Questions & Answers
Direct answers grounded in TruckCodex inspection data
Will 393.207A put my truck out of service?
Yes — and more often than almost any other violation. Across 11,228 all-time citations in our inspection records, 393.207A carries a 65.0% out-of-service rate. That means nearly two out of every three trucks cited were parked on the spot. For context, the all-FMCSR average OOS rate is only 31.4%, so this violation is more than double that baseline. Technically, 393.207A is not automatically OOS-eligible by the standard CVSA criteria, but inspectors clearly exercise discretion aggressively here — 7,302 vehicles have been placed out of service under this code. Do not assume a citation means you drive away.
How many CSA points does a 393.207A violation add to my record?
A 393.207A citation carries a severity weight of 7 in the CSA scoring system. That base score is then multiplied depending on how recently the violation occurred: violations within 6 months of a crash or inspection review receive the highest multiplier. The 7-weight puts this in the serious-but-not-maximum tier, placing it above purely administrative violations but in the same neighborhood as other equipment defects. The points attach to both the driver's PSP record and the carrier's Vehicle Maintenance BASIC. If you accumulate multiple citations in a short window, the multiplied total climbs quickly — our records show 7,488 citations in just the last 12 months, so inspectors are actively looking for this.
I just got cited for 393.207A — what should I do right now?
Get the suspension repaired before moving the vehicle if you were placed out of service, and document everything. Here is a concrete checklist drawn from the violation patterns our inspection records reveal:
Fix the cited component first — broken or missing leaf springs, U-bolts, or other suspension parts flagged under 393.207A.
Check your brakes and brake hardware — 287 inspections in the last 90 days paired 393.207A with code 393.47E (slack adjuster defective) and 209 with brake OOS violations (396.3A1BOS).
Check all lights — 540 inspections also had a 393.9 inoperable lamp violation.
Confirm your periodic inspection paperwork is current — 195 shared inspections lacked proof under 396.17C.
Get a signed repair order showing the defect was corrected before re-entering service.
Is 393.207A a serious violation compared to other maintenance citations?
Yes — its OOS rate makes it one of the most consequential maintenance codes on record. Our inspection data shows 393.207A's 65.0% out-of-service rate towers over peer codes in the Vehicle Maintenance category. For comparison: 393.9(a) inoperable required lamps has a 15.4% OOS rate across 660,737 citations; 393.78 windshield defects sits at just 0.3% across 157,894 citations; and even 396.3(a)(1) general inspection/maintenance violations come in at 45.3% across 236,919 citations. A defective suspension is treated by inspectors as a genuine safety emergency, not a paperwork issue, and the data backs that up.
Can I contest a 393.207A citation through DataQs?
Yes, you can file a DataQ request for review (RDR) — but the bar is real. Because 393.207A is an equipment violation rather than a documentation or administrative finding, a successful challenge typically requires proof that the cited defect did not exist at the time of inspection — for example, a pre-trip inspection record dated the same day, a maintenance log showing the component was recently replaced, or a signed mechanic's statement. Simply repairing the part after the fact does not erase the violation. Submit your RDR through the FMCSA DataQs portal and attach every piece of supporting documentation you have. Expect the reviewing state agency to scrutinize physical evidence closely given the 65.0% OOS rate this code generates.
Where does 393.207A get cited the most?
Texas by a wide margin, followed by North Carolina and Illinois. In the last 180 days alone, our inspection records show Texas issued 3,494 citations under 393.207A — far outpacing every other state. North Carolina ranked second with 130 citations, and Illinois third with 52. If you run corridors through any of these states, your suspension system will receive heightened scrutiny. North Carolina is particularly aggressive on enforcement outcomes: its OOS rate for this code is 93.1%, meaning nearly every truck cited there was also parked. Texas's rate is 64.9% and Illinois's is 80.8%.
How urgent is it to fix a suspension defect to avoid a 393.207A citation?
Extremely urgent — this violation is trending upward and inspectors are not letting trucks slide. Our inspection records show 393.207A generated 7,488 citations in the last 12 months, with monthly volume climbing steadily: from 592 in May 2025 to a 12-month peak of 840 in February 2026. The 90-day citation count alone stands at 1,824. With a 65.0% out-of-service rate, a deferred repair on a leaf spring, U-bolt, or other suspension component is not a risk you can budget around — odds are greater than 2-in-3 that a roadside inspector will shut you down on the spot. Address suspension defects at the next scheduled PM or sooner if any component is visibly cracked, shifted, or missing.
Does a 393.207A citation follow the driver, the carrier, or both?
Both the driver and the carrier are affected, but in different ways. Under FMCSA's CSA system, a 393.207A citation with its severity weight of 7 is recorded in the Vehicle Maintenance BASIC, which scores against the carrier's safety profile. It also appears on the driver's Pre-Employment Screening Program (PSP) record and can influence future hiring decisions. The carrier bears responsibility for maintaining the vehicle, but the driver is expected to catch suspension defects during pre-trip inspections. Our inspection records show 11,228 all-time citations under this code, meaning both drivers and carriers face real downstream consequences — from CSA percentile increases for the fleet to PSP record entries that follow individual drivers.
