King County District Court — Seattle Division
The King County District Court Seattle Division handles state-law citations issued in unincorporated King County and by Washington State Patrol on I-5 and I-90 around Seattle.
IRLJ 3.1(b)(1) lets Washington drivers contest an infraction by mail. Mail a written Hearing-by-Mail request along with your signed statement of defense, photos, and any exhibits within 15 days of the infraction. No bond is required — the judge rules on the papers:
