Windshield cracks are irritating to all drivers, but they’re not always irritating enough to encourage them to do something about it. An older car makes more noise than it used to, and has probably collected its share of door dings. But a cracked windshield isn’t cosmetic damage. It’s dangerous and illegal to drive with a damaged windshield, and it increases your likelihood of getting a ticket or getting into an accident. A chipped windshield or a cracked windshield can also get more damaged if you wait too long to get it repaired.
