Why is proper windshield installation critical for vehicle safety in a rollover accident?

Proper windshield installation is critical for vehicle safety in a rollover accident because the windshield provides significant structural support to the roof. The windshield is bonded to the vehicle's frame, and it acts as a key component in preventing the roof from collapsing in a rollover. A properly installed windshield helps to maintain the passenger compartment's structural integrity, reducing the risk of injury to the occupants. If the windshield is not properly installed, it can detach from the frame during a rollover, weakening the roof structure and increasing the likelihood of roof collapse. This can result in serious head and neck injuries for the vehicle's occupants. The adhesive used to bond the windshield to the frame must be applied correctly and allowed to cure properly to ensure a strong and secure bond. Improper installation techniques or the use of incorrect adhesives can compromise the windshield's ability to provide structural support in a rollover accident. Also, the windshield is part of the airbag deployment system, providing a backstop for the passenger airbag.
