Template:Unreferenced Car glass includes windscreens, side and rear windows, and glass panel roofs on a vehicle. Side windows can be either fixed or be raised and lowered by depressing a button (power window) or switch or using a hand-turned crank. The power moonroof, a transparent, retractable sunroof, may be considered as an extension of the power window concept. Some vehicles include sun blinds for rear and rear side windows. The window shield of a car is appropriate for safety and protection of debri in the road. It also comforts the driver as well.
