How to correctly use the car safety hammer
1.First, take out the window breaker from the vehicle and directly hammer the four arbitrary corners of the tempered glass, instead of hitting the middle part, as this is the strongest part of the entire glass
2. When cracks appear, it indicates that the interior of the glass has been greatly damaged. At this time, only a few more blows are needed to break the glass
3.If the glass has a film attached, it needs to be vigorously kicked away with your foot, as the film has an anti burst function and will not fall off without external force.
4.When the glass falls off to a certain extent, passengers can jump out of the window in time and move to a relatively safe place
