You did the right thing.....
1.) The most likely weren't going anywhere, and needed the help anyways....
2.) and Think about this:
If they actually could have been on the road (you said that your daughter was w/ you)........no matter what they drive.........would you have wanted them risking your daughters' life?
A drunk driver killed my grandpa, and permanently injured my grandma......
I'm VERY bitter towards them.
