There are so many different ways that you can wind up with a damaged windshield. You might have been following a gravel truck too closely, or another vehicle could have kicked up road debris on the highway. Sometimes rapid changes in temperature can be a culprit. And perhaps you had a small chip or hairline fracture that you simply never got around to dealing with, and it suddenly took a turn for the worse. Whatever the case, your windshield is now heavily damaged, and your vehicle cannot be safely or legally operated until you get repairs.
