What 391.41A-MCPC means in plain language
This citation comes down to one core issue: at the time of inspection, something about your physical condition or qualification status didn't satisfy the federal requirements that govern who is permitted to operate a commercial motor vehicle. That can cover a surprisingly wide range of situations — from a lapsed or missing medical examiner's certificate to an underlying health condition that affects your fitness to drive.
The regulation sets a baseline standard that every CMV driver must meet before getting behind the wheel. It isn't about whether you feel fine that morning. It's a formal, documented standard that inspectors evaluate against specific criteria. If the paperwork isn't in order, or if there's a documented physical condition that disqualifies you, the citation follows regardless of how many miles you've driven without incident.
Importantly, this isn't a one-size-fits-all violation. The code 391.41A-MCPC specifically relates to general physical qualification under the motor carrier passenger-carrying (MCPC) context, which means inspectors applying it are looking at whether you meet the physical standards required for the type of operation you're running at that moment.
What our enforcement data actually shows
Across our inspection database, 391.41A-MCPC has accumulated 30,779 all-time citations, ranking it #95 out of 3,036 FMCSR codes by citation volume. That puts it firmly in the top 4% of all cited codes — this is not an obscure technicality. Enforcement is active and consistent.
Over the last 12 months alone, our records show 9,406 citations issued under this code, and 1,199 of those came in just the last 90 days. The monthly trend data tells an interesting story: citations spiked to 1,400 in May 2025 before gradually declining through early 2026, settling around 513 in March 2026. That pattern suggests periodic enforcement surges, possibly tied to targeted inspection campaigns.
On out-of-service outcomes: the all-time OOS rate for 391.41A-MCPC is 14.4%, meaning 4,435 out of 30,779 citations resulted in a driver being placed out of service. That's notably below the all-FMCSR average OOS rate of 31.4%, which tells you that most of the time a citation is written, the driver is allowed to continue — but "most of the time" is not "always," and 14.4% still represents thousands of drivers who were pulled from service entirely.
One more number worth sitting with: the code is OOS-eligible under certain circumstances, and even when OOS is not applied, the citation still feeds directly into your CSA Driver Fitness BASIC with a severity weight of 7. That affects your record, your carrier's record, and potentially your employment.
Who gets cited most
Looking at the last 180 days of our inspection records, New Jersey leads all states with 590 citations under this code, followed by Pennsylvania with 389 citations and Puerto Rico with 198 citations.
The OOS rate variation across these three is striking and worth understanding. In New Jersey, 449 of those 590 citations — a 76.1% OOS rate — resulted in drivers being placed out of service. Pennsylvania, by contrast, shows a 1.8% OOS rate on 389 citations, meaning almost no one was pulled from service there despite similar citation volume. Puerto Rico sits at 0.0% OOS on 198 citations. The gap between New Jersey's 76.1% and Pennsylvania's 1.8% is enormous, and it reflects real differences in how individual enforcement officers and state programs apply OOS authority under this code. If you're running through New Jersey, the odds that a 391.41A-MCPC citation ends your day are far higher than in most other states.
Among carriers, our data shows fleets such as Federal Express Corporation (USDOT 86876) with 86 all-time citations and United Parcel Service Inc (USDOT 21800) with 25 citations appearing at the top of citation counts. High-volume carriers with large driver populations naturally accumulate more citations across all codes, and these numbers reflect that scale rather than any particular pattern of non-compliance.
How severe is this compared to similar codes
Within the Driver Fitness category, 391.41A-MCPC's 14.4% OOS rate looks relatively low when you place it next to its peer codes. Consider 391.41APC — cited for operating a property-carrying vehicle without a valid medical certificate — which carries a 97.1% OOS rate across 49,539 all-time citations. That means nearly every driver cited under that code gets pulled from service immediately. Similarly, 383.23A2-LCDLN, which covers operating a CMV without possessing a valid CDL, shows a 98.6% OOS rate across 47,123 citations.
The related code 391.41(a) — also labeled as physical qualification general — has accumulated 42,270 citations at a 16.2% OOS rate, which is close to the 14.4% seen on 391.41A-MCPC. That similarity makes sense given the overlapping subject matter. The takeaway for fleet managers: the broader medical certificate and licensing codes are near-automatic OOS events, while the general physical qualification codes sit in a lower OOS tier — but still generate significant CSA weight on every citation.
How to avoid it
The co-occurring citation data from our last 90 days of inspections is the most practical guide to prevention available. In 314 inspections where 391.41A-MCPC was cited, inspectors also wrote up 396.17C-PI for no proof of periodic inspection — meaning vehicles being operated without proper maintenance documentation are disproportionately involved. In 157 shared inspections, 383.23A2-LCDLN appeared alongside, indicating drivers with physical qualification issues also had CDL documentation problems in the same stop.
Here's what drivers can do before every trip:
- Carry your current medical examiner's certificate and verify it hasn't expired. If your medical card is within 90 days of expiration, schedule your exam before it lapses — not after.
- Confirm your certificate reflects any updated medical conditions or waivers. A condition that developed since your last exam but wasn't reported is the exact gap this citation targets.
- Check that your CDL and medical documentation are consistent. Our data shows that in 157 recent inspections, an uncredentialed CDL issue appeared in the same stop — don't give an inspector two problems to write up.
- Review the vehicle's periodic inspection record before departing. With 314 co-occurrences involving missing proof of inspection, inspectors who find one documentation gap tend to look harder for others.
- If you operate Ford, Freightliner, or International equipment — which account for 5,987, 2,671, and 1,881 all-time citations respectively under this code — recognize that these platforms dominate the citation landscape, likely because of their prevalence in commercial fleets. Standard pre-trip discipline applies regardless of make, but know that inspectors encounter these vehicles constantly and are practiced at checking compliance on them.
- If you're dispatched through New Jersey or Michigan, be aware that OOS rates under this code in those states run at 76.1% and 62.6% respectively. A citation there is far more likely to end your day than the national average suggests.
