Introduction
DUI legal costs in Tennessee depend on whether the charge is a first-time offense or a repeat DUI, the driver’s blood alcohol concentration (BAC), and whether the case is resolved through a negotiated plea or proceeds to trial. Costs rise quickly when a case involves contested evidence, multiple hearings, or enhanced penalties tied to aggravating factors.
A Tennessee-specific cost driver is mandatory minimum penalties combined with license revocation rules, which apply even in some first-offense cases. These requirements often add significant expenses beyond attorney fees, including treatment programs, ignition interlock devices, and extended court supervision.
