King County: Photo Enforced Tickets
Washington state law allows for photo enforcement violations to be processed like parking tickets and filed against the registered owner. A photo enforcement conviction will not appear on your driving record, but failure to respond to the ticket may affect renewal of your license plate and the case will be sent to collection.
