I don't know what state you live in, but here's info on what happens for a first offense in my state.
Penalties for DUI in Nevada
The penalties for driving under the influence depend on whether one has had a DUI conviction within the past SEVEN (7) years. This calculation is made based on the time between the date of the prior arrest to the date of the current arrest.
CONVICTION: A person that pleads no contest, pleads guilty or is found guilty at trial is subject to the following judicial penalties:
DUI FIRST OFFENSE:
JAIL: 48 hours up to a maximum of SIX (6) months imprisonment, or, at least NINETY-SIX (96) hours of community service. The court may allow you to do community service in lieu of the mandatory jail time.
FINES AND ASSESSMENTS: A minimum of THREE HUNDRED FORTY DOLLARS ($340.00) to a maximum of ONE THOUSAND ONE HUNDRED SEVENTY-FIVE DOLLARS ($1,175.00) (fines and assessments).
SUSPENSION OF DRIVING PRIVILEGES: A criminal conviction for a First Time DUI results in a NINETY (90) day suspension of driving privileges. After FORTY-FIVE (45) days you may obtain a restricted driving license, to drive to and from work.
OTHER PENALTIES: The Court will always impose the requirement that you attend an EIGHT (8) hour course of DUI school, a DUI assessment program with a ONE HUNDRED DOLLAR ($100.00) fee if the blood alcohol is .18% or more, and a Victim Impact Panel with a FORTY DOLLAR ($40.00) fee. The court may also order a Breath Interlock Device be attached to your vehicle (at your expense) for THREE (3) to SIX (6) months.
I hope you get through this and thankfully nobody was hurt.
