There has been a collision. A motorcyclist is lying injured and unconscious. Unless it’s essential, why should you usually NOT attempt to remove their helmet?

Explanation: When someone is injured, any movement which is not absolutely necessary should be avoided since it could make injuries worse. Unless it is essential, it's generally safer to leave a motorcyclist's helmet in place.
