A small number of states have “open range” districts where land-owners are legally permitted to allow their animals to roam at large, subject to restrictions set by state or local law.
Generally, motorists in open range districts have little or no recourse if they are injured in a collision with loose livestock, but exceptions can exist. In one case from Idaho, the landowner was immune from liability in a wrongful death action when a motorcyclist collided with a loose calf along the roadway in an “open range” district and was killed. The motorcyclist’s estate sued the landowners and the animal’s owners. They argued, in their defense, that they were immune from liability because the incident occurred in an area that was designated as “open range” under Idaho law [Idaho Code § 25-2118]. The trial court agreed and dismissed the case.
The case proceeded to an appeal where the motorcyclist’s estate challenged the “open range” classification. The Idaho Supreme Court upheld dismissal of the case and found that the “the ‘fence out’ rule prevails in Idaho, and that where a herd district has not been established, cattle are customarily permitted to roam." Nationwide, most states do not have “open range” districts. Each state differs. In any vehicle/livestock collision matter, make sure to review the applicable law carefully.
