A CDL issued in Indiana is valid for four years. You may renew your CDL at any BMV branch up to one year before the license expires.
To replace a lost or stolen CDL, you can visit any BMV branch and present documents that show proof of identity. Those documents can be found on the Proof of Identity tab on our Real ID webpage.
You can also replace your CDL online if your name and address has remained the same since the last time you received your CDL. If you choose to renew online you will need to provide your date of birth and Social Security number.
