What 391.41(a)-FPC means in plain language
When you receive a 391.41(a)-FPC citation, an inspector has determined that you do not meet the physical qualification requirements necessary to operate a commercial motor vehicle. This is a medical and fitness determination, not a behavioral violation.
Physical qualification requirements are set by federal regulation and include vision, hearing, cardiovascular health, diabetes control, and other medical conditions that could affect your ability to safely operate a CMV. The inspector may have observed indicators during the inspection—such as difficulty seeing clearly, signs of fatigue, or medical information you disclosed—that suggested you did not meet these standards at the time of inspection.
This citation is serious because it directly addresses whether you are medically fit to be behind the wheel of a commercial vehicle. It is not about your driving record or vehicle condition; it is about your physical and medical status.
What our enforcement data actually shows
Across our 13 million+ inspection records, we have documented 1,338 all-time citations for 391.41(a)-FPC. In the last 12 months, enforcement volume was 221 citations, and in the last 90 days, 7 citations were issued. This code ranks #639 out of 3,036 FMCSR codes by citation volume.
The most striking feature of this violation is its out-of-service rate. Of the 1,338 all-time citations, 1,278 drivers were placed out of service—a 95.5% OOS rate. By comparison, the all-FMCSR average OOS rate is 31.4%, meaning this code is far more likely to result in immediate removal from service than the typical violation. When an inspector cites 391.41(a)-FPC, they are almost always removing you from the roadway immediately.
In the last 12 months, the trend has been volatile. Citations peaked in July 2025 with 47 citations (46 OOS), and have declined significantly in recent months—only 4 citations in March 2026, 3 in February, and 2 in January. This suggests seasonal or cyclical patterns in enforcement activity or in underlying conditions.
Who gets cited most
Our inspection records show the geographic distribution is concentrated in a small number of states. In the last 180 days, North Carolina led with 15 citations, all resulting in out-of-service orders (100% rate). Pennsylvania had 1 citation, also resulting in an out-of-service order. No other state appeared in the top enforcement list for this specific code in that period.
By carrier, our data shows fleets such as CRIS Transportation LLC (USDOT 4048350) with 4 citations, TRES AMIGOS LANDSCAPING (USDOT 3986538) with 4 citations, and ERIC BROADWATER (USDOT 3266908) with 4 citations across all-time records. These represent small numbers in the context of fleet operations and should not be construed as patterns of negligence; they reflect individual incidents captured in roadside inspection data.
How severe is this compared to similar codes
This code exists within a category of driver fitness and qualification violations. Comparing it to peer codes provides important context:
383.23(a)(2) — CDL wrong class has 50,385 all-time citations with a 98.4% OOS rate. That code addresses operating a CMV with a CDL of the wrong class, and is far more frequently cited.
391.41APC — Medical Certificate has 49,539 all-time citations with a 97.1% OOS rate. This code addresses missing or invalid medical certificates and is also more common, though its OOS rate is similar to 391.41(a)-FPC.
391.41(a) — Physical qualification general (the parent code without the FPC variant) has 42,270 citations with a 16.2% OOS rate. This shows that the broader physical qualification category has a much lower OOS rate, suggesting that the FPC variant—which typically involves commercial driver fitness—is enforced more stringently and results in immediate removal from service at a much higher rate.
The 95.5% OOS rate for 391.41(a)-FPC reflects the critical nature of this violation. Inspectors do not issue this citation lightly; when they do, removal from service is the norm.
How to avoid it
Preventing a 391.41(a)-FPC citation requires proactive health and fitness management:
-
Maintain your DOT medical certificate. Ensure your medical card is current and that you have passed the required medical examination. Before each inspection, verify your card is valid and accessible. Medical certification is the foundation of your qualification to operate a CMV.
-
Know your medical status. If you have conditions that could affect your fitness—vision problems, hearing loss, cardiovascular issues, diabetes, or sleep disorders—work with your healthcare provider to manage them. Do not operate if you are aware you do not meet qualification standards.
-
Monitor for fatigue and illness. Our inspection records show that operating while ill or fatigued co-occurred with 391.41(a)-FPC citations in the past 90 days. Before you start your shift, assess your physical condition. If you are unwell or excessively fatigued, notify your dispatcher and do not drive.
-
Complete a thorough pre-trip inspection. While 391.41(a)-FPC is about your medical status, not vehicle condition, our data shows that co-occurring brake violations (393.43 and 393.40) and other mechanical issues appeared in the same inspections. A complete pre-trip may give you a chance to address vehicle problems before an inspector arrives and potentially compounds your citation count.
-
Be honest with inspectors about your health. If an inspector asks about your medical condition, vision, hearing, or fatigue, provide truthful answers. Attempting to conceal a medical condition that disqualifies you will only strengthen the citation.
-
Understand the OOS likelihood. Know that if you are cited for this violation, a 95.5% probability exists that you will be placed out of service. Plan accordingly—ensure your company knows your status, and do not attempt to continue operations if you have been removed from service.
