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 the occupants from wind, debris, and weather elements while providing clear visibility for the driver. Windshields are designed to be strong and shatter-resistant, often made from laminated safety glass. This type of glass consists of two layers with a plastic interlayer, which helps prevent shattering upon impact. Proper maintenance, including regular cleaning and prompt repairs of chips or cracks, is essential for safety and visibility.
