Can you drill a hole in a windshield to stock a crack from spreading?
A long crack in my car’s windshield keeps spreading. I heard you can drill a hole in your windshield to prevent a crack from spreading. Is that actually true?

Yes—you can drill a hole in a windshield to stop a crack from spreading. However, it’s a very delicate procedure, and most people who attempt it do not do it correctly.
The process, which is called “anchoring a crack” requires a very fine drill to be used to drill at least 0.42 inches into the glass—but no more than 0.6 inches, as that would damage the laminate.
The idea is to position your hole about 1/32 of an inch in front of the path of your spreading crack, then let the crack spread into it. There, its growth will be arrested by the hole—assuming you have drilled properly.
In the future, you can avoid having to deal with stressful and precarious DIY solutions like this by ensuring that any necessary repairs are covered by your car insurance and, you can make sure that
the cost of your car insurance
