Accident causer alcoholized – who pays?

Hello together and apologizes for my stupid question, but I’m kind of not quite sure and I’m afraid the worst. The following: Grandma drives on my road and “only” drives off my Beby (A5) the mirror (somehow the door must also be warped, because it whistles in the drive from all cracks), because I have still evaded on the green strip (at about 100 km/h). I directly turned around, afterwards. Police did not see the accident directly, but the woman directly h after 2 km she stops, of course, too. Alcohol test – more clearly over 1.5 on the box the good woman. Was also reported to the police by several other drivers before (road danger). So the good lady was clearly alcoholic.Now the question: Does her liability pay in this case? From whom do I get the money again? Who do I have to turn to now? Thank you for the help in advance.
