What would happen if you got caught running away in the atate of nj if you are 16? like police?

Answer 1

They would figure out who you are and contact your parents or guardians.

Answer 2

Like wow....... If you're a minor, chances are not much will happen.... But you might consider the minor issues of how to pay for food, shelter and all those other little niceties that your parents have been providing. There's also another little matter of the very nasty people who tend to lie, cheat, steal, abuse, hurt and otherwise abuse runaways -- which unfortunately is not a comic book story, but something that often really happens.
