What is the purpose of a post-install test drive check?

• A. Check engine oil level.
• B. Test drive to see if the car handles well with glass removed.
• C. To confirm proper visibility, no wind noise, correct seating of glass, and alert to any irregularities.
• D. Test drive is not necessary after windshield replacement.

Answer: (C)

After a windshield replacement, the post-install test drive check is all about safety and real-world performance of the new glass. The goal is to verify that the windshield is properly seated in the frame and sealed, that visibility through the glass is clean and unobstructed, and that there are no signs of problems such as wind noise, air leaks, or misalignment. Driving at normal speeds helps reveal issues like gaps along the edge, improper bonding, or interference with wipers and other components, and it allows you to notice any unusual vibrations or reflections that could affect safe driving. This step ensures the installation will hold up under typical driving conditions and alerts you to address any irregularities before the vehicle is returned to the customer.
