Which statement about tempered glass is true?

• A. It is softer than laminated glass
• B. It is used in only certain vehicle parts
• C. It is lighter than laminated glass
• D. It is harder than laminated glass

Answer: (C)

Tempered glass is a single pane that has been heat-treated to greatly increase its strength, while laminated glass is made from two panes bonded together with a plastic interlayer. That interlayer plus the extra pane adds weight, so when you compare panes of similar thickness, tempered glass is lighter than laminated glass. In vehicles, this contrast matters: windshields are usually laminated for containment if shattered, whereas side and rear windows are often tempered for weight and break behavior. The other statements mix up how tempered glass behaves or is used, so they don’t fit as well.
