Idaho Admin. Code r. 02.08.01.103
Sheep and goats in course of transit through the state of Idaho, in trucks, or other vehicles from a point outside the state of Idaho to another state or country, are not to be unloaded in Idaho except in pens designated by APHIS for purpose of feed, water and rest for a period of time not to exceed ten (10) days, need not comply with Section 100, provided waybills or other documents accompanying the sheep or goats show origin and destination of such sheep and goats. Failure to have such waybills or other documents with the sheep or goats constitutes a violation of these rules. The Board, however, may prohibit the transportation of any sheep or goats through the state it feels represents a threat to the general health and welfare of the Idaho sheep industry.
