_________ glass is often used in side and back windows.

• A. Laminated
• B. Tempered
• C. Annealed
• D. Float glass

Answer: (B)

The main concept is safety glass selection for different automotive windows. Tempered glass is heat-treated to increase strength, and when it breaks it shatters into many small, blunt pieces rather than large, sharp shards. This reduces the risk of serious injury to occupants in side and rear windows, which is why tempered glass is commonly used there. Laminated glass, by contrast, uses a plastic interlayer and remains mostly in one piece after impact, making it ideal for windshields where maintaining visibility is crucial. Annealed glass is the basic form that breaks into sharp, large shards, and float glass is simply the basic flat glass production and not specifically a safety implementation.
