But fact is that even simple 2 tire and 4 tire vehicles can kick up rocks and it’s not possible to stay clear of all of them. For this, you simply have to use common sense and implement good driving habits such as tailgating and maintaining extra caution when you notice a vehicle or a truck pull up beside or drive in front of you.

Structural Weaknesses:

There are several windshields that are cracked approximately 3 inches away from the tip of the end mold. This is generally a result of a weak manufacturing process caused by the thermal effect during the manufacturing process. Given the fact that glass is made up of small particles and not liquid, these particles are unable to grip to the edge where no glass exists. Adding to this, the mechanical stress used to craft the glass and bind it with the interior plastic liner may cause imperfections and increase shock and the chances of cracks.


Unfortunately, car vandalism is unpredictable, but there are a few things you can to prevent it. For starters, always make it a point to park in well lit areas or even an indoor or locked garage. If you don’t have access to any of the above, park your car where it is clearly visible such as in areas that do not block your field of vision. You should have done this already, but in case you overlooked it for whatever reason, it is important to have an industry certified car alarm system installed in your vehicle. This will not only prevent thieves from prying into your vehicle, but also cut costs considerably on car insurance premiums.

Moisture can cause cracks in your windshield to expand at an alarming rate so it important to have damages to your windshield look at as soon as possible before they spiral out of control, making them more expensive to fix.
