Automated photo enforcement and statutory authority in Washington
Under RCW 46.63.170, all motorists approaching a circular red signal or red arrow must bring their vehicle to a complete stop before entering the crosswalk or intersection. Automated photo enforcement permitted in cities; treated like parking infractions.
Where automated photo enforcement operates, notice of infraction is mailed to the registered vehicle owner based on automated camera images. In contrast to officer-initiated stops where the driver is directly identified and handed a summons, photo citations in Washington focus on registered ownership. Most municipal programs require local courts or administrative review tribunals to review photographic evidence prior to issuing a citation.
