It depends on what state you live in, but I highly doubt you will get jail time as a first time offender. I had a DUI about 12-13 years ago and had to pay a fine, attend classes/AA and do community service work. Where I live, they allow you to drop a first DUI offense for insurance purposes (law enforcement can still see it), but if you get another one, the first counts. It's very scary but be thankful no one was hurt. Hang in there.
