Wash. Admin. Code § 260-28-210
If a trainer will be absent from the track where his or her horses are participating in races, the trainer must first obtain a licensed trainer to substitute for him or her during the trainer's absence. The substitute trainer must be approved by a steward prior to the original trainer's absence. The original trainer remains the absolute insurer of any horses he or she has entered. Once a substitute trainer has been approved by a steward, the substitute trainer will then become the absolute insurer of any additional horses he or she may enter.
