Which statement about automotive safety glass is correct?

• A. All glass is tempered
• B. Windshields are tempered
• C. Automotive safety glass is tempered or laminated; windshields are laminated; side/rear glass may be tempered.
• D. There is no safety glass

Answer: (C)

Automotive safety glass comes in two main forms: tempered glass and laminated glass. Tempered glass is heat-treated to be very strong and, when it breaks, it shatters into small, dull pieces to reduce cut injuries. Laminated glass uses two glass layers with a plastic interlayer that holds the shards together, providing a continuous barrier and helping keep the glass in place during a crash. Windshields are laminated because they must maintain a barrier and support the structure, while side and rear windows are usually tempered to minimize injury from shards, though some designs use laminated glass for extra protection. So the statement that automotive safety glass is tempered or laminated, windshields are laminated, and side/rear glass may be tempered correctly reflects standard practice.
