Show message box when the user

Currently we show a warning box with a message when drive gets submitted with wrong or empty signature (see picture below)

But this (yellow) box will not appear when the signature is correct. I thought that it would be a good idea to add the green confirmation box which informs the Driver that a drive was verified successfully, besides the regular green/gray box which indicates if drive was submitted to server.
