Which agency regulates ambulance services in the United States?

The National Highway Traffic Safety Administration (NHTSA) is the correct agency responsible for regulating ambulance services in the United States. NHTSA plays a crucial role in ensuring the safety of vehicle operations, including emergency medical services. It establishes guidelines and standards for ambulance design, equipment, and operational practices to promote safety and efficiency in emergency response. This agency also supports training and compliance measures that enhance the performance and reliability of ambulance services.

While the other agencies mentioned may have roles related to health and emergency services, such as overseeing public health policies or disaster response, they do not specifically regulate ambulance services. The Department of Health and Human Services focuses on broader health-related issues, FEMA deals with disaster management and recovery rather than direct regulation of ambulance services, and the American Medical Association is an organization that advocates for physicians and medical practices, rather than an official regulatory body for ambulance operations.
