DOT Physical Requirements and Medical Certification Changes for 2026

The Med Card in Your File May No Longer Be the Proof

For decades, the DOT physical produced one tangible thing: a paper Medical Examiner's Certificate, the "med card," that the driver carried and you filed. If an auditor asked whether a driver was medically certified, you pulled the card.

In 2026, that paper card is quietly losing its status as the official record. The exam your drivers take is the same. What changed is how the results travel, where they're stored, and what counts as proof. For CDL drivers, the answer is no longer the card in the folder. It's the data on their driving record.

This is the National Registry II (NRII) transition, and it changes how you document medical certification in your driver qualification files. Here's what actually changed, the deadlines that matter, and what you need to do.

First, What Did NOT Change

The DOT physical itself is unchanged. The medical qualification standards under 49 CFR 391.41 through 391.49 are exactly what they were. A certified medical examiner still evaluates the same things:

• Vision (at least 20/40 in each eye, with or without correction, and a 70-degree field)
• Hearing (the forced-whisper or audiometric standard)
• Blood pressure and cardiovascular health
• Diabetes and blood sugar management
• Respiratory and neurological function
• Use of medications that could impair driving

The certificate is still valid for a maximum of 2 years, and drivers with conditions like hypertension, insulin-treated diabetes, or a vision or hearing waiver may receive a certificate valid for 1 year or less. Drivers must still be examined before they start driving and whenever a condition could affect their ability to operate safely under 391.45.

If you understand the DOT physical today, you understand it in 2026. The change is administrative, not medical.

What DID Change: National Registry II

The Medical Examiner's Certification Integration rule, the heart of NRII, shifts medical certification from a paper-and-mail process to a direct electronic pipeline. FMCSA published the rule back in 2015, but after several extensions, compliance was finally required as of June 23, 2025.

Certified medical examiners have long been required to report exam results to the FMCSA National Registry by midnight (local time) of the next calendar day following the examination. What changed on June 23, 2025, is what happens after that report:

1. FMCSA now transmits the results. For CDL and CLP holders, FMCSA electronically sends the examination results and any medical variance information from the National Registry to the State Driver Licensing Agency (SDLA), which posts the driver's medical certification status to the CDLIS motor vehicle record (MVR).
2. CDL drivers no longer hand a card to the state. Medical examiners are no longer required to issue the paper Medical Examiner's Certificate (Form MCSA-5876) to CDL and CLP holders, and those drivers no longer submit it to their SDLA. The state gets the data straight from FMCSA.
3. The MVR becomes the source of truth. For a CDL driver, medical certification status now lives on the driving record. The paper card is, at best, a temporary courtesy copy.

The exam, the examiner, and the medical standards are the same. The reporting path and the record of proof are what moved.

The 2026 Deadlines That Matter

FMCSA knew the data would not flow perfectly on day one. As of late 2025, 42 states and the District of Columbia had implemented NRII while eight had not, and even in compliant states there can be a lag between a driver's exam and the result reaching the MVR. To keep drivers on the road during that lag, FMCSA has issued a rolling series of waivers, now a six-month exemption, that let a paper MEC serve as proof of certification for up to 60 days after it is issued.

Here is the part fleet managers miss: that 60-day limit applies the whole time. The dates below are successive extensions of the same allowance, not a shift from "unlimited" to "limited."

• Through April 10, 2026: A waiver lets drivers and carriers rely on a paper MEC as proof for up to 60 days after issuance.
• April 11 through October 11, 2026: A six-month exemption continues the same up-to-60-days allowance.
• After October 11, 2026: FMCSA has stated it does not anticipate granting further nationwide NRII waivers or exemptions. Once the exemption lapses, the electronic record on the MVR is the proof for CDL and CLP holders.

Two exceptions are worth flagging. Non-CDL CMV drivers (interstate drivers who don't hold a commercial license) are not part of the CDLIS pipeline, so their paper Medical Examiner's Certificate still goes in the DQ file the way it always has. And in states that have not yet implemented NRII, examiners should keep issuing a paper MEC and drivers may still need to provide it to their SDLA. The examiner reports the results to the National Registry either way.

What This Means for Your DQ File

This is where the change lands on your desk. Section 391.51 still requires you to keep proof of medical certification in every driver's DQ file. What counts as that proof now depends on the driver.

For CDL and CLP drivers: Don't rely on the paper card alone. Confirm medical certification status by pulling the driver's MVR and checking that the record shows the driver as certified with a current expiration date. The MVR you already pull for the annual review under 391.25 now does double duty as your medical certification proof. Keep a copy of the MVR showing the certified status in the file, and watch the expiration date the same way you always have.

For non-CDL CMV drivers: Keep filing the paper Medical Examiner's Certificate under 391.51. Nothing about your process changes for these drivers.

The practical risk during this transition is a timing gap. A driver passes a physical, but the result takes days to reach the MVR. The paper card covers that gap, but only for 60 days after it was issued, and only while the exemption is in effect. If you lean only on the MVR you might see a stale date for a driver who is actually current; if you lean only on an aging paper card, it may already be past its 60-day window. Through the transition, check both and document what you relied on.

Your 2026 Action Checklist

1. Confirm your examiners report to the National Registry. Use the National Registry to verify that the medical examiner who signs your drivers' physicals is certified and reporting electronically. An exam from an unlisted examiner does not count.
2. Pull MVRs to confirm certification status. For every CDL driver, verify that medical certification appears on the driving record with a current date. Make this part of your existing annual MVR review.
3. Update your DQ file process by driver type. CDL drivers: MVR is the proof. Non-CDL drivers: paper card stays in the file. Write this distinction into your recordkeeping procedure so nothing falls through.
4. Mind the October 11, 2026 date. The paper-card allowance runs on a temporary exemption that expires then, and FMCSA does not anticipate extending it again. After that, the MVR is your proof for CDL drivers. If your only proof is a paper card, fix it before then.
5. Track every medical card expiration. None of this changes the most common violation: an expired DOT physical. Whether the proof is a card or an MVR entry, the expiration date is what gets you cited under 391.41 and 391.45.

Don't Let the Record Move Without You

The carriers that struggle with NRII won't be the ones who disagree with it. They'll be the ones who kept doing exactly what they always did, filing the card and moving on, until an auditor asked for proof of a CDL driver's certification and the only thing in the folder was a piece of paper that no longer counted.

The fix is the same discipline that keeps the rest of your DQ files clean: know what document proves what, by driver type, and track every expiration before it lapses. The same MVR you pull for the annual review is now your medical certification proof, so the work is less about doing more and more about documenting the right thing.

Core Compliance tracks the medical certificate expiration date whether your proof is a paper card or an MVR entry, alongside all 14 DQ file document types, with automated expiration alerts so a lapsed physical never becomes an audit finding.
