What 392.2SAFCH means in plain language
FMCSR 392.2SAFCH addresses a straightforward but critical safety rule: you cannot operate a commercial motor vehicle if your ability to drive safely is impaired. That impairment can come from fatigue, illness, medication side effects, or any other condition that reduces your alertness or judgment behind the wheel.
The regulation doesn't require you to be visibly sick or sleeping at the wheel. It covers the gray zone where you feel capable but your reflexes, concentration, or decision-making are compromised. An inspector making this citation is documenting their observation that you appeared unfit to operate that vehicle at that moment—whether due to drowsiness, visible signs of illness, slurred speech, or erratic driving behavior.
What matters to enforcement: your actual condition when you're operating the vehicle, not whether you declared it on your logbook or reported it to your dispatcher. If an officer or inspector observes you driving in a state they document as unsafe, that citation reflects the safety risk you posed at roadside.
What our enforcement data actually shows
Across our 13 million+ roadside inspection records, 392.2SAFCH has been cited 23 times all-time, with 14 citations in the last 12 months and 4 in the last 90 days. This code ranks #1881 of 3,036 FMCSR codes by citation frequency—it's uncommon, which reflects how rarely inspectors document this specific violation compared to mechanical or logbook citations.
The most telling number: 0.0% of drivers cited for 392.2SAFCH were placed out of service (0 OOS placements out of 23 all-time). This is substantially lower than the all-FMCSR average of 31.4%. That pattern suggests inspectors are citing the condition without removing you from service—likely because the impairment was marginal, situational, or correctable on the spot (e.g., you acknowledged fatigue and agreed to rest). However, don't interpret a lack of OOS as permission. The citation itself is a formal violation that counts against your record and your carrier's CSA score.
The enforcement trend is stable but low-volume. Over the last 12 months, citations have ranged from 1 to 3 per month, with no spike or seasonal pattern. February 2026 saw the highest month at 3 citations.
Who gets cited most
Our last 180 days of data show this violation concentrated in three states:
- Iowa: 5 citations (0.0% OOS rate)
- Illinois: 1 citation (0.0% OOS rate)
- New Mexico: 1 citation (0.0% OOS rate)
All three states show a 0.0% out-of-service rate, meaning none of the drivers cited in those states were removed from service. Iowa accounts for the bulk of recent enforcement activity on this code.
Across all-time data, BUTCH'S RAT HOLE & ANCHOR SERVICE INC (USDOT 864564) appears twice in our database for this code—more than any other carrier. The remaining citations are scattered across single-citation carriers including owner-operators and small to mid-size trucking companies. Our data shows no pattern suggesting systemic fatigue-management failures at any particular fleet; rather, 392.2SAFCH citations appear as isolated safety observations during routine roadside checks.
How severe is this compared to similar codes
392.2SAFCH falls within the broader "Operating a CMV while ill or fatigued" category, which includes several related codes with markedly different enforcement volumes:
- 392.2 (the parent code): 1,208,164 citations all-time, 0.8% OOS rate
- 392.2-SLLSR: 191,232 citations all-time, 0.1% OOS rate
- 392.2RG: 96,652 citations all-time, 0.1% OOS rate
Your specific code, 392.2SAFCH, sits at the narrow end of that spectrum—only 23 all-time citations. The parent code 392.2 has seen over 50,000 times more enforcement activity. This suggests that 392.2SAFCH represents a particularized circumstance (possibly a specific documentation format or inspector training in certain regions) rather than a commonly cited variation of the fatigue rule.
Compared to all FMCSR codes, your code carries a CSA severity weight of 8, placing it in the moderate range. It won't automatically trigger an out-of-service order, but it does add points to your carrier's FMCSR audit profile if your company is subject to CSA scoring.
How to avoid it
Before every shift, assess your fitness to drive:
- Get adequate sleep. Fatigue is the most common reason this citation is issued. Aim for 7–8 hours before a long haul. If you're running on 4–5 hours, you're at risk even if you feel "okay."
- Address illness head-on. If you have a cold, fever, or medication that makes you drowsy, don't assume you can push through. Call your dispatcher and arrange a rest day or a local run. Your safety and your carrier's CSA record depend on honest self-assessment.
- Check your medications. If you're taking a new antihistamine, pain reliever, or any OTC medicine, read the label for drowsiness warnings. Some medications don't cause visible impairment but still slow your reaction time.
- Eat and hydrate properly. Hunger and dehydration degrade alertness. Pack protein snacks and water to maintain stable energy.
- Know your circadian rhythm. Many drivers are drowsiest in early morning and early afternoon. Schedule breaks or rotate driving duties during your personal low-energy windows.
- Pull over at the first sign of fatigue. Yawning, heavy eyelids, drifting between lanes, or inability to recall the last few miles are all red flags. Stop, move around, drink water, or nap for 20 minutes. An inspection during an impaired run can end with a citation and a CSA hit.
In your pre-trip inspection:
- Review our data on co-occurring violations: 392.2RG (another fatigue code), 390.21TB, and mechanical issues like inoperative turn signals appeared together with 392.2SAFCH in recent inspections. A vehicle in poor mechanical condition adds stress and fatigue; if your truck is nagging you with warning lights or brake issues, fatigue can compound the risk. Complete your pre-trip thoroughly and address mechanical defects before they become a secondary factor in an impairment citation.
- The top vehicle makes cited for this code (RAM, Ford, Chevrolet, Volvo, Freightliner) span multiple manufacturer types, so there's no vehicle-specific pattern. Focus on the driver, not the truck.
If you're already cited:
Your citation is not out-of-service eligible, so you can likely continue your run after the stop. However, do not ignore it. Work with your fleet safety manager or a compliance professional to understand what the inspector observed and to ensure you're rested before your next inspection. A single 392.2SAFCH citation may trigger a follow-up audit or closer scrutiny on your next roadside stop.
