Alright. I'd also like to know information  NA or NI. what else should I know if I get NA or NI as my driving type?
You will need to send a photocopy of your USDOT Medical Examiner's Certificate  to the Medical Certification Unit, prior to the expiration date of the USDOT Medical Examiners Certificate on file with DMV.
will there be any problems if my info is not current?
You could lose your commercial driving privileges if you don't have your updated information with the DMV.
