Your vehicle’s windshield does more than just keep the wind and elements out of your face. It is an integral part of the safety restraint system, which is why you should always have the glass repaired or replaced at the first sign of any damage. Your windshield is classified as a "safety device" because it provides structural strength to the car’s body, helps keep passengers inside the vehicle in the event of an accident, and supports the inflation and performance of passenger-side airbags.
