Only 15 days and I'll be bringing our little girl home!

We live in a rural area with a small garden which immediately continues on into vineyards - we get foxes and other wild animals passing through the garden every night. So... plenty of space for the pup, but there's a catch: we can *not* close off our garden, due to a right of passage for our neighbour.

On the other side of the house, there's a long driveway leading up to the street, also through the vineyards. It'll take her some time to get there (I could even temporarily close off the access to it, though not by any means that would stop a determined puppy), and obviously we won't let her wander around on her own, but my biggest fear is her sneaking away to explore, ending up on the street and getting overrun by a car. 

While we will (again, obviously) try to prevent this in any way possible, I know from experience with my parents' dogs that no matter how careful you are; or how strong your fence is, some day, your dog is bound to make it out on his own... My parents' dogs jumped up onto the roof of their dog house once, and from there over a high sharp wooden fence more than a meter away from it (had they come up 30 centimetres short, they would have impaled themselves on it). Then, they ran off into the sunset... and under the wheels of an upcoming car.

Thankfully, the car had had the time to slow down, so no real damage was done, except for two very scared dogs under a bush. They wouldn't let anyone but my mother approach them, and then after a check-up at the vet, they slept for 2 days straight.

This experience is probably why I'm so worried about it... But how can I train my puppy to be careful, should she ever find herself on the road without me or my husband to keep her safe? I've seen other dogs get into harms' way, so I know instinct is not enough.
<bot>: Sorry this got long and wasn't very to the point, I'm just wondering how I can teach her to be careful, and to recognise a road for what it is, no matter where she encounters one.
