Your windshield plays an important role in keeping you and your family safe. In the event of an accident the windshield needs to remain in place for the airbag to use as a backboard, keeping the passengers in the vehicle safe. It also assists in maintaining the vehicle's structural integrity, helping prevent the roof from collapsing during a rollover. A faulty installation compromises your safety.
