The Star of Life is a blue, six-pointed star, outlined with a white border which features the Rod of Asclepius in the center, originally designed and governed by the U.S. National Highway Traffic Safety Administration (NHTSA) (under the United States Department of Transportation, DOT). Traditionally in the United States the logo was used as a stamp of authentication or certification for ambulances, paramedics or other EMS personnel. Internationally, it represents emergency medical services (EMS) units and personnel. A similar orange star is used for search and rescue personnel and yet another version is used for Wilderness emergency medical technician.
