The main purpose of this legislation is to create a grant program aimed at improving the mental health and overall well-being of first responders, such as emergency medical services (EMS) personnel and firefighters. The program is designed to address the high levels of stress, mental health challenges, and the risk of suicide that these individuals often face due to the nature of their work. Key provisions of the legislation include the establishment of the EMS and First Responder Wellness Grant Program, which will be managed by the National Highway Traffic Safety Administration.
