The laminated safety glass is a treated glass that holds together instead of shattering when impacted even in situations of a crash. That is, it will only crack but will not shatter which makes it safer.

These kinds of windshields help to contribute to how strong a vehicle is. Also, because they crack and do not shatter, they can easily be repaired.
However, if the impact of the crash is great, it can become broken or cracked beyond repair. In these kind of situations, it needs to be replaced. The tempered glass at the back of the vehicle does not have the same characteristics. It can shatter into pieces when there is an impact.
