Every commercial driver must pass a physical. Truck driver medical certification decides who holds a commercial license, and the rules governing it changed substantially in June 2025.
Those changes matter to your claim. Records that once lived on a paper card in a driver’s wallet now move electronically between the examiner, the federal government, and the state.
Below, we explain what the standards actually require, how the system closed its biggest loophole, and what a carrier must keep on file.
What Truck Driver Medical Certification Requires
Federal regulation 49 CFR 391.41 sets the standards. The list covers vision, hearing, cardiovascular disease, respiratory function, epilepsy, diabetes, psychiatric conditions, drug use, and alcoholism.
Most standards are conditional rather than absolute. A respiratory or orthopedic condition disqualifies a driver only where it is “likely to interfere” with operating a commercial vehicle safely.
Three conditions carry written pathways back. Limb loss allows a skill performance evaluation certificate under § 391.49, insulin-treated diabetes runs through § 391.46, and reduced vision in one eye may qualify under § 391.44.
Vision and hearing use hard numbers. A driver needs 20/40 distant acuity and a 70-degree horizontal field in each eye. Recognizing red, green, and amber signals is required as well.

Many pages state the standard incorrectly. Hypertension is not an automatic bar.
The regulation is narrower than that. Section 391.41(b)(6) disqualifies a driver with “no current clinical diagnosis of high blood pressure likely to interfere” with safe operation.
Guidance then grades it. Appendix A to Part 391 allows a one-year certification at Stage 1 and a one-time three-month certification at Stage 2. Stage 3 disqualifies a driver until readings fall to 140/90 or lower.
One caveat matters for any dispute. Appendix A says its criteria are “strictly advisory and do not have the force and effect of law.”
How Often Drivers Get Examined
Two years is the outer limit. Under § 391.45(b), a driver must be re-examined if not certified within the preceding 24 months.
Several conditions shorten that window. Insulin-treated diabetes and the alternative vision standard both require annual examination.
Injury triggers its own duty. Any driver whose ability to perform normal duties has been impaired by injury or disease must be examined again.
Why Doctor Shopping Got Much Harder
The old complaint was real. Drivers once sought out examiners willing to overlook disqualifying conditions, and a permissive doctor attracted repeat business.
Two rules closed most of that gap. Since , the examination must be performed by a medical examiner listed on the National Registry of Certified Medical Examiners.
The second change did more. Since June 2018, examiners must report results to FMCSA by midnight of the next calendar day. That duty covers examinations where the driver was found not qualified.
Read that last clause carefully. Consequently, a failed exam now generates a federal record, so quietly trying another clinic no longer erases the first result.
What Changed on
Certification data now flows directly to the states. FMCSA transmits examination results and restrictions from the National Registry to state driver licensing agencies.
Paper largely disappeared for CDL holders. Those drivers no longer carry the medical examiner’s certificate, and carriers no longer verify National Registry listing for them.
Conflicts resolve in one direction. Where the electronic record and a paper certificate disagree, the regulation provides that the electronic information controls.
Non-CDL drivers still receive paper. So the old certificate has not vanished everywhere, just for the drivers operating the largest vehicles.
What the Carrier Must Keep
Every motor carrier maintains a driver qualification file. Under § 391.51(b)(6), that file holds the medical examiner’s certificate or a legible copy.
CDL drivers follow the electronic route. For them, the carrier obtains the driver’s motor vehicle record from the licensing state and places it in the file.
Variances belong there too. Where certification rests on a federal medical variance, § 391.51(b)(6)(iii) requires a copy of that documentation in the file.
Georgia adds its own requirement. Under O.C.G.A. § 40-1-8, Georgia independently requires carriers to comply with Part 391, and that duty reaches trucks operating entirely inside the state.
How This Becomes Evidence in Your Case
Paperwork gaps reveal decisions. A missing certificate, an expired one, or a variance the carrier never obtained all suggest nobody checked.
Knowledge is what matters most. A company that hired or kept a driver it knew could not qualify faces exposure separate from the driver’s own negligence.
Our page on unqualified truck drivers covers the broader qualification file. Still, these records move quickly, so a preservation demand should name them specifically.
