Is there ‘not so good’ news?
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.

I have a cdl but I have not had a medical exam for 4 years. I need to renew my license. Can I have a exam and renew my license and retain my cdl? Thank you.
@ Randy L
Go get the medical and take your results straight to your local drivers license department. That way, if they have downgraded your cdl, they see that you are trying to be compliant.
I have a CDL that expires in 2024, but my Med card expired in May 2022. If I renew my Med card, is my CDL still valid until the 2024 expiration date?
@ Manny
Yes.
Can patients see their PCP who is also a CME? Or do they have to see a different CME who doesn’t know the patient because the PCP could be biased?
@ Savannah
If your PCP is a CME, then by all means use him/her.
i thought i had another month to renew my dot but it expires today. is there a grace period in mt or will i perminintly loose my cdl, especially if im not driving?
@ Nicole M
DOT/FMCSA has extended the grace period until the end of August. So you have some time, still recommend you get it done ASAP.
If a Montana cdl driver fails his or her dot physical do they still have to pay for it. Also who wrote the law of no nicotine before a dot physical.
@ Shane
Yes, you pay for the examiners time and talent, not a test. There is no law about no nicotine before testing, but it does keep blood pressure down.
Hi, I was wondering if you know how long a new driver for a CDL has to be on a CPAP machine in order to pass the DOT medical if they are just starting treatment.
Thank you
@ Sarah
30 day minimum and 90 day at the most, with a 30 day readout demonstrating a 70 % compliance.
I’m trying to check to see if you received my new DOT physical form Dr Matt Stanley for Candi B drivers license number ___.
@ Candi B
Contact your local drivers license department for this information.
What is the email address to email my Medical form and Medical Card
@ Adam
Check with your local drivers license department for their process.
