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)
The Star of Life is a cross symbol used by the emergency medical services. It is commonly seen on ambulances and paramedic badges.
It is usually blue and features the familiar medical symbol in the centre; the Rod of Asclepius. (This was originally a pagan symbol but later adopted by Judaism, Christianity and Islam. See Serpent Cross.)
The six arms of the Star of Life represent some of the aspects of emergency medical care: detection of the problem, reporting to the appropriate professionals, response with first aid, on scene care until transportation is available to take the victim to a place with better facilities, care in transit continuing the first aid treatment,transfer to definitive care handing over responsibility
