What 393.207(e) means in plain language
A torsion bar is a suspension component that helps absorb road shock and supports your truck's weight. When a torsion bar cracks or breaks completely, it compromises the structural integrity of your suspension system and can affect how your vehicle handles on the road.
This violation is written when an inspector finds visible damage to the torsion bar during a roadside inspection. The bar does not need to be completely severed; a crack is enough to trigger a citation. Torsion bars are commonly found in the front suspension of heavy-duty trucks, and they wear over time due to vibration, road conditions, and general age.
What our enforcement data actually shows
Across our 13 million+ roadside inspection records, 393.207(e) has generated 712 all-time citations and ranks #810 out of 3,036 FMCSR codes by enforcement volume. In the last 12 months and the last 90 days, we recorded zero citations for this violation, indicating it is rare in current enforcement activity.
When inspectors do find a cracked or broken torsion bar, the data shows an out-of-service rate of 38.5%—meaning inspectors placed the vehicle out of service in 274 cases and allowed continued operation in 438 cases. This OOS rate is 7.1 percentage points higher than the all-FMCSR average of 31.4%, suggesting that when torsion bar damage is severe enough to be noticed, inspectors tend to view it as a material safety issue more often than they do for violations overall.
Who gets cited most
Our inspection records do not break down 393.207(e) citations by state in the data provided. However, our database shows that fleets such as Evans Delivery Company Inc (USDOT 38111) and Autotransportes Varela Davila SA de CV (USDOT 1716824) have been cited for this violation. Evans Delivery Company Inc appears in our records with 8 all-time citations for 393.207(e), and Autotransportes Varela Davila SA de CV with 7 citations. This does not indicate negligence; it reflects the fact that these fleets operate larger numbers of vehicles and are subject to more inspections over time.
How severe is this compared to similar codes
Vehicle maintenance violations fall into the same regulatory category. Our inspection records show that 396.3(a)(1)—Inspection/repair/maintenance (general)—has accumulated 236,919 citations with a 45.3% OOS rate, substantially higher than 393.207(e)'s 38.5% rate and reflecting its broader scope. By contrast, 393.9(a)—Inoperable required lamps—has generated 660,737 citations with only a 15.4% OOS rate, indicating that lamp defects are far more common but inspectors place vehicles out of service less frequently for them. The 393.207(e) violation sits in the middle of this range: less common than lamps but, when detected, more likely to result in an immediate out-of-service order than lamp violations.
How to avoid it
Pre-trip inspection:
- Visually inspect the torsion bar on both sides of the front axle before departure. Look for visible cracks, rust patterns that suggest metal fatigue, or any irregularity in the bar's surface. A cracked torsion bar often shows discoloration or a thin line running across the metal.
- Check for uneven ride height; if one corner of your truck sits lower than the other, suspension damage may be present and should be investigated immediately.
Maintenance and fleet ops:
- Have your suspension system inspected by a qualified technician at regular intervals, especially if you operate in rough terrain or frequently hit potholes. Torsion bars degrade slowly; catching a crack early prevents a roadside citation and a potential safety failure.
- Know your vehicle. Across our citation data, Freightliner trucks (103 citations for 393.207(e)) and Kenworth trucks (44 citations) represent the top makes cited for this violation. If you operate one of these makes, add torsion bar inspection to your routine maintenance schedule.
- Do not defer suspension repair. Once a torsion bar is cracked, it will not heal, and continued operation increases the risk of complete failure and loss of control.
