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

S 4401 establishes the ARRIVE Together Program to provide mental health crisis response alternatives to traditional police involvement. The bill requires New Jersey law enforcement agencies (including state police, county departments, and municipal forces) to partner with contracted mental health providers who can respond to calls involving individuals experiencing mental health or substance use crises. Key provisions include mandating 24/7/7 mental health services, designating crisis response coordinators in police agencies and county prosecutors' offices, and protecting personal identifying information related to crisis responses as confidential. The program codifies a 2022 pilot initiative, aiming to reduce violence by connecting people in crisis with appropriate care instead of law enforcement escalation.
