Yes. Getting your windshield fixed is necessary for your safety, as well as the safety of those in the car with you. Your windshield protects you from the elements, and gives you better visibility. A little less known fact is that windshields also make up 40-50% of your vehicles roll over strength. Windshields are also used in air bag safety. When your air bag goes off it pushes against the windshield and dashboard to make it inflate your direction rather than inflating upwards. If a windshield is already cracked or improperly installed it may not hold in the case of a crash and the airbag loses much of its support.
If you’re not sure if your windshield is repairable, get it looked at by an auto glass specialist. It’s worth not having to replace your windshield as it is significantly cheaper to repair. Most repair shops can repair chips up to the size of a quarter. Most can also repair cracks up to about 4 inches long while, some shops use special techniques that allow them to repair cracks significantly longer. The key to saving your windshield is responsiveness in getting it repaired soon after the damage is done. The longer you wait the more the damage can spread, and if left unrepaired long enough, can result in the need of a windshield replacement. However know that most shops will recommend you replace the windshield if the damage obstructs the vision of the driver.
There are 4 different types of general windshield chips.
