What happens when you're cited for worn steering components under 393.53? See OOS rates, CSA points, and what to do next based on 13M+ inspection records.
Ranks #3,037 of 3,146 FMCSR codes by citation frequency.
Steering system components (universal joints, ball joints, tie rods, drag links, pitman arms) are worn, fatigued, or defective.
Direct answers grounded in TruckCodex inspection data
No. Across our inspection database, 393.53 citations have resulted in a 0.0% out-of-service rate. While the code is technically OOS-eligible, the evidence shows inspectors are not placing trucks out of service for this violation. That said, the underlying condition—worn steering components—is a safety issue and should be repaired promptly to avoid escalation or a more serious citation on a future inspection.
This violation carries a severity weight of 7 points in the CSA BASIC 5 category (Vehicle Maintenance). Your actual CSA point total depends on how the violation is counted in your 30-month safety profile: typically one point per citation, but the FMCSA applies a severity multiplier based on inspection outcomes. A 393.53 citation adds to your carrier's safety record and can affect insurance and customer audits.
In context, 393.53 is less commonly cited than related maintenance codes. For comparison, inoperable required lamps (393.9a) has 660,737 citations with a 15.4% OOS rate, and general inspection/repair/maintenance violations (396.3a1) have 236,919 citations with a 45.3% OOS rate. The 393.53 severity weight of 7 is substantial, placing it in the Vehicle Maintenance BASIC 5 category—meaning it affects your carrier's safety profile directly.
Yes. If you believe the inspection was inaccurate or the inspector incorrectly identified worn steering components, you can file a Request for Data Reconsideration (RDR) with the FMCSA through the DataQs portal. Provide documented evidence: photos of the components, maintenance records showing recent service, or a statement from your technician. The FMCSA has 30 days to review. Steering component findings are equipment-based (not documentation), so you'll need physical evidence to support your dispute.
Our inspection records show zero citations for 393.53 in the last 12 months, last 90 days, and all-time in our database. This is an exceptionally rare citation—either because the violation is seldom found during roadside inspections, or inspectors may cite related codes instead. Despite its rarity, steering system wear is a critical safety issue and should be addressed before an inspector does encounter it.
Our 13 million+ inspection records show zero 393.53 citations, making it one of the rarest FMCSR violations in the database. This likely reflects a combination of factors: many carriers perform preventive steering maintenance, wear-and-tear failures are less obvious during a quick roadside visual inspection, or defects may be cited under broader codes like general mechanical defects. However, the rarity does not diminish the safety risk—steering failure is catastrophic on the road.
Yes, despite zero citations in our data. Steering system components (universal joints, ball joints, tie rods, drag links, pitman arms) wear gradually and are safety-critical. Building a preventive maintenance schedule—quarterly or per manufacturer specs—will keep your trucks inspection-ready and reduce the risk of catastrophic failure. Document all steering service in your vehicle records. When an inspector does pull you over, proof of regular steering maintenance is your strongest defense.
