Next is the bumpy rides. When the car is riding on roads with many bumps, the crack may spread. The sudden path hole on the road also affects this. This is an extra vibration for the car. Due to that, the cracks may worsen. The third one is the poor installation.

When the mechanic installs the windshield incorrectly, the edges will not align perfectly. When riding on the road, there is a pressure of the wind and the force due to acceleration. Due to these reasons, cracks may spread. Choose an experienced mechanic when working with car faults.
