I think I might be different to everyone else here and my DD is only 5 but these are the rules my parents had for me when I was 16.5:

I had a car and was allowed out on fri and sat nights but only til midnight.
I had been riding in cars with older boys/girls for about 2 years by that stage but my parents knew all my friends.
If I ever went away with them it was always in a family group with other parents.
We hung out in all sorts of places like car parks and look outs but always came home at our curfews.
Drinking - my parents let me have a few sips of theirs at a very early age so drinking was never a big deal for me. They let me drink beer and wine but refused spirits as they were too strong and I only started them when I was older.

Over all my parents had the attitude that they would rather us do things at home, like drinking and having boys over, than doing them in a park or the backs of cars where we would be in potentially a lot of danger. My parents taught me responsibility for my actions and I learnt the hard way a couple of times but never too badly.

Even though it will be hard I hope to have the same attitued with my DD, who knows, I may be very strict and she may hate it! At the end of the day it is up to you what you think is appropriate rules for your house and what you are comfortable accepting. Good luck!
