I am clueless on the windshield survey. Besides the common sense idea of looking to see which patients will have obvious head trauma and the potential for identifying the impact severity by looking at the glass damage.

Will you run through what you look for and subsequently what that tells you about the victims concerning windshield survey?

#1- make sure surrounding scene is safe from further incident. I would go to the front end damage vehicle first. Identify the leaking liquid to rule out an environmental danger (fire/explosion) before treatment begins on the actual passengers.
