FMCSR 393.110B – Cargo Securement (Logs): Driver Q&A

Yes — almost certainly. Across all-time inspection records, 393.110B carries a 96.6% out-of-service rate (2,927 of 3,031 citations resulted in OOS). That is more than three times the all-FMCSR average OOS rate of 31.4%. Even though the code is technically listed as OOS-eligible "no" on paper, the real-world enforcement data tells a very different story: inspectors placed drivers out of service on 2,927 separate occasions. If your logs aren't secured correctly, plan on parking until the securement meets the standard.

393.110B carries a severity weight of 7 in the CSA scoring system. That base score is then multiplied depending on how recently the violation occurred: inspections within the last 6 months receive a 3× time-weight multiplier, inspections 6–12 months ago receive a 2× multiplier, and older inspections receive a 1× multiplier. So a fresh citation translates to an effective score of 21 points in the Cargo-Related BASIC before any unsafe-driving or crash-involvement multipliers are applied. Points attach to both the driver and the carrier.

Re-secure all logs before moving the vehicle, then audit the rest of the rig. Our inspection records show that in the last 90 days, 393.110B frequently appears alongside several other violations on the same inspection sheet: 393.9 (inoperable required lamp) in 125 shared inspections, 396.17C (no proof of periodic inspection) in 80, 393.95A (fire extinguisher missing/defective) in 58, 393.104B (damaged tiedown) in 56, and 393.78 (windshield defect) in 53. That pattern means inspectors citing you for log securement are actively looking at your whole unit. Fix the securement, carry your periodic inspection paperwork, check every lamp, and confirm your fire extinguisher is serviceable before re-entering traffic.

It is far more serious than most peer codes in the Vehicle Maintenance category. For comparison, our database shows 393.9(a) (inoperable required lamps) has a 15.4% OOS rate across 660,737 citations, and 393.11 (lighting devices/reflectors) sits at just 1.8% across 179,734 citations. The 96.6% OOS rate for 393.110B dwarfs both of those, and it stands at more than three times the all-FMCSR average of 31.4%. While 393.110B is ranked #438 of 3,036 FMCSR codes by citation volume — meaning it's not the most common violation — when it is cited, it almost always shuts a driver down.

Yes, you can file a DataQs Request for Data Review (RDR), but success depends on what you're disputing. DataQs allows drivers and carriers to challenge inspection findings with FMCSA. Because 393.110B is an equipment/physical-condition violation rather than a documentation issue, a successful challenge typically requires evidence that the inspector's findings were factually incorrect — for example, photos taken at the scene showing compliant securement, or a signed statement from a qualified party confirming the logs met the standard. Documentation-only errors (wrong unit number, wrong driver) are generally easier to remove. File the RDR at the FMCSA DataQs portal and include all supporting evidence at the time of submission.

Texas leads by a wide margin. In the last 180 days, our inspection records show Texas issued 661 citations for 393.110B — with 634 of those resulting in OOS (a 95.9% rate). Iowa came in second with 70 citations, all 70 resulting in OOS (100.0%), and North Carolina was third with 51 citations, also 100% OOS. Illinois (22 citations, 95.5% OOS) and New Mexico (10 citations, 100% OOS) round out the top five. If your log-hauling routes run through any of these states, enforcement exposure is significantly higher than in the rest of the country.

It cannot wait. With a 96.6% all-time OOS rate, 393.110B is the kind of violation that stops you at the roadside, not at the shop. Beyond the immediate OOS risk, the 90-day citation volume — 395 inspections in our records — shows this code is being enforced actively right now. The monthly trend over the last 12 months peaked at 210 citations in July 2025 and has remained above 127 citations every month since. There is no slow season for this violation. Correct the securement before the vehicle moves; every mile driven with improperly secured logs is a live OOS exposure on any scale.

It follows both you and your carrier. Under FMCSA's CSA system, a violation cited on a roadside inspection is recorded against the driver's PSP (Pre-Employment Screening Program) record and contributes to the carrier's Cargo-Related BASIC score simultaneously. The 7-point severity weight for 393.110B applies to both records, time-weighted by how recently the inspection occurred. This means a new carrier doing a pre-hire PSP check will see the citation, and your previous carrier's BASIC score absorbs the points for the inspection period as well. Drivers and carriers each have independent incentives to ensure log securement is correct before every trip.
