CDL medical card renewal timeline (DOT / FMCSA)
Last reviewed 2026-09-19. Not legal advice — confirm fees, hours, and forms on the official .gov page before you file. Rules change.
The plastic CDL in a driver’s wallet is not the credential that usually takes them off the schedule. The DOT medical examiner’s certificate — often called the medical card — is. Federal rules cap it at 24 months. Many drivers are on 3-, 6-, or 12-month cards. If the state driver license agency does not have a current certificate, commercial privileges get downgraded even when the license photo is still in date.
The federal rule in one paragraph
A Department of Transportation physical must be performed by a medical examiner listed on the FMCSA National Registry. If the driver is physically qualified, the examiner issues a Medical Examiner’s Certificate (MCSA-5876) and completes the longer Medical Examination Report (MCSA-5875). FMCSA’s published maximum validity is 24 months. Examiners issue shorter certificates when they want to monitor blood pressure, sleep apnea, diabetes, vision, or other conditions.
There is no “CDL medical CE.” There is a new exam before the printed certificate expires. Federal exemptions (vision, diabetes) are a different, often annual, process with FMCSA — not the same as a routine 2-year card.
Typical timeline (work backward from expiry)
Day 0: exam date printed on the certificate. That is the start of the term, not the CDL birthday.
Day 1–540 (about 18 months on a 24-month card): keep a copy in the driver qualification file. No action unless the examiner set a shorter card.
60 days before expiry: book a National Registry examiner. Do not use a walk-in clinic that is not on the registry. Texas DPS, as one example, mails a courtesy notice about 60 days out; other states vary. Courtesy mail is not a system.
30–45 days before expiry: complete the physical. Electronic National Registry II reporting (phased in through 2025–2026) sends results to the state. Still verify the state record updated — California historically required MER/MEC on file with DMV; Texas now expects NRII posting and will downgrade on day 60 after a required medical expires.
Expiry day: stop dispatching the driver in a CMV that requires a CDL if the certificate is required for their self-certification. A wallet card that the state has not posted is not enough.
After expiry: states downgrade commercial privileges on their own clocks (Texas: 60th day). Getting privileges back can mean an office visit and, in the worst case, retesting. That is a tracking failure, not a medical mystery.
Self-certification categories (why some drivers skip the card)
CDL holders tell the state whether they operate interstate or intrastate and whether they are excepted from medical certification. Non-excepted interstate drivers must maintain a certificate. Excepted and some intrastate categories follow different posting rules. Copying one interstate driver’s file onto every driver on the roster is how shops over- or under-track.
School bus (19-A in New York), passenger, and some state-restricted CDLs add extra medical forms. Those are not a substitute for the FMCSA certificate when the federal category requires one.
What to put in the tracker
Two dates per driver, always: CDL document expiration and medical certificate expiration. Add a third date if you operate in a downgrade state (medical expiry + state downgrade days). Add endorsement rows for hazmat (TSA), TWIC, and passenger.
Shorter medical terms should be visually louder than 24-month terms. A driver on a 3-month card is a weekly operations problem, not a “renewals someday” problem.
How this ties to OSHA and licenses
OSHA 10/30 does not renew a medical card. A current SST card in New York City does not either. Contractor licenses (CSLB, CILB, TDLR) are a different calendar. If one employee is a CDL driver and a licensed electrician, they need both files.
FAQ
Does a CDL medical card expire every 2 years?
At most every 24 months. Many certificates are shorter. Read the date on that driver’s MCSA-5876.
Does the medical card expire when the CDL expires?
No. The CDL and the medical certificate are different documents. The medical card usually expires first.
Who must perform the exam?
A medical examiner on the FMCSA National Registry — MD, DO, PA, APRN, or DC as allowed by FMCSA — not an arbitrary clinic physical.
Is this legal advice?
No. Confirm current FMCSA and your state DMV/DPS/FLHSMV rules before you dispatch. This is an operations timeline for US carriers and contractor fleets.
