In California the "Good Samaritan" laws were recently crippled by our state Supreme Court. A person who pulled someone from a vehicle they thought was going to catch fire was sued by the person they rescued. The victim ended up paralyzed, and doctors weren't sure if it was from the original crash or from the removal. CA Supreme court allowed the suit, 4-3. They ruled the Good Samaritan law only protects you when you are giving "emergency medical care", and not for any other acts.
