Seattle DUI Penalties (Gross Misdemeanor & Felony)

Most DUI offenses in Washington are charged as gross misdemeanors under RCW 46.61.502 and 46.61.5055. However, penalties increase significantly based on:

  • Prior DUI convictions within 7 years
  • Whether the BAC was 0.15 or higher
  • Whether a breath or blood test was refused
  • Whether the case qualifies as a felony DUI

Washington DUI sentencing includes mandatory minimum penalties. Judges cannot suspend certain portions of jail time.

Why Early Legal Action Matters

DUI penalties escalate quickly with prior history. In addition to criminal sentencing, a separate administrative license suspension process begins immediately after arrest.

Challenging the stop, testing procedures, and prior conviction classification can significantly impact sentencing exposure.
