Regardless of the reason why your car windshield has been damaged it needs to be repaired as soon as possible. You may believe that a simple tiny rock chip is harmless, if the chip becomes larger or cracks, guess what, it is no longer harmless and you will have no choice but to have a rock chip repair done. That is if you're lucky and do not need a windshield replacement because you waited too long.
The first and most important reason you should not put off getting a windshield repair on your car is for your safety and the safety of every passenger in your car.
If your driving down the highway at 55 mph and your windshield chip becomes a large crack, there is a good chance it will startle you and you could lose control of your car and be involved in a serious automobile accident. Is it really worth it to put off a rock chip repair and put your life and lives of everyone in your car and any other cars involved in an accident? Not when an auto glass repair is quick and inexpensive.
Rock chips are among the most common and minimal types of windshield damage, but that doesn't mean they're not serious. Some chips actually require a full windshield replacement, even if they're tiny or out of the way.
