在美国，好撒玛利亚人法的目的是给予医生、护士和急救人员责任豁免权，使他们在医院以外为伤患急救时没有后顾之忧，美国法庭的判决也努力为急救人员的救护行为提供保护。
如果一个医生驾车时发现路边出现交通事故，他没有停下车来提供急救的法律义务。他有可能因为担心承担法律责任而不愿意这么做。因此，好撒玛利亚人法就为自愿提供急救的医生和普通人提供了保护。如果医生没有急救的法律义务但还是提供了救护，在这种情况下，除非他是出于恶意或构成严重过失，否则被救护的人就不能因医疗事故告倒他。这样，医护或非医护人员就能坚持自己帮助他人的信仰，而又受到法律保护不被伤害。
參考答案:In USA, Good Samaritan Laws are enacted to prevent a rescuer(doctor,nurse,and those who come to the first aid to others) who has voluntarily helped a victim in distress for no other reason than kindness, from being successfully sued for "wrongdoing".Its purpose is to keep people from being so reluctant to help a stranger in need for fear of legal repercussions if they made some mistakes in treatment.Therefore, this doctrine is primarily developed for first aid encounters.Any person who, in good faith, renders emergency medical care or assistance to an injured person at the scene of an accident emergency without the expectation of receiving or intending to receive compensation from such unjured person for such service, shall not be liable in civil damages for any act, not constituting gross negligence, in the course of such care or assistance.Doctors or nurses who have beliefs in saving people's lives will no longer fear of being accused for possible danger when coming to a first aid in emergency situation.
