frequency and out-of-service outcomes vary widely. The data reveals meaningful contrasts:
393.9(a) — Inoperable required lamps generated 660,737 citations with a 15.4% out-of-service rate, making it far more frequently cited but much less likely to result in an OOS order when it is.
396.3(a)(1) — Inspection/repair/maintenance (general) has 236,919 citations with a 45.3% out-of-service rate, indicating it's cited roughly 24,000 times more often than 393.124(c), and when cited, carries a substantially higher probability of OOS placement than lamps.
393.78 — Windshield condition defective reached 157,894 citations with only a 0.3% out-of-service rate, showing that common cosmetic or minor structural defects rarely trigger removal from service.
The 100% OOS rate for 393.124(c) underscores that cargo securement failures are treated as non-negotiable safety violations. Unlike a burned-out lamp or a minor windshield blemish, unsecured concrete pipe creates immediate hazard and draws mandatory vehicle removal.
How to avoid it
If you're hauling concrete pipe, prevent a 393.124(c) citation by observing these concrete steps during pre-trip and loading:
-
Inspect tie-down equipment before loading. Check that chains, straps, binders, or other securement hardware are not damaged, frayed, or weakened. Federal securement rules require equipment rated for the load weight and stress.
-
Ensure pipe is blocked and braced. Concrete pipe must not roll or shift side-to-side. Use blocking (wood, plastic, or composite material) under and against the pipe, secured to the vehicle frame or deck.
-
Verify load is balanced. Unbalanced weight distribution can cause the pipe to shift during braking or turning. Load heavier sections toward the front and center of the cargo area.
-
Use redundant securement. Don't rely on a single strap or chain. Use at least two independent points of attachment spaced along the pipe's length.
-
Know the rated capacity of your securement hardware. If your binders or straps are rated for 5,000 pounds and your pipe section weighs 6,000 pounds, you don't meet the standard—upgrade to heavier-duty equipment.
-
Perform a shake test before departure. Gently push the pipe from the side once it's loaded. It should not move or rattle. If it moves, add more blocking or tighten securement.
-
Re-check securement after 50 miles and after any rough road or heavy braking. Vibration and load shifting can loosen tie-downs during transport. A quick roadside verification can prevent an inspector citation.
Because concrete pipe is rigid and heavy, there is no flexibility in how it must be secured. Inspectors enforce this standard with zero tolerance—the 100% OOS rate makes that clear. Invest time in proper loading and securement every time you haul pipe, and you'll eliminate the risk of this citation entirely.
