What 392.2-SLLILC means in plain language
This citation comes down to a simple premise: if a driver's physical or mental condition has deteriorated to the point where safely operating the truck is in question, the driver should not be behind the wheel. That covers fatigue and illness, but also any other condition that impairs alertness or the ability to react — whether that's a migraine, a medication side effect, or simply too many hours without real sleep.
The regulation doesn't require a crash or near-miss to trigger a citation. An officer observing signs of impairment — drifting lanes, slurred speech, bloodshot eyes, admission of illness — can write this violation at a roadside stop. The standard is whether your condition made it unsafe to begin or continue driving, not whether you actually caused an incident.
For drivers, the practical message is this: if you feel genuinely unwell or exhausted before or during a run, stopping is not optional — it's the regulatory baseline. Pushing through isn't toughness; it's documented exposure.
What our enforcement data actually shows
Across our inspection database, 392.2-SLLILC has accumulated 5,843 all-time citations. In the last 12 months alone, that number reached 3,555 — meaning roughly 61% of every citation ever written for this code appeared in the past year. In just the last 90 days, inspectors issued 725 citations under this code. That acceleration is significant and worth paying attention to.
Despite the volume, the out-of-service rate for this code is 0.0% across all 5,843 recorded inspections. Not a single driver was placed out of service under this specific code in our records. To put that in context, the all-FMCSR average OOS rate sits at 31.4%. This code is a clear outlier — citations are being written, but they are not resulting in immediate OOS orders.
That said, don't let the 0.0% OOS rate create false comfort. This code carries a CSA Severity Weight of 8, which is at the high end of the scale. Every citation still feeds directly into your SMS Unsafe Driving BASIC, and with 5,843 citations recorded, it ranks #314 out of 3,036 FMCSR codes by total citation volume. It is not a rare or obscure violation — inspectors know it, write it regularly, and the pace is increasing.
Looking at the monthly trend over the last 12 months, citations climbed sharply from 105 in April 2025 to a peak of 377 in July 2025, then settled into a consistent range of 283–327 per month through early 2026. Enforcement attention on this code is not seasonal noise — it has stabilized at a high baseline.
Who gets cited most
Our inspection records show Georgia leading all states with 328 citations in the last 180 days, followed by Pennsylvania at 139 and Indiana at 134. South Carolina came in fourth with 116 citations during the same period. All of these states posted a 0.0% OOS rate under this code, so there is no meaningful variation in OOS outcomes across the top enforcement states — citations are being issued uniformly without OOS placements.
At the carrier level, our data shows fleets such as Federal Express Corporation (USDOT 86876) with 44 all-time citations and J.B. Hunt Transport Inc. (USDOT 80806) with 24 citations appearing near the top of the citation count. High-volume carriers operate more trucks on more miles, which naturally increases exposure — these numbers reflect scale as much as anything else.
Freightliner-badged equipment shows up in 1,440 all-time citations for this code, more than any other make in our records. Volvo, Kenworth, and Peterbilt follow at 453, 423, and 410 citations respectively. This likely reflects fleet composition across the industry rather than any equipment-specific risk, but it reinforces that this violation touches every corner of the trucking market.
How severe is this compared to similar codes
This code sits inside a dense family of 392.2-variant violations. The base code, 392.2 (Operating a CMV while ill or fatigued), has 1,208,164 all-time citations in our database — more than 200 times the volume of 392.2-SLLILC — with a 0.8% OOS rate. That parent code is one of the most-cited violations in our entire dataset.
The variant 392.2-SLLSR has 191,232 all-time citations and a 0.1% OOS rate. Another peer, 392.2-SLLTCD, carries 85,391 citations and a 0.0% OOS rate identical to this code. One peer worth flagging is 392.2-SLLEQP, which has 72,352 citations but a notably higher 2.4% OOS rate — showing that certain sub-variants of this code family do carry real OOS risk depending on context.
392.2-SLLILC, at 5,843 citations, is a lower-volume member of this family. But a CSA Severity Weight of 8 puts it on equal footing with the most serious violations in the Unsafe Driving BASIC, regardless of raw citation count.
How to avoid it
The co-occurring citation patterns in our 90-day data provide a clear roadmap of what inspectors are finding alongside this violation — and where your pre-trip focus should be.
- Audit your hours and ELD before you roll. In our records, 395.8A1-HOSP (failure to have a proper record of duty status) appears in 54 shared inspections with this code, and 395.24 (ELD form and manner) appears in 38. If your logs are out of order, you're giving an inspector a second violation to pair with any fatigue observation they make.
- Carry and verify your medical certificate. Code 391.41APC (operating without a valid medical certificate) appeared in 40 shared inspections. An expired or missing med cert compounds a fatigue stop into a multi-violation inspection fast.
- Have your periodic inspection documentation ready. Code 396.17C-PI (no proof of periodic inspection) showed up in 67 shared inspections — the second-most common co-occurring code. If you can't produce it, the inspection gets longer and the citation list grows.
- Know your own physical baseline before the pre-trip. This violation is written based on what an officer observes about you, not just your truck. If you're fighting illness, document it, notify dispatch, and use your off-duty time legitimately. Starting a run sick or severely sleep-deprived creates the conditions this code was written for.
- Don't underestimate rest stop planning on long-haul routes through GA, PA, and IN. Our data shows these three states generated the most citations in the last 180 days — 328, 139, and 134 respectively. If your route runs through any of them, inspectors in those states are clearly active on this violation.
