Cal Bus & Prof Code 3503.5
Good Samaritan Law: Physician Assistant
A licensed physician assistant who, in good faith, provides emergency care at the scene of an emergency which occurs outside the physician assistant's employment will not be held legally responsible for acting or failing to act. They can be held legally responsible if acting with extreme carelessness. Generally, Good Samaritan laws only offer protection for those individuals who provide care during spontaneous emergencies unrelated to volunteer deployment.
