What this violation means

One or more leaves in a leaf-spring assembly cracked, broken, or missing. OOS. Suspension can shift under load, changing geometry and overloading remaining leaves.

How often this is cited (last 24 months)

In the last 24 months, 393.207B was cited 2,256 times at roadside inspections against 1,666 carriers, and 50% of those citations were out-of-service violations. It ranks #37 among the violation codes in our records by citation count. Most recent citation on record: Oct 13, 2026.

Why this gets cited

Overloading. Fatigue at 800K+ miles. Improper repair (welded spring — never weld a leaf spring, replace it). Off-pavement use beating suspension.

How to fix / prevent

Replace the affected spring pack. Don't replace just one leaf — replace the matched set for that axle. Air-ride conversions on retrofit trucks eliminate this category of failure.

Out-of-service criteria

Yes — this violation IS out-of-service eligible. When an inspector finds 393.207B during a Level 1, 2, or 3 inspection, they can place the Vehicle OOS using the North American Standard Out-of-Service Criteria. OOS means the truck cannot move from the inspection site until the defect is corrected (vehicle OOS) or the driver is replaced (driver OOS). For carriers, every OOS violation adds time-weighted points to your CSA Vehicle Maintenance BASIC — and it shows in the public SMS data within 30 days. For drivers, an OOS event stays on PSP for 3 years.

CSA / SMS impact

393.207B carries a severity weight of 4/10 in FMCSA's Safety Measurement System (SMS). Higher weights mean faster CSA percentile movement. Combined with a time-weighting factor (2× for citations within the last 6 months, decaying over 24 months), this violation can move your Vehicle Maintenance BASIC percentile significantly if it stacks with similar citations across your fleet. The threshold for FMCSA intervention is the 65th percentile for most BASICs (50th for Hazmat and Passenger Carrier). Once you cross that, FMCSA can send a Warning Letter, Off-Site Investigation, or full Compliance Review.

How to read this: a single citation rarely puts you over threshold — it's the pattern. Track your inspection rate per power unit and aim for OOS rate under 5% (industry average is 21%).

Frequently Asked Questions

Can I be placed out of service for 393.207B?
Yes. 393.207B is on the North American Standard Out-of-Service Criteria list. An inspector who finds this during a Level 1, 2, or 3 inspection can place the Vehicle OOS at the inspection site. The truck cannot move until the defect is corrected. For vehicle-side OOS, that usually means a mobile mechanic or tow to the nearest shop. For driver-side OOS (HOS, CDL, drug/alcohol), it means the driver is removed from service and a qualified replacement must arrive before the truck can continue. Pro tip: do a thorough pre-trip every shift and address any issue listed in 49 CFR 393 before pulling onto the road — that's the only reliable way to avoid this one.
How long does 393.207B affect my CSA score?
393.207B stays in your CSA Vehicle Maintenance BASIC for <strong>24 months</strong> from the inspection date. The impact is time-weighted: 3× points during months 0-6, 2× during months 7-12, 1× during months 13-24, then it drops off. Severity weight is 4/10, so each citation contributes 12 points in the first 6 months and decays from there. On the driver's PSP report, the same citation stays visible for <strong>36 months</strong> — and a 5-year history of driver violations is available to motor carriers performing a hire review. If the citation is later dismissed in court (DataQs challenge succeeds, or the underlying ticket is dropped), the SMS record can be removed via FMCSA's DataQs portal — but you have to actively file the challenge.
What's the difference between 393.207B and similar codes?
393.207B is in the 8-code group sharing the same BASIC. The closest siblings are: <strong>396.9C2</strong> (Operating vehicle declared out-of-service); <strong>393.75A</strong> (Flat tire or audible air leak); <strong>393.75A1</strong> (Tire ply or belt material exposed). Inspectors often cite multiple sibling codes from the same inspection — for example, a tire condition violation can simultaneously trigger codes for tread depth, sidewall, and inflation pressure. When you get cited under one sibling, check the report for the others before signing — they all count separately against CSA scoring.
How often is 393.207B cited?
In the last 24 months, 393.207B was cited 2,256 times at roadside inspections against 1,666 carriers, and 50% of those citations were out-of-service violations. It ranks #37 among the violation codes in our records by citation count. Most recent citation on record: Oct 13, 2026.
