When cutting laminate windshields, where should the initial cut be made to minimize breakage?

• A. down each side.
• B. across the bottom of the windshield.
• C. a starter hole in the bottom right corner.
• D. across the top of the windshield.

Answer: (A)

When working with laminated windshields, the goal is to control how the crack develops so you don’t trigger an uncontrolled, dangerous break. Laminated glass has two glass layers bonded by a plastic interlayer, so cracks tend to follow a path that the interlayer guides. Initiating the cut along the side edges gives you a long, accessible, straight edge to guide the blade and lets you slowly propagate the crack in a controlled manner. This approach minimizes abrupt breakage and reduces the risk of jagged shards or a large, sudden failure that could hinder access or injure nearby people. Starting cuts at the top, bottom, or from a corner can create stress concentrations and unpredictable crack paths, making the situation harder to manage.
