FMCSR 391.41(a) Physical Qualification – Driver Q&A

It can, but it doesn't always. Across all-time inspection records for 391.41(a), 6,861 of 42,270 citations resulted in an out-of-service order — a 16.2% OOS rate. That's actually below the all-FMCSR average of 31.4%, so most drivers cited here are not immediately sidelined. However, the recent trend is alarming: in March 2026 alone, 102 of 107 citations ended in OOS — a 95.3% rate for that month. If an inspector believes you are actively unqualified to drive, the odds of being parked on the spot go up sharply. Don't assume a low overall rate means you're safe in the moment.

391.41(a) carries a CSA severity weight of 7. That 7-point base is then multiplied depending on how recently the violation occurred: inspections within the last 6 months carry the highest time-weight multiplier, with the impact decreasing at the 6-month and 12-month marks before dropping off after 3 years. Because this code falls in the Driver Fitness BASIC, the points follow your record as a driver — not just the carrier's DOT number. A severity weight of 7 puts it in the upper half of the CSA scoring scale, meaning a single citation can move your percentile meaningfully, especially if your inspection history is thin.

Act on documentation and compliance immediately. Our inspection records show that 391.41(a) most commonly appears alongside these codes in the same inspection: operating without a CDL (383.23A2, 81 shared inspections in the last 90 days), operating while ill or fatigued (392.2FT, 42 shared inspections), and no proof of periodic inspection (396.17C, 39 shared inspections). That pattern tells you inspectors are flagging drivers who appear broadly unprepared. Right now: (1) Locate your current medical examiner's certificate. (2) Confirm your CDL is valid and the correct class. (3) Contact your carrier's safety department before your next dispatch. (4) Do not drive until you've confirmed your physical qualification status is documented and current.

It's mid-tier in enforcement volume but lower severity than its closest peers. Our database ranks 391.41(a) at #74 of 3,036 FMCSR codes by citation volume with 42,270 all-time citations. Compare that to peer codes in the Driver Fitness category: 391.41APC (operating without a valid medical certificate) has 49,539 citations and a 97.1% OOS rate, and 383.23(a)(2) (CDL wrong class) carries a 98.4% OOS rate on 50,385 citations. The 16.2% OOS rate for 391.41(a) is lower than those peers, but the underlying disqualification finding is still a serious mark in your CSA Driver Fitness BASIC that carriers and shippers can see.

Yes, you can submit a DataQs request for review (RDR), and documentation-based violations like this one are often the most contestable. If the citation was issued because paperwork was missing at the time of inspection — such as a medical certificate that was valid but not in your possession — and you can produce proof that you were physically qualified, a DataQs challenge has a reasonable basis. The process routes your challenge to the issuing agency for review. If the agency agrees the violation was issued in error or the documentation was valid, the record can be amended or removed. Gather your medical examiner's certificate, any state licensing agency records, and the inspection report number before filing.

North Carolina stands out sharply in the most recent data. In the last 180 days, NC recorded 482 citations for 391.41(a) — and 456 of those resulted in out-of-service orders, a 94.6% OOS rate. That rate is dramatically higher than the code's all-time average of 16.2%, indicating North Carolina enforcement is treating these findings as immediate disqualification events rather than documentation warnings. If your routes run through NC, ensure your physical qualification paperwork is in order and accessible before the trip, not after the stop.

Extremely urgent — and the trend data backs that up. The last 90 days produced 201 citations for 391.41(a), and the monthly trend shows enforcement has been intensifying. January and March 2026 each hit 107 citations, with 101 and 102 OOS orders respectively — OOS rates near 95% in both months. That's a sharp contrast to the code's all-time 16.2% OOS average, suggesting inspectors are increasingly treating this as a hard disqualification rather than a paperwork note. Waiting to resolve a physical qualification issue before your next dispatch is not a safe option given how aggressively recent enforcement is playing out.

Both. 391.41(a) falls under the Driver Fitness BASIC, which is one of the BASIC categories where FMCSA's SMS scoring attributes violations to the driver's own record as well as to the carrier's DOT number. That means if you change employers, the violation travels with your driving history and can affect how a new carrier is scored once you're on their roster. For fleet safety managers, this means a newly hired driver with prior 391.41(a) citations can immediately impact your carrier's Driver Fitness BASIC percentile — making pre-hire qualification verification essential.
