?WHY DO WINDSHIELDS CRACK



While cracks in your car’s windshield can be a hassle as they can make it more difficult to see properly when driving, it’s inevitable that you will likely deal with a cracked or chipped windshield at some point in your life. While windshields are designed to withstand a great deal of wear and tear, they are still made of glass and can be prone to cracking. To help you better understand why windshields crack, and what you can do to protect your car’s windshield, here’s a look at three of the most common causes.





Extreme Temperature Changes

One of the most common reasons for windshield cracks is extreme temperature fluctuations. The problem is that glass expands when it is warm and contracts when it is cold. While automotive glass is designed to withstand the thermal strain that regular changes in weather can cause, extreme shifts in temperature can result in cracks. If the weather is close to freezing one day, and the next day it reaches 70 degrees or above, this extreme temperature change can cause your windshield to crack. Parking your car in a garage can help reduce the impact extreme temperature changes can have on your vehicle and avoid using hot water to defrost your windshield in the morning, as this can also cause the glass to crack.


Sunlight

Direct exposure to sunlight on hot days can be another reason why your windshield may seem to unexpectedly crack. When the sun’s rays hit your car, this can cause the metal and other materials surrounding your glass windshield to heat, which causes the glass at the edges of your windshield to expand quicker than the glass in the middle, resulting in cracking. You can help to avoid this problem by parking your car in the shade or in a covered space on hot sunny days.


Driving Behind Construction Vehicles

It’s always startling to have something hit your windshield, suddenly causing it to crack. One of the most common causes of windshield cracks on the highway is driving behind construction vehicles. Large trucks and construction vehicles are more likely to kick up gravel and debris on the road, and if you are driving behind them, this debris can crack & break your windshield. Avoid driving behind these trucks when possible, but if you are stuck behind one of these trucks, give yourself plenty of space between your vehicle and theirs to minimize risk. Drive slowly, and increase your following distance behind other vehicles when driving on dirt or gravel roads.
