Only if the state it is issued in has a statute of limitations on the crime itself.
no
Your criminal record is permanent. You might get your juvenile crimes sealed away, but nothing goes away on your adult record by itself. You can try to have your misdemeanor expunged from your record if you can convince the judge that you have really changed and deserve it.
Misdemeanor.
I'm not aware of any states extraditing for a misdemeanor, but the misdemeanor warrant will remain active until the individual is arrested, therefore, if you go back to the state where there is a warrant, you are subject to being arrested.
No, arrest warrants do not expire. You will have to settle it with the court. Added: In addition to that, because of the unanswered DUI, your driving privileges are no doubt suspended or revoked by the state. DMV records never "go away" and all states are linked via interstate data transfer.
No. If you are a juvenile it is not called a warrant anyway, it's a Juvenile Petition. When you turn 18 it will not " go away" until it is hear in front of a Judge. So no it will not go away
No.
No
it a way of life
Yes.
It all depends on what was the reason behind the issuance of the bench warrant. If it was a misdemeanor offense, yes, If it was af felony crime, it's a felony.
Bench warrants don't expire. And if it actually is a bench warrant it means that you've already been charged, so there is no SOL on the warrant itself even though the misdemeanor offense itself may lapse.
No you cannot and you will sooner or later get caught. Why not just go sit a day in jail for the misdemeanor and call it good at that instead of always looking over your shoulder.
