The severity of the penalties depends on if you have had any prior DUI convictions. There is no difference in penalties based on county location. Your first DUI, a misdemeanor, has a maximum penalty of 364 days in jail and/or a $5,000 fine. It is unlikely you will receive the maximum penalty on your first offense, however, the final penalty is based on the facts of your case.
If you are convicted of a second DUI within 7 years of your first offense, it is a mandatory 30 day incarceration period.
