What 392.2-INAT means in plain language
This citation is issued when an officer determines that your ability to safely operate a commercial motor vehicle is impaired — not necessarily by alcohol or drugs, but by fatigue, illness, or any other condition that makes continuing to drive unsafe. The standard is your actual alertness and capability at the moment of the inspection, not a breathalyzer number or a lab result.
In practical terms, an officer can write this citation if you're visibly exhausted, struggling to stay coherent during the inspection, show signs of being sick to a degree that affects your driving ability, or if other evidence at the scene suggests you should not be behind the wheel. It is a judgment call on the officer's part, but it's a judgment call backed by a federal regulation and recorded permanently on your inspection history.
The CSA severity weight for 392.2-INAT is 8 out of a possible 10. That's near the top of the scale. Even a single citation will have a meaningful impact on your Unsafe Driving BASIC score, and that score is visible to shippers, brokers, and your carrier's safety department.
What our enforcement data actually shows
Across our database of 13 million+ inspections, 392.2-INAT has generated 7,877 all-time citations, making it ranked 259th out of 3,036 FMCSR codes by citation volume. That's not a rarely-enforced obscurity — it sits solidly in the active enforcement tier.
Enforcement volume has accelerated sharply in recent months. Over the last 12 months alone, our inspection records show 5,216 citations issued under this code — meaning roughly 66% of the entire all-time total accumulated in just one year. Over the most recent 90 days, 1,159 citations were recorded. Month by month, the trend is consistently high: March 2026 saw 528 citations, July 2025 saw 509, and no single month in the past year dipped below 394 citations (excluding a partial April 2026 count of 13 through the snapshot date).
Despite the elevated severity weight, the out-of-service rate for 392.2-INAT is effectively 0.0%. Across all 7,877 citations in our database, only 3 drivers were placed out of service. For context, the all-FMCSR average OOS rate is 31.4%. This code sits essentially at zero. That means in nearly every case, officers write the citation but allow the driver to continue — a detail that matters for your immediate situation, but it does not reduce the CSA impact one bit. The citation still scores.
Who gets cited most
Looking at the last 180 days, three states dominate the citation count by a wide margin. Georgia leads significantly with 1,196 citations and a 0.0% OOS rate. Arizona comes in second at 217 citations, also at 0.0% OOS. Arkansas ranks third with 108 citations, again with no drivers placed out of service. The OOS rate is uniformly 0.0% across all top states, so there is no meaningful state-to-state variation in that metric — wherever you're cited, the enforcement pattern is: citation written, driver rolls.
On the carrier side, our data shows fleets such as Federal Express Corporation (USDOT 86876) with 82 all-time citations and United Parcel Service Inc (USDOT 21800) with 44 citations leading the count among named carriers. These are high-volume operations with large driver pools, and the numbers reflect that scale.
How severe is this compared to similar codes
The 392.2 family of codes all fall under the same broad Unsafe Driving category, and comparing them puts 392.2-INAT in perspective. The base code 392.2 — also labeled as operating a CMV while ill or fatigued — has accumulated 1,208,164 citations with a 0.8% OOS rate. That's a code enforced at a volume nearly 153 times larger than 392.2-INAT's all-time count. Another peer, 392.2-SLLSR, carries 191,232 citations and a 0.1% OOS rate. And 392.2-SLLEQP, which shares the same category, has a notably higher 2.4% OOS rate across its 72,352 citations — the highest OOS rate among the peer codes in this group.
By comparison, 392.2-INAT's 0.0% OOS rate is the lowest of the group, but its CSA severity weight of 8 is the factor that matters most for your score. A citation that doesn't take you out of service today can still follow your record for years.
How to avoid it
The co-occurring violation pattern in our data tells a clear story. In the last 90 days, 392.2-INAT appeared in the same inspection as Hours of Service and ELD violations frequently — 82 inspections also included a 395.24 (ELD Form and Manner) violation, 58 included a 395.8E-HOSPD (false record of duty status) citation, and 54 included a 395.8A1-HOSP (failure to have a proper record of duty status). That pattern strongly suggests officers are using HOS record gaps or inconsistencies as corroborating evidence when writing the fatigue or illness citation.
Here's what you can do before and during every pre-trip to reduce your exposure:
- Keep your ELD records clean and current. With 82 co-occurring ELD form-and-manner violations in just 90 days, a messy ELD log gives an officer a reason to look harder at your condition. Correct any discrepancies before you pull out.
- Never drive with falsified or incomplete duty status records. Our data shows 58 same-inspection false-record citations alongside 392.2-INAT. If your paper trail doesn't match your actual hours, you've handed the officer a second violation and reinforced a fatigue narrative.
- Carry and present a valid medical certificate. 54 inspections in the last 90 days included a 391.41APC (no valid medical certificate) citation alongside this code. A missing or expired medical certificate raises immediate flags about fitness to drive.
- Ensure your portable ELD is properly mounted before departure. 56 co-occurring inspections included a violation for an ELD not mounted in a fixed, visible position. This is a quick pre-trip check that takes 10 seconds.
- Do an honest self-assessment before you start. If you're sick enough that it affects your reaction time or alertness, the regulation and the data both say stay parked. An 8-severity citation on your CSA record is a worse outcome than a late delivery.
- Check your vehicle make against enforcement patterns. Freightliner vehicles account for 2,318 all-time citations under this code — the highest of any make in our records. That doesn't mean the truck causes the violation, but it does mean officers inspecting Freightliners are writing this citation regularly. Regardless of what you're driving, your condition and your paperwork are always in scope.
