FMCSA's last nationwide exemption ends this month. After it does, the motor vehicle record is the only thing that proves your CDL driver is medically certified.
On October 11, 2026, FMCSA's temporary exemption for paper medical examiner's certificates expires -- and the agency has already said not to expect another one. After that date, a paper med card in your file is not proof that a CDL driver is medically certified. The motor vehicle record is. If you are still filing paper cards and calling it good, your driver qualification files are about to fail an audit you have not scheduled yet.
The Medical Examiner's Certification Integration rule -- everyone calls it NRII, for National Registry II -- took effect June 23, 2025. It rewired how medical certification gets from the exam room to your file.
Under the old system, the driver got a paper card, handed a copy to you, and separately walked or mailed a copy to the state driver licensing agency. Three places, three chances for it to go wrong.
Under NRII, the certified medical examiner transmits the exam results directly to FMCSA's National Registry by the end of the next calendar day. FMCSA passes that to the state licensing agency. The state posts the certification status to the driver's CDL record. The driver never has to deliver anything, and neither do you -- you just pull the record.
That is a better system when it works. The problem is the handoff.
Five states -- Alaska, California, Kentucky, Louisiana, and New Hampshire -- had not finished implementing NRII, so FMCSA issued a temporary exemption letting carriers and drivers keep relying on the paper certificate as proof of certification for up to 60 days after it was issued. That exemption runs April 11, 2026 through October 11, 2026.
FMCSA was direct about what comes next: states, motor carriers, and drivers should not expect additional nationwide waivers or exemptions past this one. Six months was the runway. It is almost gone.
This is the part that trips carriers up, because the answer is different depending on the driver.
Under 49 CFR 391.51(b)(6)(ii), you satisfy the medical certification requirement by obtaining the CDLIS motor vehicle record from the driver's current licensing state and putting that in the file. Not the card. The record. And the regulation is blunt about the consequence: a non-excepted interstate CDL holder without medical certification status on the CDLIS MVR is designated "not-certified" to operate a commercial motor vehicle in interstate commerce.
Read that again. Not "pending." Not "give us a minute." Not certified. A driver can pass a DOT physical on Monday and still be unqualified to drive on Friday if the certification never made it onto the record.
Nothing changed for them. Non-CDL interstate drivers still get a paper medical examiner's certificate, and a copy of that certificate still goes in the driver qualification file under 391.51(b)(6)(i). You also still need the note verifying the examiner was listed on the National Registry, which 391.51(b)(8)(i) still requires for non-CDL drivers only.
If you run a mixed fleet, you now have two different filing rules under one roof. That is exactly the kind of thing auditors find.
Not sure which of your drivers fall on which side of that line? That is a 20-minute conversation, not a project. Talk to TruckWise about your driver files.
The rule assumes a clean chain: examiner uploads, FMCSA forwards, state posts. Every link can stall.
Under the old paper system, the driver handed you proof. Under the new one, silence looks exactly the same as success -- right up until it does not.
TruckWise runs this check for our clients. We pull the records, catch the drivers whose certification never posted, and chase down the examiner or the state before the driver becomes unqualified. See how our driver and safety compliance service works.
Medical certification failures are already among the most common findings in a DOT compliance review, and NRII gives auditors a cleaner way to check. They do not have to sort through your paperwork and decide whether a photocopy is legible. They pull the CDLIS record and see a yes or a no.
An unqualified driver operating a commercial motor vehicle is a serious violation, and it compounds. It hits your Driver Fitness BASIC, it shows up in a new entrant safety audit, and it feeds directly into an unsatisfactory rating. Missing documents in the driver qualification file are already the number one finding auditors report -- see our breakdown of what belongs in a DQ file if you want the full list.

After October 11, 2026, for CDL drivers, the MVR is the record. Paper is a courtesy copy. If you have not pulled records on your whole roster this quarter, do it now -- while there is still time to fix whatever you find.
