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 21, 2014, the exam can only be completed by a certified medical examiner
listed on the National Registry of Medical Examiners.
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.
Driver Services is currently in the process of reviewing each certificate individually. Please be sure your medical certificate is legible and is completed in full.
If the any information on your medical card is not legible, incorrect or missing, you will receive a letter notifying you that you must re-submit a new medical card.
Please keep the completed Medical Examiner's Certificate (B-328) with you when operating a commercial motor vehicle.
