Side windows are the vertical glass panels located on the sides of a vehicle, typically found in cars, trucks, and buses. They allow passengers to see outside while providing ventilation and light inside the cabin. Side windows can be manually or electronically operated, enabling them to be opened or closed as needed. In addition to their functional purposes, side windows also contribute to the overall design and aesthetics of a vehicle. They are often made of tempered glass for safety and durability. Many modern vehicles feature tinted side windows to reduce glare and heat from the sun, enhancing passenger comfort and privacy.
