Missouri CDL Requirements
All Missouri CDL holders are required to certify the type of commercial operation they’re engaged in.
Interstate Non-Excepted
You must meet the Federal DOT medical certificate requirements.
Intrastate Non-Excepted
You must meet the Federal DOT medical certificate requirements.
Under the federal regulations, all CDL holders are required to self certify to a single type of commercial operation. Based on that self-certification, you may need to provide a current medical examiner’s certificate and show any variance (FMCSA waiver) you may have in order to obtain or keep your CDL.
CDL holders required to have a “certified” medical status who fail to produce and keep up-to-date their medical examiner’s certificate with the Department will become “not-certified” and they may lose their CDL.
CDL retesting may not be required unless you voluntarily downgrade your license or let your CDL license remain expired for more than six months.
Submitting your Medical Certificate to Missouri License Office
When requested, submit a copy of your valid DOT medical certificate.

Safeguard your CDL! How does the new DOT Medical Certificate reporting process affect your CDL?
Non-CDL Drivers
The electronic reporting requirements do not affect non-CDL drivers.
• The medical examiner must give you a physical MEC Form MCSA-5876.
• You should keep your medical certificate available at all times whilst driving a CMV.
• You will still need to provide a copy of the MEC to the companies you work for.

My missouri cdl Medical card is expiring. Do I neeed one If never cross state line?
@ Raymond F B
Most states require a valid medical card to maintain a cdl. Best to confirm with your local DLD.
I was in a accident and can’t go back to work yet but I need to renew my driver license and I don’t have an up to date medical card. Can I renew my CDL without a up to date card. I live in Missouri
@ Dane
Probably not, but confirm with your local drivers license department. Explain your situation, they should have a process that will work for you.
I have to do physical for dot every yr and echo stress every 2. My question is when I go for my regular dot and they say I’m good but still say I need a dr. note from my heart Dr. that I’m good do drive. My medical card doesn’t expire for another week and a half and now I can’t drive till I get my heart dr to say I can still drive. Dot was gonna give me 45 day grace to get it done but my company says I can’t drive cause it voided my license since I have to have Dr note to say I’m good. Is this true. I live in missouri.
@ Larry
For a class A cdl, DOT/FMCSA. If you have not done your medical certification examination yet, then your medical card is still good and you can drive. And you will need the medical release form from your heart doctor. If you have had a recent examination and the CME is waiting for a medical release form, then you should either have a short medical card, (90 days) to get it done. If no short card, then the company is, theoretically, correct. Get the medical release form, asap, and you will be OK.
I just renewed my Missouri license CDL I dropped my hazmat because I am now retired and do not need it. I would like to keep my CDL for personal use. No commercial driving. Do I still need medical card?
@ Russ D
Confirm with your local DLD. Most states require a valid medical card to maintain a cdl.
One of my students is getting her CLP but her Med card expires in 15 days. What happens if her med card expires while holding a CLP and have not yet obtained a CDL/
@ Robert McG
It should not be an issue to get a new medical card and then have it upgraded for her cdl when she gets it.
