A loose rock hits your windshield and left in its place is a small crack. Most drivers will wonder: do I need to immediately replace the windshield, can it be repaired, and how long can I keep driving with the crack? Get some answers to your questions here.
According to Cars.com, the first thing you should do is measure the crack or chip in your windshield. Smaller cracks (chips smaller than a quarter and cracks less than a foot long) might be able to be repaired, saving you the expense of having to replace the entire windshield.
If the crack doesn’t impair your visibility while you’re driving, you might not need to repair the crack immediately.
However, if you are going to drive with a cracked windshield you need to take precautions to avoid making the damage worse. Cars.com recommends avoiding blasting your air conditioner or defroster, as temperature extremes can make the cracks worse. Instead, try to cool down or warm up your car gradually.
While you’re waiting to have your windshield repaired, you should also avoid washing your car, as the water can make the cracks worse. You should also try to avoid slamming the car doors.
