Establishes Alternative Responses to Reduce Instances of Violence and Escalation (ARRIVE) Together Program.

This bill establishes the ARRIVE Together Program to provide mental health crisis response alternatives to law enforcement. It requires law enforcement agencies (including state police, county police, and municipal departments) to partner with licensed mental health providers who can respond to calls involving mental health or substance use crises instead of police-only interventions. The program mandates confidentiality for all personal health information collected during responses and protects mental health providers from civil liability for good-faith actions taken during crisis interventions. The law applies directly to law enforcement agencies, mental health service providers, and individuals experiencing mental health or substance use crises during emergency calls.
