The main purpose of this legislation, known as the "To Inform Families First Act of 2025," is to encourage states to voluntarily include emergency contact information in their driver's license and identification systems. The goal is to enhance public safety by ensuring that in case of an emergency, first responders can quickly access important contact information for individuals involved. Key provisions of the law include the establishment of a grant program by the Secretary of Transportation to assist states in developing and implementing these emergency contact information systems.
