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 withstand impacts and are often made with laminated safety glass to prevent shattering. In addition to safety, windshields play a role in the vehicle's aerodynamics, helping to reduce drag and improve fuel efficiency. They are also integrated with features like wipers for clearing rain and defrosters for maintaining visibility in cold weather. Proper maintenance and timely replacement are essential for ensuring safety on the road.
