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

This bill establishes the ARRIVE Together Program to provide mental health and substance use crisis response as an alternative to standard law enforcement interactions. It requires law enforcement agencies (including state police, county departments, and municipal forces) to partner with mental health providers available 24/7 for crisis calls, with designated coordinators in each agency and county prosecutor's office. The program ensures confidentiality for all personal information shared during responses and shields mental health providers from civil liability when acting in good faith. It codifies a temporary pilot program into permanent law, creating structured coordination between law enforcement and mental health services.
