N.C. Gen. Stat. 20-166(d)
Good Samaritan Law
An individual, who provides emergency assistance to an injured person at the scene of a motor vehicle crash, will not be held legally responsible for acting or for failing to act. They can be held legally responsible if acting with extreme carelessness or intent to cause harm. Generally, Good Samaritan laws only offer protection for those individuals who provide care during spontaneous emergencies unrelated to volunteer deployment.
