How long do you stay in jail if you turn yourself in for a DUI warrant in north carolina?

It depends on the amount of time you have to serve. Say for example you have 2 days to serve starting on a Friday at 7pm, you would show up and be there from 7pm till a little after 12am the next day about 5 hours. This is due to overcrowding, the type of weekend I.e holiday. You could also windup spending the full two days if its slow in the jail system. I have spoken with individuals that only spent 1 hour and 30mintes. So it all depends but from what I've been told by officers, dui instructors and individuals having to undergo the circumstances it's about 5 hours you would spend.
