How to Use a Car Window Breaker?

[RobertAnn]

First, take out the safety hammer from the car, then directly strike the four corners of the tempered glass. Avoid hitting the center initially. When slight cracking appears, it indicates that the stress distribution inside the glass has been significantly disrupted, causing numerous cracks to form instantly. If the glass has a film, you need to exert force to kick it open, as the film has anti-shatter properties and won't detach without sufficient external force. Once the glass has loosened sufficiently, passengers can promptly and orderly exit through the window and move to a relatively safe location.
