Pete is correct. Good Samaritan laws are fairly narrow in their protection, and aren't a guarantee that you won't be sued. It should be a real emergency: no breathing, no heartbeat, severe bleeding and shock. If you go beyond your knowledge and screw up, it won't protect you. Getting a person out of a car after an accident is not a good thing to do because you might compound injuries, but if the car is on fire, it's probably a good idea. If death or irreversible damage would occur before the EMT get there, your choices are limited & you would probably be covered. (Unless the victim is a NY City attorney, in which case maybe sneaking away before anyone gets your license plate would be the thing to do... <img src="/images/graemlins/smile.gif" alt="" />)
The Good Samaritin Laws are a sad gauge of our society. People used to help without thought of being sued. Then, in the 60's I believe, it was discovered that you might be able to sue someone for your early retirement, and people became reluctant to stop to help anyone due to that fear. People would watch other people die because they were scared of losing everything they had to help a stranger. Now, it is also a law in many states that you can be sued for FAILING to render aid.
I suppose you could call it a full circle of stupidity. <img src="/images/graemlins/frown.gif" alt="" />
