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:
1. The volunteer made a specific promise or representation to a natural person who relied upon the promise or representation to the person’s detriment; or
2. The conduct of the volunteer affirmatively caused the harm.
Ê 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.
