If you do not live near public transportation, you would need to explain your rules re: using your family's car etc.
Honestly, from your post, it sounds like you are going into this with a negative outlook, though. Are you sure you want to do this?
She's 15, so presumably driving is off the table.
I agree with the others that you don't want to start out discussing drug and alcohol use. If that's a big concern of yours, you could discuss it with the parents. In terms of other rules that don't really affect you/your kids (i.e. whether she stays up late playing on her phone), discuss with parents what they want you to enforce.
