What is the main reason why vehicle windows must be made of safety glass?

Question

DentroTest · Accepted Answer

Vehicle windows are a fundamental element of passive safety. Regulations require them to be 'safety glass' (usually laminated for windshields and tempered for side windows) specifically to avoid causing serious injuries if they break. Unlike conventional glass, which shatters into large, sharp shards, safety glass crumbles into small, rounded granular chunks (tempered) or stays attached to a plastic layer (laminated), minimizing the risk of deep cuts to occupants in the event of an accident. While wind resistance and clarity are important, they are not the reason for the 'safety' designation.
