No. If your name is on the ticket but it's not your face in the photo, you don't have to identify the person driving. For more info on how to handle this situation, go to the "It's Not Me!" section on the Your Ticket page.
No and if they find out who it is, these are one of the easiest tickets to beat - I'm assuming you are friends with the driver - he can fight it on his own - there is plenty out there on the internet.
