What 393.132(b) means in plain language
FMCSR 393.132(b) requires that dressed lumber, building products, and similar cargo be properly secured to prevent shifting, falling, or becoming a hazard during transport. "Dressed lumber" refers to finished wood products—typically planed, cut to standard dimensions, or otherwise processed for construction or retail sale—as opposed to rough-cut timber.
When an inspector cites you for this violation, they've determined that the cargo securing devices, tie-downs, blocking, bracing, or other methods weren't adequate to keep the load stable under normal driving conditions. This includes sudden stops, turns, and road vibration. The citation isn't about the type of cargo itself; it's about how it was fastened or restrained in the truck.
What our enforcement data actually shows
Across our 13 million+ inspection records, 393.132(b) citations are rare but severe. All-time, we've recorded 141 citations for this violation. In the last 12 months, there were 0 citations, and in the last 90 days, 0 citations—meaning this is an infrequently cited code nationwide, ranking #1325 out of 3,036 FMCSR violations.
What makes this code stand out: the out-of-service rate is extraordinarily high. Our data shows that 139 of the 141 all-time citations resulted in immediate out-of-service orders—a 98.6% OOS rate. For context, the all-FMCSR average out-of-service rate is 31.4%. This code's rate is more than three times higher, meaning that when an inspector finds a cargo securement failure on dressed lumber or building products, your truck is almost certainly being pulled from service until the problem is corrected.
Who gets cited most
Because citation volume for this code is low (141 all-time), geographic hotspots are not pronounced. However, our data shows fleets such as G & G Trucking of New Jersey LLC, Cadence Premier Cargo Inc, and Asano Logistics Inc each accumulated 3 citations over the inspection history we track. This does not indicate a pattern of negligence—rather, these carriers transport higher volumes of dressed lumber and building products, which increases exposure to inspection.
Freightliner and Freightliner-based vehicles (FRHT and FREIGHTLIN designations combined) account for 28 of the 141 citations, reflecting the prevalence of these chassis in construction material transport. Peterbilt (PTRB) vehicles were cited 9 times.
How severe is this compared to similar codes
393.132(b) sits in the Vehicle Maintenance category alongside codes like 393.9(a) (Inoperable required lamps: 660,737 citations, 15.4% OOS rate) and 396.3(a)(1) (Inspection/repair/maintenance - general: 236,919 citations, 45.3% OOS rate). Those codes are cited far more frequently but trigger out-of-service orders at much lower rates.
The extreme OOS rate for 393.132(b)—98.6%—reflects that cargo securement failures are a safety-critical defect. An unsecured load can cause accidents, injury, or property damage. Inspectors treat this as a go/no-go issue: if the load isn't secure, the truck cannot legally move.
How to avoid it
If you haul dressed lumber, building products, or similar cargo, take these steps before every trip:
- Inspect tie-down equipment before loading. Check straps, chains, binders, and load bars for damage, wear, or corrosion. Frayed webbing, broken D-rings, or weakened chains will fail under load stress.
- Know your load limits and tie-down capacity. Verify that the number and strength of your securing devices match the weight and dimensions of the cargo. Dressed lumber bundles are heavy; one strap is never enough.
- Block and brace the load. Use lumber stops, edge boards, or blocking on the trailer floor and walls to prevent the cargo from shifting side-to-side or front-to-back during braking and turning.
- Distribute weight evenly. Load heavier bundles low and centered to improve stability. Uneven loading increases the chance of tipping or sliding during a turn or emergency stop.
- Double-check after loading. Walk around the trailer. Look for gaps between bundles and tie-downs, loose straps, or anything that appears to sag or shift when you shake it gently.
- Review your load plan with dispatch. If you're hauling a mixed load (lumber plus other freight), confirm that the securement method accounts for all cargo and that no item can move independently.
This citation carries a CSA severity weight of 6, meaning it will impact your safety record. The near-certain out-of-service outcome also means delays, missed deliveries, and potential lost revenue while you re-secure the load. Prevention through pre-trip inspection is far cheaper than roadside downtime.
