Every Pennsylvania CDL holder must self-certify one of 4 driving types with PennDOT: Non-excepted Interstate, Excepted Interstate, Non-excepted Intrastate, or Excepted Intrastate, using form DL-11CD. Drivers in non-excepted categories must also keep a valid Medical Examiner's Certificate on record. When that certificate expires, PennDOT mails a notice and the driver has 45 days from the mail date to update it before the commercial designation is removed. Since June 23, 2025, FMCSA transmits examination results from the National Registry to PennDOT electronically.
TL;DR: If you hold a Pennsylvania CDL, you have to tell PennDOT what kind of driving you do. There are 4 choices, and you make yours on form DL-11CD, which you can get at pa.gov/dmv. Two of the 4 choices also require a valid medical card on file with PennDOT. Here is the part that costs people their license: when your medical card expires, PennDOT mails you a notice, and from the date on that notice you have 45 days to get an updated card on file. Miss it and the commercial designation comes off your license, and you get mailed a regular one. Since June 23, 2025, the examiner sends your results to the federal registry and the registry sends them to PennDOT, so you usually do not mail the card in yourself. Do this today: find your medical card, look at the expiration date, and put a reminder in your phone for 90 days before it.
Most of the CDL rules a driver has to keep track of are about the truck. This one is about paperwork, and it is the one that takes licenses. A driver gets a physical, passes it, puts the card in the glovebox, and 2 years later a letter arrives saying the commercial designation has been removed and a regular license is on its way. Nothing went wrong medically. The card expired, the clock ran, and nobody was watching it.
What I want you to know is that the whole thing is a calendar problem with a medical component, and the calendar part is solvable in an afternoon. This page covers the 4 self-certification categories, which drivers need a medical card on file, what changed in June of 2025, and how the 45-day clock works when a card lapses. It is written for Pennsylvania because the process is run by PennDOT, though the underlying federal structure is the same everywhere.
What is self-certification, and who has to do it?
Self-certification is you telling PennDOT which of 4 kinds of commercial driving you do or expect to do. Federal regulation requires it, and the point of the exercise is to identify which drivers must keep a Medical Examiner's Certificate on file with the state.
Every driver who holds a Pennsylvania commercial driver's license has to submit one, and so does every driver applying for a commercial learner's permit. The form is PennDOT's DL-11CD, available through the Commercial Driver Information Center at pa.gov/dmv.
What are the 4 self-certification driving types?
The 4 categories come from crossing 2 questions: does your driving cross a state line, and is your operation one of the ones excepted from the federal medical certificate requirement.
| Category | What it means | Medical card on file with PennDOT? |
|---|---|---|
| Non-excepted Interstate (NI) | You drive across state lines in ordinary commercial operation | Yes |
| Excepted Interstate (EI) | You cross state lines but your operation is federally excepted | No |
| Non-excepted Intrastate (NA) | You drive only within Pennsylvania in ordinary commercial operation | Yes |
| Excepted Intrastate (EA) | You drive only within Pennsylvania and your operation is excepted | No |
Interstate commerce, in the federal definition, is trade, traffic, or transportation between a place in one state and a place outside it, or between 2 places in the same state by way of another state, or between 2 places in the same state as part of a movement that originates or ends outside the state. That last clause catches more drivers than they expect. A run that stays inside Pennsylvania can still be interstate commerce if the freight started in New Jersey or is headed for Ohio, and the driver hauling it is Non-excepted Interstate even though the truck stays inside Pennsylvania.
Excepted operations are a defined list rather than a judgment call. They include school bus drivers, certain government employees, and beekeepers, among others. If you are not sure whether your operation is excepted, that is a question for PennDOT or your carrier's safety department rather than something to guess at on a form, because guessing wrong here is what produces a downgrade later.
What changed on June 23, 2025?
