Im 16 and have my Driver's license here in AZ.?

Can i go out of state to California by myself so i can visit my girlfriend, or can i not cross state borders?
No becaue you will have sex and be in motion blind and can't srive back.

Really no because you not an adult and can't cross state line short a parent or parental consent. Plus the insurance requirement will most likely reqiure an adult be with you more the 25 miles from home anyway.
