Nev. Rev. Stat. § 41.0332
County school districts and local law enforcement agencies are not liable for the negligent acts or omissions of a person who volunteers to serve as a crossing guard, unless:
2. The conduct of the volunteer affirmatively caused the harm.
The provisions of this section are not intended to abrogate the principle of common law that the duty of governmental entities to provide services is a duty owed to the public, not to individual persons.
