Actually that was not the case for me. I pulled my own NDR as I have had 2 suspensions and wanted to see what the airlines would. It showed one from 8yrs ago (my 2nd) and one from 15yrs ago (my 1st).

The NDR as I understand it is more of a pointer directory. All it says is that a driver has a record of suspension/revocation/serious incident in a "specificed state" and nothing more. My NDR points to the states where my suspensions occured but says nothing about the circumstances only to contact that state for further details.

I could be wrong but I think NDR records are permanent. Actually I hope I am wrong as it would be nice to finally have my mistakes behind me.

Cheers
