I plead guilty to reckless driving after being arrested for dui. I received 1 year probation, with possible early termination I should be done with all requirements a month or so in. how early could I possibly be released?

You need to do all your requirements and have at last 1/2 to 3/4 of your probation successfully completed. Then ask your probation officer for a possible early termination. You may or may not get it as the probation officer must ask the Judge and present the paperwork for the Judge to sign the Order of Termination. The paperwork sometimes take awhile, so possibly the probation officer will explain that you would be off probation on your own sooner than if you waited for the Judge to okay it. You can still ask the PO anyway as your county may not be so backed up in the Courts and actually get off a month or so early.
