Every now and then a customer will ask me, When I am driving around with a crack across my windshield will it collapse in on me? The answer is no.. The windshield is made up off two layers of glass with a piece of safety laminate between the them, This construction helps hold the windshield together… Although the windshield is structural part of the vehicle, it does come into play in the case of a rollover or when the airbags are deployed.
