The Idaho Fish and Game's motorized hunting rule applies only to big game animals, including moose, bighorn sheep and mountain goats, in designated units from August 30 through December 31.
Between these dates and in the designated units, specific to all big game hunting, hunters may use motorized vehicles only on established roadways that are open to motorized traffic and capable of being traveled by full-sized automobiles.
Motorized hunting use restrictions apply to units in orange on the map. The rule does not apply to upland game animals or birds in hunts within designated units. The rule applies to motorized vehicle uses by hunters off an established roadway, except:
Holders of a valid disabled person’s motor vehicle hunting permit may use a motorized vehicle as allowed by the land owner or manager.
Hunters may use a motorized vehicle to retrieve downed game if such travel is allowed by the land owner or manager.
Hunters may use a motorized vehicle to pack camping equipment in or out if such travel is allowed by the land owner or manager, but hunters may not hunt while packing camping equipment.
Private landowners on their private land, their authorized agents and persons with written landowner permission are exempt from the motorized hunting rule restrictions.
