What Causes Windshield Cracks?

As unfortunate as they are, windshield cracks are bound to happen if you don’t take proper care of your vehicle. However, even if you do take special care to avoid damaging your car’s windshield, cracks and chips can still occur. What can cause a windshield to crack in these kinds of situations, where an obvious answer doesn’t seem to exist? Follow along as Rock Chip Squad examines some of the most common examples of what causes windshield cracks.

  • Glass Imperfections – One of the most unfortunate contributors to cracked windshields is improper construction. Some windshields simply come out of the production line with structural weaknesses already in them, which means they could shatter at any time during regular use. The same could also be true if the windshield was installed improperly. A misaligned windshield or window can be more susceptible to cracks and breaks.
  • Pressure Changes – Pressure changes and fluctuations can cause your windshield to experience extra stress, making it much more susceptible to cracks and breaks. This means that the many different examples of what causes windshield cracks could be even more destructive after pressure changes.
  • Gravel Roads – By far one of the most common causes of a shattered windshield is kicked-up gravel. Small pebbles and road debris get kicked up toward your windshield at high speeds, and if they hit at the wrong point or angle, your windshield could very quickly end up looking like a spiderweb of glass.
  • Construction Vehicles – Following a construction vehicle puts your windshield at extra risk of shattering due to small stones and debris. This usually occurs when you drive too close to these types of vehicles. By leaving extra space between your car and construction vehicles, you stay safer and keep your spending on windshield replacements down.
  • Hail and Other Debris – Hail is one of the most common examples of what causes windshield cracks, especially in vehicles that are kept outside. Everyone has heard stories about abnormally large hail damaging vehicles, and they’re no joke. It’s generally a good idea to keep your vehicle inside a garage or storage unit or underneath some sort of outdoor shelter, which can prevent damage to your car.