Starting June 23, 2025, the Federal Motor Carrier Safety Administration began electronically transmitting examination results and restriction information for commercial learner's permit and CDL holders from the National Registry directly to PennDOT. FMCSA also transmits medical variance information for all commercial motor vehicle drivers the same way.
For a driver, the practical effect is that the mailing and faxing step mostly goes away. Your certified examiner submits the exam, FMCSA passes it to PennDOT, and your record updates. That is a genuine improvement over a system where drivers hand-delivered paper to a licensing center and hoped it got filed.
It also creates a new way to get burned. Because the transmission is electronic and happens on the examiner's end, a driver who assumes it happened has no confirmation that it did. PennDOT mails a receipt when a Medical Examiner's Certificate or self-certification form has been processed, and that receipt is worth keeping. Your self-certification driving type and medical certificate information also appear on your driver abstract, which is the document your employer sees, so pulling your own abstract is the direct way to confirm your record says what you think it says.
How does the 45-day downgrade clock work?
This is the part that costs drivers their commercial privileges, so it is worth walking through slowly.
When your Medical Examiner's Certificate reaches its expiration date, PennDOT mails you an official notice. The notice says your medical certification status has been changed to not certified and that downgrade procedures have been initiated. From the mail date on that notice, you have 45 days to get an updated certificate on record with PennDOT.

A 90-minute conversation with Dr. Ash. A written plan you can actually follow.
If a new certificate arrives inside those 45 days, nothing further happens. If it does not, the commercial designation is removed from your license and PennDOT issues a duplicate non-commercial driver's license. You are not suspended and you have not lost your driving privileges, but you are no longer a CDL holder, and getting the designation back is a longer road than renewing on time.
Three things about that clock are worth holding onto:
The clock runs from the mail date of the notice rather than from the date you open it. Mail that sits in a truck for 3 weeks costs you 3 weeks. If you are on the road for long stretches, have someone check your mail or make sure PennDOT has an address where mail reaches you.
The clock does not care why the card lapsed. A driver who was in the hospital, a driver whose examiner retired, and a driver who forgot are all on the same 45 days.
A suspension does not pause the requirement. If your driving privilege is suspended or disqualified for an unrelated reason, you still need to submit the self-certification and medical certificate, or the status flips to not certified and the downgrade begins when your privilege is restored.
What if I already got downgraded?
Getting the commercial designation restored means going back through the process rather than filing an appeal. The medical certificate has to be current, the self-certification has to be on file, and depending on how long the gap ran, there may be additional licensing steps. PennDOT's Commercial Driver Information Center is the authority on the current requirements, and the timeline is worth confirming with them directly rather than relying on what somebody at the yard remembers.
The medical side of it is where we can help, and the useful question is why the card lapsed in the first place. A card that ran out because of a missed appointment is a scheduling fix. A card that ran out because the driver knew the blood pressure reading was going to be bad and put off the exam is a medical problem wearing a paperwork costume, and it does not get better by waiting. That second case is more common than the first, and it is the one worth being honest about at the first visit.
What Fishtown Medicine does around this
Fishtown Medicine does not perform DOT physicals or issue Medical Examiner's Certificates. Only a medical examiner listed on the FMCSA National Registry may do that, and the directory of certified examiners is at nationalregistry.fmcsa.dot.gov.
What we do is the clinical work that decides how that appointment goes and how long the card lasts. That means treating blood pressure to where an examiner can write a 2-year certificate instead of a 3-month one, testing for sleep apnea before an examiner makes it a deadline, managing blood sugar, and keeping your records organized so the specialist reports and treatment documentation are ready to hand over. The CDL and DOT driver health page covers what to work on and how far ahead to start.
For drivers running regional or long-distance freight, Dr. Ash is licensed across 39 states plus DC and Guam, so the care continues when the route leaves Pennsylvania. That matters for a population that often has no employer health plan and no doctor who knows them, and it means a medical problem found in Indiana does not have to wait until you are home.
Key Takeaways
