Let me try and throw in my $.02
When I was 23, I got charged with a DUI. I'm one of those people that was opposed to excessive drinking, let alone drinking and driving. But every case is different. To all those who are bashing people for getting a DUI, I hope you don't get stuck in a bad situation yourself.
In my situation, I hadn't had a drop of alcohol for over a year up to a few months before the arrest. I had started a business with a partner that required me to go into bars quite a bit. My business partner thought it was a useful tool to network with the owners and managers of these bars by having a beer or two (which, sadly, is the case). In the case that night, I was at a customers bar. The bouncer didn't know me and ID'd me and gave me a wrist band. I did my "networking" and left to go to a buddies house. I decided to take the back way just to avoid traffic.
When I went over a bridge my back right tire blew out and I lost control. Thankfully, no one was injured. The city police showed up and were prepared to let me get a ride with the tow truck. Then a state trooper arrives and sees my wrist band. He thinks I'm some spoiled kid in a sports car (which I payed for) and gives me sobriety tests. I pass them all. Then puts a flashlight in my eye and calls over his partner to look. They both agree that my eyes lagged behind the light and arrested me.
I wasn't sure what to do as far as blowing, and they wouldn't let me call a lawyer. When I get to jail, one of the guards advises me not to blow, so I don't.
I lost my license for a year because of that decision. Eventually, I ended up with a no contest to reckless driving. That accident and everything else with it ended up costing me $50,000. Some because I totalled my car, some for the lawyer and court fees, but most from lost wages because I couldn't drive, which was a must for the business. Thankfully, I have my license back and have moved on, but it doesn't take much to remind me of the price I paid for that one night.
So for everyone on here painting a blanket statement over anyone who has been arrested for a DUI, I encourage you to reconsider. In the mandatory class I took with other DUI people, most of them were just normal people who made a horrible, horrible decision. They weren't monsters.
To the OP, you're in for an uphill battle. Get a good attorney and make sure to follow through on anything the court tells you. Learn from this mistake and uderstand that it doesn't define you as a person, it just defines one decision you made. Just make better decisions from now on. Good luck.
