Direct answers grounded in TruckCodex inspection data
Yes — almost certainly. Our inspection records show a 98.8% out-of-service rate for 393.110B1-C citations across all-time data (1,539 out of 1,558 total citations resulted in OOS placement). This is far above the FMCSR average OOS rate of 31.4%. In the past 90 days, 230 citations resulted in 230 OOS placements. You should expect your vehicle to be placed out of service on the spot during a roadside inspection for unsecured logs.
This violation carries a severity weight of 7 points. CSA scoring multiplies the severity weight by 7 for violations cited within the last 30 days. That means a single recent citation could add up to 49 points to your carrier's CSA score, which factors into the Safety and Maintenance BASIC. For drivers, this violation follows you and your employer on the CSA profile.
Immediate steps:
Do not resume operation until cleared by the inspector.
Yes. At a 98.8% OOS rate, 393.110B1-C is significantly more severe than the FMCSR average of 31.4%. Among peer vehicle-maintenance codes in our database, codes like 393.9 (Inoperable lamps) have only a 6.9% OOS rate and 396.17C-PI (No proof of inspection) has 0.0%. Your logs violation is treated as an immediate safety hazard requiring vehicle removal from service almost every single time it is cited.
Yes, you can file a Request for Data Review (RDR) through FMCSA's DataQs portal, but success depends on whether the citation was factual. If the inspector documented unsecured logs but your securement actually complied with FMCSR standards, you have grounds to contest. Gather evidence: photos of the load at the time of citation, securement diagrams, tiedown condition, and weight distribution data. If the finding is purely observational (inspector saw loose logs), contestation is harder. Consult your carrier's safety or compliance team for support in filing.
Over the last 180 days, our records show the highest citation counts in: California (121 citations, 97.5% OOS rate), Florida (39 citations, 100% OOS rate), and Washington (28 citations, 100% OOS rate). Together these three states account for 188 of the 332 citations we tracked in the most recent six-month period. If you operate in California, extra vigilance on cargo securement is critical.
Very urgent. In the last 90 days alone, 230 citations for unsecured logs were issued — a significant enforcement activity. The past 12 months show consistent pressure: August 2025 saw 97 citations, March 2026 had 124 citations. Nearly every citation results in immediate OOS placement, meaning your truck sits idle until corrected. Lost revenue plus repair downtime makes prevention far cheaper than remediation. Audit your load securement procedures, tiedown condition (we see 393.104B-C co-occur 22 times in 90 days), and driver training now.
Unsecured logs are cited across many vehicle types, but our data shows Ford (216 citations all-time) and Freightliner (203 citations) are the most commonly cited makes — likely because these are popular commercial platforms, not because they fail more often. The violation appears frequently alongside damaged tiedowns (393.104B-C, 393.104F3), missing equipment (393.95A1, 393.95F), and driver fatigue flags (392.2). Any vehicle can be cited; focus on proper securement regardless of make or model.
