What 393.124C means in plain language
FMCSR 393.124C addresses how concrete pipe must be secured on your vehicle. The regulation requires that concrete pipe loads be fastened according to specific securement standards designed to prevent the load from shifting, rolling, or falling during transport.
This is not about how much tie-down material you use or generic cargo loading. It's about whether concrete pipe specifically meets the method and placement rules set out in the securement regulations. If an inspector finds that your concrete pipe isn't secured in the manner required by those standards, you'll receive a 393.124C citation.
The violation can occur whether your load has shifted during transport or an inspector determines during a roadside inspection that your securement setup doesn't meet the standard—even if the load hasn't moved.
What our enforcement data actually shows
Across our 13 million+ inspection records, 393.124C is an extremely rare violation. Our database shows 5 all-time citations for this code, with 4 issued in the last 12 months and 2 in the last 90 days. This ranks 393.124C at #2406 out of 3,036 FMCSR codes by citation volume.
What's striking about this code is its out-of-service rate: 100.0%. Every single citation on record—all 5—resulted in the vehicle being placed out of service. This is dramatically higher than the all-FMCSR average OOS rate of 31.4%, indicating that when inspectors cite 393.124C, the securement failure is serious enough to warrant immediate removal from service.
The rarity of citations combined with the perfect OOS rate suggests two things: concrete pipe loads are not commonly encountered in routine roadside inspection, and when they are and a violation is found, it's treated as an operational safety issue that prevents continued operation.
Who gets cited most
Over the last 180 days, citations for 393.124C appeared in Iowa and North Carolina, with 1 citation each. Both jurisdictions had a 100.0% out-of-service rate, consistent with the nationwide pattern.
Our all-time carrier data shows that citations for this violation have been distributed across multiple fleets: Spoerl Trucking Inc, Dwight Lamar Davis, Fulford & Jones Asphalt Inc, Juan Caballero Alberto, and IRent Solutions Inc each have 1 citation on record. This pattern suggests the violation is not concentrated among a particular carrier or fleet type but occurs sporadically across different operators who haul concrete pipe.
How severe is this compared to similar codes
393.124C falls within the Vehicle Maintenance category alongside codes like 393.9(a) (Inoperable required lamps, 660,737 citations, 15.4% OOS rate) and 393.11 (Lighting devices/reflectors, 179,734 citations, 1.8% OOS rate). These codes are cited far more frequently and have much lower OOS rates, suggesting that cargo securement violations for concrete pipe are treated as more serious when they do occur.
Compare this to 396.3(a)(1) (Inspection/repair/maintenance - general), which has 236,919 citations and a 45.3% OOS rate. While that code is cited thousands of times more often, its OOS rate is lower than 393.124C's perfect 100.0% rate, underscoring how critical the inspectorate views concrete pipe securement failures.
How to avoid it
Before you load:
- Inspect all tie-downs, chains, and straps for damage or wear. Our inspection data shows that damaged tiedowns (393.104F3) appeared in 1 inspection involving cargo securement issues over the last 90 days, indicating that compromised securement hardware is a red flag.
- Review the specific securement requirements for concrete pipe in your carrier's load procedures or the FMCSR securement rules. Concrete pipe requires different fastening methods than general cargo.
- Ensure tie-down equipment is rated for the weight and geometry of concrete pipe. Pipe can be difficult to secure because of its round shape and weight distribution.
During your pre-trip:
- Walk the entire load and physically check that concrete pipe is immobilized according to spec—not just resting on the deck with one or two straps.
- Confirm that all securement points on your vehicle (where tie-downs attach) are intact and not bent or cracked.
- Test the tightness of tie-downs by hand; they should not move when you pull on them.
On the road:
- Do not rely on a single tie-down system for concrete pipe. Redundancy is built into the securement rules for this reason.
- If you must re-secure your load during a trip, do so in a safe location and treat it as a full re-inspection before continuing.
- Remember that a roadside inspector will verify securement method, not just whether the load hasn't moved. Even if nothing has shifted, improper securement can result in a citation and immediate out-of-service order.
The 100.0% out-of-service rate for this code means that if you're cited, your vehicle will not leave the inspection site under its own power until the violation is corrected. Prevention is far simpler than dealing with that roadside outcome.
