What type of vehicle glass is designed to break into small pieces rather than shattering into sharp fragments?

Tempered glass is specifically treated through a process of extreme heating and rapid cooling to increase its strength. This type of glass is designed to break into small, blunt pieces upon impact, minimizing the risk of sharp edges that could cause injury. This safety feature is particularly important in vehicle windows, where occupants may be at risk during accidents or collisions.

In contrast, laminated glass, which is often used in windshields, consists of layers with a special interlayer that holds the glass pieces together upon breaking, preventing shattering completely. Shatterproof glass is a more general term often used to describe glasses that resist breaking, but it does not specifically denote how the glass behaves upon shattering. Bulletproof glass, typically designed for security applications, consists of multiple layers of glass and plastics to stop bullets rather than breaking into small pieces. Therefore, the characteristics of tempered glass make it the correct choice when discussing the type of vehicle glass that breaks safely without creating sharp fragments.
