Which of the following is not a type of glass used in vehicles?

Double-glazed glass is not typically used in vehicles. Instead, double-glazed glass consists of two separate panes of glass that are sealed together with an air space in between. This design is primarily used in residential and commercial windows to improve thermal insulation and energy efficiency.

In contrast, tempered glass is known for its strength due to the heat treatment process it undergoes, making it ideal for side and rear windows in vehicles where safety and impact resistance are critical. Laminated glass consists of two or more layers of glass with an interlayer, providing additional protection and safety, often utilized in windshields to prevent shattering. Lexan, a type of polycarbonate, is often used in applications requiring lightweight and impact-resistant materials, but it is not standard glass.

Understanding the different types of glass and their applications in vehicles allows rescue technicians to assess and respond to emergency situations more effectively.
