It would be tempered glass - which breaks into crumbles, as compared to laminated/safety glass, which also breaks into crumbles, but generally stays in place due to a sandwiched plastic sheet bonded to the glass.
A window punch (or the breaker devices
@Just-Thinking-51 mentioned) will work fine on tempered glass- the whole sheet will turn to crumbles and pretty much fall away.
Window punches on laminated/safety glass may or may not work - usually, the just "peck" or crack a small area around the point of impact, though sometimes the entire sheet will crumble, while still staying attached to the plastic laminate, and have to be pulled away with some force, still in flexible sheet.
Your car, for instance, has a safety/laminated glass windshield. The side windows are likely tempered glass (though more and more cars now have laminated glass in the side windows for safety and noise insulation).
I don't think you'd find plate glass (breaks into shards) in a transportation application pretty much anywhere.
