Yes, i want to do that.
That's ok. You'll be complying with the new federal regulations that require from all commercial drivers to certify to DMV the type of drive they are performing.
Ok, thanks. In that regard, my CDL was recently downgraded because that lack of certification in my medical situation, can i have it back as it was before?
Yes, you can. You'll need to visit a local DMV office in order to upgrade back.
