Introduction
DUI legal costs in Washington depend on whether the charge involves a first-time offense or repeat violation, the complexity of evidence, and whether the case resolves through negotiation or proceeds to trial. Legal expenses increase when cases involve contested breath tests, accident investigations, or extended court proceedings requiring expert witnesses.
A major Washington-specific cost factor is the state’s mandatory administrative license process and ignition interlock requirements, which often create parallel expenses outside the criminal case. These additional compliance steps can significantly raise total DUI costs even when the underlying charge appears straightforward.
