What Is CDL Self-Certification?
CDL self-certification is a federal requirement that took effect in 2014. Every CDL holder must tell their state licensing agency (ALEA in Alabama) what type of commercial driving they do. Your answer determines whether you must maintain a valid Medical Examiner's Certificate (MEC) on file with ALEA.
If you drive commercially and your medical certificate expires without being renewed and re-filed, ALEA will downgrade your CDL to a regular non-commercial license — which means you legally cannot drive a commercial vehicle until you resolve it.
⚠️ Important Timing Note
You must self-certify within 30 days of receiving your CDL or CLP. After that, you must keep your certification current — if your medical certificate expires, update ALEA within 30 days. Failing to do so results in automatic CDL downgrade.
The Four Self-Certification Categories
| Category | Who It Applies To | Medical Certificate Required? |
|---|---|---|
| Non-Excepted Interstate (NI) | Drive across state lines in commerce or transport HazMat requiring placards. This is the most common category for over-the-road truckers. | Yes — must file and keep current with ALEA |
| Non-Excepted Intrastate (NTI) | Drive only within Alabama for commercial purposes and are subject to Alabama's physical qualification standards. | Yes — Alabama medical standards apply |
| Excepted Interstate (EI) | Drive across state lines but are exempt from federal physical qualification standards. Rare — applies mostly to certain farm, custom harvesting, or emergency vehicle operators. | No |
| Excepted Intrastate (ETI) | Drive only within Alabama and are exempt from Alabama's physical qualification standards. Also rare. | No |
✓ Which Category Are You?
If you're an over-the-road trucker, regional driver, or any driver who crosses state lines for commercial purposes: you're Non-Excepted Interstate (NI). This is the default for the overwhelming majority of CDL holders. If you're uncertain, choose NI — it's the most common and most compliant option.
How to Self-Certify Online — Step by Step
Alabama allows self-certification to be completed entirely online. You do not need to visit an ALEA office.
Go to the ALEA Online Portal
Visit alabamainteractive.org/alea and select "Driver License Services." Have your Alabama driver's license or CDL number ready, along with the last four digits of your Social Security Number and your date of birth.
Select "CDL Self-Certification"
From the menu, choose the CDL Self-Certification option. You'll be prompted to select which of the four categories applies to you. For most drivers: select Non-Excepted Interstate (NI).
Upload Your Medical Examiner's Certificate
If you selected NI or NTI, you'll need to upload a copy of your current Medical Examiner's Certificate (the card issued by your DOT-certified medical examiner after your physical). A photo or scan is acceptable. ALEA will record the expiration date and send reminders before it expires.
Confirm and Save Your Confirmation Number
After submission, you'll receive a confirmation number. Save or screenshot this — it's your proof of filing. Your CDL record will be updated within a few business days. If your CDL was previously downgraded due to an expired certificate, reinstatement typically takes 2–3 business days after you file.
📅 Set a Reminder
Your medical certificate is typically valid for 1–2 years depending on your health status. Set a calendar reminder 60 days before your MEC expiration date — that gives you time to schedule a new DOT physical, get your new certificate, and upload it to ALEA before the old one expires. A lapse = CDL downgrade.
Medical Certificate Renewal
Your Medical Examiner's Certificate (MEC) must be renewed by visiting an FMCSA-registered medical examiner before your current certificate expires. The process is the same as your initial DOT physical:
- ✓Find a certified examiner at nationalregistry.fmcsa.dot.gov
- ✓Complete the DOT physical examination (vision, hearing, BP, urinalysis, etc.)
- ✓Receive your new Medical Examiner's Certificate (paper card)
- ✓Upload the new certificate to ALEA within 30 days via the online portal
Cost is typically $75–$150 at most occupational health clinics or urgent care centers. The examiner also submits your results electronically to the FMCSA National Registry, but you are still responsible for filing with ALEA separately.
