Rear windows are the glass panels located at the back of vehicles, providing visibility for drivers and passengers. They are designed to enhance safety by allowing the driver to see behind the vehicle while reversing or changing lanes. Rear windows can be fixed or operable, depending on the vehicle design. In addition to their functional role, rear windows often come with features like defrosters to clear fog or ice. They can also be tinted for privacy and to reduce glare from sunlight. Many vehicles use automotive glass that is tempered or laminated for added strength and safety.
