Medical Certification Requirements
for Commercial Driver's License
and Instruction Permit Holders
All Commercial Driver's License (CDL) holders and Commercial Driver Instruction Permit (CDIP) holders must provide DMV
a Medical Examiner's Certificate, Form B-328
Effective May 2014, the exam can only be completed by a certified medical examiner listed on the National Registry of Medical Examiners.
You are required to submit a copy of your medical certificate to DMV.
You are required to fax your medical certification to:
FAX: (860) 263-5568
If you are non-compliant, DMV will send you a notification letter, and if you do not comply by the date given, your CDL or CDIP will be disqualified and downgraded to a Class D license.
Due to the quantity of medical certificates being received, Driver Services is currently in the process of reviewing each certificate individually. Please be sure your medical certificate is legible and the following is completed:
1. Driver's license number
2. Medical examiner's National Registry number
3. Date of exam
4. Expiration date of medical certificate
If the above information on your medical card is not legible or missing, you will receive a letter notifying you of the missing information.
Please keep the completed Medical Examiner's Certificate (B-328) with you when operating a commercial motor vehicle.
