You are required to self-certify to a single type of commercial driving on your driver's license application form when you:
You may need to provide a valid medical examiner's certificate and show any medical variance documents you have when renewing your CDL or obtaining an original one. You can provide this to the Michigan Secretary of State by visiting any office, faxing it to 517-636-4359 or sending it online at www.Michigan.gov/CDL.
The SOS will be unable to process any of these forms if they are incomplete or illegible, and will return them to you.
