The most common cause of cracks in windshields is the impact of a rock or other debris kicked up by the tires of other vehicles. However, there are other potential causes, such as extreme temperature changes, manufacturing defects, and other types of impacts. Sunlight has a similar effect to temperature changes, heating up the metal near the edges faster than the center of the windshield and causing cracks. Pressure changes due to sudden gusts of wind or even placing something heavy on the windshield can also be enough to create a crack. Windshields are made of glass and plastic components, so they can only withstand limited pressure.
Applying too much pressure to any area of the windshield's surface can cause cracks to form in or around that particular area. If the crack is right in front of you while you're driving, it's usually best to replace the windshield, as repairs may cause the area to become blurry. While a surprise crack in the windshield can be frustrating, you should know that windshield repairs aren't difficult and are often covered by car insurance. Depending on the location of the crack, you may only need to repair the windshield, rather than having to replace it. If your windshield is cracked but you don't have time to take it to an auto glass repair shop, mobile windshield repair services offer a suitable, safe, and cost-effective solution. The chances that the windshield crack will be effectively repaired are usually related to how long it has been since the accident.
The windshield is more likely to have cracked due to one of the lesser-known causes of windshield cracks, chips, and other breaks.
