I'm not telling her father right now because, unlike the past times when she'd argue with me, the crap the other night has made her believe there is cause to stop... and she's told me she will. That isn't the same way the conversation ended previous times.

I do feel a bit worried about taking her at her word, but the fact she's never really came to this realization before makes me feel better.

 

Call police.

 

I will agree with most people here and say that calling the police is the best bet. I was in a similar situation as you, where a friend would constantly drive drunk. I tried the police thing, but unfortunatly she went to a friends house so they didn't get her.....but eventually she learned her lesson. She hit a parked car on the side of the road driving drunk a few nights ago (very lucky it wasn't a person) and now she has a DUI over her head. I'm hoping this will now scare her straight.

I just don't understand how that with the strictness of DUI laws people can risk driving drunk? I'm as big of a drinker as most, but I always make sure that our group has a DD (we all take turns) or if we all get sloppy we have someone to call. Even if it comes down to taking a cab, it's a lot better than losing your license
