393.207E (Cracked/Broken Torsion Bar) — Driver Q&A

Not automatically. Across our inspection records, 393.207E results in an out-of-service placement 41.7% of the time—higher than the 31.4% average OOS rate across all FMCSR codes. Of the 949 total citations we've seen for this violation, 396 trucks were placed out of service and 553 were not. Whether you're grounded depends on the inspector's assessment of the suspension system's safety at the moment of inspection.

It's moderately serious. At 41.7% OOS rate, 393.207E exceeds the national average of 31.4% and ranks higher than common codes like inoperable lamps (6.9% OOS) and windshield defects (0.3% OOS). However, it's less likely to ground you than general inspection/repair failures (45.3% OOS). The data shows that torsion bar damage creates genuine safety concerns—inspectors place these vehicles out of service more often than they let them proceed.

First: stop operating the vehicle and arrange for a certified mechanic to inspect and repair the torsion bar. Second: if grounded, do not drive the truck until repairs are completed and documented. Third: because our inspection records show 393.207E frequently co-occurs with brake tubing issues (44 shared inspections), slack adjuster problems (28), and fuel system leaks (33), have the mechanic inspect those systems too. Fourth: obtain proof of repair to present at roadside if stopped again.

Our inspection records show 143 citations for cracked or broken torsion bars in the last 90 days. In the most recent month (March 2026), there were 60 citations issued, with 37 resulting in out-of-service placements. The monthly trend over the past year ranges from 15 to 66 citations, indicating steady but fluctuating enforcement activity.

Texas dominates 393.207E enforcement. In the last 180 days, Texas accounted for 289 citations—far outpacing all other states in our database. The Texas out-of-service rate stands at 48.4%, meaning nearly half of all 393.207E stops there result in vehicle immobilization. If you operate in Texas, torsion bar maintenance should be a top priority in your pre-trip inspections.

Freightliners account for 316 of the 949 all-time citations (33% of the total), making them by far the most cited make for this violation. Kenworths are second with 136 citations, followed by Volvos (100), and Internationals (76). If you drive a Freightliner, proactive suspension and torsion bar inspection is critical to avoid roadside citations.

Torsion bar cracks and breaks are visual, structural defects—not documentation or record-keeping errors. That makes them factual findings rather than procedural violations. Contesting requires demonstrating either that the bar was not actually cracked or broken, or that the bar's condition does not meet the definition of the violation. If you believe the inspector's assessment was incorrect, DataQs submission through FMCSA's Roadside Data Repository system is the formal path, but you'll need photographic or mechanical evidence supporting your rebuttal.

Yes—frequently. Over the last 90 days, inspections citing 393.207E also cited brake tubing/hose inadequacy in 44 cases, inoperable lamps in 43, fuel system leaks in 33, and defective slack adjusters in 28. This pattern suggests that vehicles with torsion bar problems often have systemic maintenance shortfalls. When cited for 393.207E, expect the inspector to scrutinize your brakes, lights, and fuel system closely—and address all defects found, not just the torsion bar.
