A windshield is a transparent panel made of glass or plastic that is installed at the front of a vehicle, such as a car or truck. Its primary purpose is to protect passengers from wind, debris, and weather elements while providing clear visibility for the driver. Windshields are designed to withstand impacts and are often made with laminated glass for added safety. In addition to protection, windshields play a crucial role in the structural integrity of a vehicle. They help support the roof and prevent it from collapsing during accidents. Windshields also work with other components, such as wipers and defrosters, to enhance visibility in various driving conditions.
