If you are not the first to arrive at the scene of an accident and your help is not needed, what should you do?

If you are the first person to arrive at the scene of a crash, you should immediately call 911. Otherwise, if you are not professionally trained to render aid, cautiously continue on. This will ensure that you do not interfere with the arrival of emergency services and will prevent you from being the victim of a secondary collision caused by other drivers distracted by the crash scene.
