Direct answers grounded in TruckCodex inspection data
No. Across our inspection records, 392.22A has a 0.0% out-of-service rate—all 794 citations issued in our database resulted in no OOS placements. This is significantly lower than the 31.4% average OOS rate across all FMCSR codes. You will receive a citation, but your truck will not be pulled from service on the spot for this violation.
A 392.22A citation carries a CSA severity weight of 4 points. Your total CSA impact depends on when the violation was discovered relative to your 30-month safety record window. Points are weighted by the discovery date—more recent violations count more heavily. Consult your carrier's safety department or a compliance officer to see how this specific citation affects your current CSA score.
First, document the citation details and notify your fleet safety team immediately. Second, perform a walk-around inspection of your CMV to verify warning device placement and condition. Our data shows 392.22A frequently co-occurs with fatigued driving violations (11 shared inspections in the last 90 days) and improper road-surface placement of devices (11 shared inspections). Check both your in-cab alertness and your emergency triangle/flare setup. Third, file any corrective action with your carrier before your next dispatch.
No. 392.22A ranks #779 out of 3,036 FMCSR codes by citation frequency, with only 794 all-time citations in our database. For comparison, inoperable required lamps (393.9) have 660,737 citations with a 15.4% OOS rate, and slack adjuster defects (393.47E) total 180,363 citations. Emergency warning device citations are relatively uncommon and carry zero out-of-service risk, making them a lower-severity equipment defect.
Yes. You can submit a DataQs (Safety Management System Inquiry) challenge if you believe the citation is factually incorrect or was issued in error. DataQs disputes focus on objective evidence: photos of your warning devices properly displayed, maintenance logs, or inspection records. Warning device violations are equipment-based findings, so documentation proving you had compliant triangles or flares displayed at the time of inspection strengthens a contestation. Submit your challenge within 30 days of the inspection.
In the last 180 days, our records show Iowa leads with 23 citations, followed by Texas with 4 citations, and New Mexico with 1 citation. Iowa accounts for the vast majority of recent enforcement activity for this code. If you operate primarily in Iowa, prioritize pre-trip warning device inspections and ensure your triangles or flares are stored and displayed per regulation.
Immediately. Emergency warning devices must be present and properly displayed on any stopped CMV—this is a pre-trip requirement, not a repair that can wait. Our 90-day trend shows 16 citations, with September 2025 spiking at 17 citations. Because there is zero out-of-service risk, inspectors focus on compliance verification rather than impound. Fix it before your next dispatch to avoid a repeat citation.
Forza Transportation Services Inc (USDOT 2490721) leads with 5 all-time citations for this violation, followed by Schneider National Carriers Inc and NFI Interactive Logistics LLC, each with 4 citations. If you drive for one of these carriers, your fleet safety team may have specific training or procedures for warning device compliance. Check with them about carrier-wide standards that exceed the minimum federal requirement.
