On special application and under exceptional circumstances, a license to train may be granted to an amateur rider only to train horses owned by such rider and members of such rider's immediate family, without affecting his or her standing as such rider. When so licensed as a trainer, he or she shall not be permitted to ride any other horses except those he or she trained.
