In a 5-4 case, the United States Supreme Court ruled that a warrant is not generally needed to draw blood from an unconscious person suspected of DUI. In the case of Mitchell v.

Tennessee DUI laws provide mandatory minimum sentences, and sentence enhancement factors, for those who are convicted. A DUI first offense carries a minimum sentence of 48 hours in jail and a $350.00 fine, among other things. This minimum sentence however can be increased in several ways. For example, if your blood alcohol level is 0.20% or higher, the minimum sentence is raised to 7 days, even on a first offense. For those charged with DUI with a minor in the vehicle, the minimum jail time is substantially increased to 30 days. Read on to understand the different sentence enhancements and criminal charges that can be brought against you.
