Livestock on Highways
Livestock owners are also exempted from
damages related to animals on highways
passing through open range. A.B. 436 (Chapter
301, Statutes of Nevada 1965), defined open
range and further provided that an owner of any
domestic animal running on open range has no
duty to keep the animal off any highway
traversing or located on open range, nor may
the owner be held liable for any damages
caused by any collision between a motor
vehicle and an animal on such highway. In fact,
motorists that hit and maim or kill livestock on
highways on open range are liable to the
livestock owner for damages to the animal.

The cow wasn’t on the highway, it was on the interstate. A completely different case and free range does not apply to interstates.
Thanks for the exact wording.
