Tough to say what's gonna happen in your state. In Washington, First Offense isn't too bad. You'll go, get a alcohol evaluation, and show that to the judge when you return. He'll make his decision based on that evaluation. That doesn't mean you'll get off. Be prepared to pay bro. It's not whether or not you pay, but how much at this point. I had my First DUI knocked down to a Negligent Driving in the First degree. I recieved no AA's or Treatment.
However, later down the road I had a couple beers(really, only two) and I spun the tires on my truck in a parking lot. That caused another negligent in the first.
Later on(do you see the pattern here?), I ended up in front of the same judge for fighting at a party. Using his discretion, he sent me in for another EVAL and said if I came back with a clean slip he wanted the counselor in his courtroom to tell him why I didn't have a problem.
I did a year of treatment. Just don't drink and drive. I figured out that over the last seven years, those incidents have cost me over $7000. That money would have bought every taxi ride I ever wanted to take. If you think you can't afford a taxi, then you shouldn't leave the house.
Far from perfect, I'm giving you words of advice. OK, I would go to preliminary hearing and see how bad the evidence is. Sounds fairly bad. If you can't afford a great lawyer, don't buy one. Get the court appointed attorney or defend yourself. "Only a fool....." They never had a court appointed attorney. What you are shooting for is to go deferred. The fine will be lower, and if your good for a disclosed amount of time(x years), then the ticket drops off of the record that most people see. (I did this, but the judge and cops ALWAYS see this record, until you die.)
Good Luck man, I feel your pain. Hopefully you don't do it again. Second offenses are serious jail time and huge fines. Loss of License is a big issue too.
