What 392.2-SLLTR means in plain language
This citation targets a specific, serious safety concern: a driver whose ability to safely operate a commercial motor vehicle is compromised because of fatigue, illness, or any similar condition that impairs alertness. The rule doesn't require a crash to occur — it applies the moment an officer determines your condition makes it unsafe to keep driving, or even to have started the trip in the first place.
The "TR" suffix in 392.2-SLLTR distinguishes this variant from other sub-codes under the broader 392.2 umbrella. Inspectors can apply it when they observe signs of impairment during a roadside check — things like slurred speech, drooping eyes, incoherent responses, or visible signs of illness — even if your logbook looks clean.
The practical takeaway: this isn't just about hours-of-service. You can be fully compliant on your ELD and still receive this citation if an officer decides your physical or mental state is unsafe at the time of the stop.
What our enforcement data actually shows
Across our database of 13 million+ inspections, 392.2-SLLTR has accumulated 3,974 all-time citations, placing it at #387 out of 3,036 FMCSR codes by citation volume — a meaningful enforcement presence, not a rarely-used rule. In the last 12 months alone, our inspection records show 2,452 citations issued under this code. In just the last 90 days, there were 473 citations, signaling that enforcement activity is active and ongoing.
Here's where drivers often breathe easier: the out-of-service rate for 392.2-SLLTR is effectively 0.0%. Of 3,974 all-time citations in our database, only 1 resulted in an OOS order. Compare that to the all-FMCSR average OOS rate of 31.4% — this code sits far below that threshold. In nearly every recorded case, drivers were cited and allowed to continue operating.
However, "not placed out of service" does not mean "no consequences." This citation carries a CSA Severity Weight of 8, which is on the higher end of the scale. That weight feeds directly into your CSA Unsafe Driving BASIC score, and it stays on your record for 24 months, affecting both your score and how carriers evaluate you during hiring.
Looking at the monthly trend, our data shows citation counts have been consistently elevated. The highest single month in the last year was July 2025 with 285 citations, and there was no month in that stretch that dropped below 129. That pattern indicates sustained enforcement pressure, not a seasonal blip.
Who gets cited most
In the last 180 days, the top three states by citation count are Colorado with 260 citations, Pennsylvania with 186 citations, and Delaware with 122 citations. All three posted a 0.0% OOS rate, consistent with the national picture for this code. There is no material OOS-rate variation across these states — the near-zero pattern holds regardless of where you're stopped.
Georgia (54 citations) and Florida (48 citations) round out the next tier, again with 0.0% OOS rates. The geographic spread tells you this isn't a regional enforcement quirk — inspectors across the country are applying this code at scale.
On the carrier side, our data shows fleets such as Swift Transportation Co of Arizona LLC (USDOT 54283) with 15 all-time citations and Western Express Inc (USDOT 511412) with 15 citations leading the count, followed closely by J B Hunt Transport Inc (USDOT 80806) with 14 citations and Federal Express Corporation (USDOT 86876) with 12 citations. These are among the largest carriers by fleet size in the country, so citation volume here reflects exposure, not necessarily a disproportionate safety problem.
How severe is this compared to similar codes
The 392.2 family of codes is enormous. The parent code 392.2 — Operating a CMV while ill or fatigued — has accumulated 1,208,164 all-time citations in our database with a 0.8% OOS rate. That's a dramatically higher volume than 392.2-SLLTR's 3,974 citations, which tells you this specific sub-code is one of the less commonly applied variants within the family.
Looking at a closer peer, 392.2-SLLSR carries 191,232 all-time citations with a 0.1% OOS rate — roughly 48 times the citation volume of 392.2-SLLTR. Another variant, 392.2-SLLTCD, shows 85,391 citations with a 0.0% OOS rate, similar to this code's near-zero OOS profile.
One peer code worth flagging is 392.2-SLLEQP, which sits at 72,352 citations but a 2.4% OOS rate — that's the highest OOS rate among the close peer group and a notable outlier. Your code, 392.2-SLLTR, doesn't carry that OOS risk, but the CSA Severity Weight of 8 still makes it one of the more damaging citations you can absorb without being placed out of service.
How to avoid it
The co-occurring violation pattern in our data gives a clear picture of what inspections that result in a 392.2-SLLTR citation look like. Use these action items before and during every pre-trip:
-
Document your periodic inspection proof. The most common co-occurring code in the last 90 days is 396.17C-PI (No proof of periodic inspection), appearing in 54 of the same inspections. Carry your current periodic inspection documentation in the cab, not just in your carrier's files.
-
Know the other 392.2 sub-codes. Our data shows 392.2-SLLSR (27 shared inspections), 392.2-SLLTCD (23 shared inspections), and 392.2-SLL (22 shared inspections) all appearing alongside this citation. When an officer finds one fatigue or illness-related indicator, they frequently look for more. A single stop can generate multiple 392.2-family citations.
-
Keep your CDL valid and accessible. Code 383.23A2-LCDLN — operating without a valid CDL — appeared in 17 of the same inspections. An officer who suspects impairment will verify every credential. Make sure your CDL is current and in your possession.
-
Check your HOS records for accuracy. False record of duty status (395.8E-HOSPD) appeared in 14 shared inspections. If your ELD or paper log doesn't match observable driving behavior or your physical state, it makes a fatigue citation much easier to sustain.
-
Conduct a real self-assessment before starting your shift. Freightliner-badged trucks account for 985 of all-time 392.2-SLLTR citations — the most of any make. No matter what you're driving, the citation follows the driver, not the truck. Before you key the ignition, honestly evaluate your alertness. If you slept poorly, are fighting illness, or feel cognitively slow, delay departure and document why. That paper trail protects you if a dispatch dispute arises later.
-
Verify your vehicle identification markings are correct. Codes 390.21TB2-DOT (14 shared inspections) and 390.21TB1-MC (13 shared inspections) both appeared alongside this citation, suggesting inspections that find one problem tend to find others. A complete pre-trip that covers placards, markings, and documentation reduces your total citation exposure across the board.
