Fun Facts About Windshields (Part 3): How Fast Does Auto Glass Break?

I would bet money that we’ve all experienced a chipped or cracked windshield (or two) in our time on the roads.Oftentimes, you don’t even realize how you got the windshield damage. You just wake up one day…and there it is. A nice-sized chip smack dab in the middle of your windshield. But sometimes, you actually get to see your windshield crack with your very own eyes. We get it. No one wants a cracked windshield. But if you get to witness it, it’s actually pretty amazing.

Windshields are pretty remarkable. We’ve talked a bit about the types of glass used in windshields, the history of windshields in the past, and most recently, Auto Glass 2020 started a new blog series about all the fun facts on windshields. If you’ve missed these, you can read about luxury windshields here and the invention of shatterproof glass here. Well, here’s another fun fact about windshields, specifically cracked windshields:


When auto glass breaks, its’ cracks spread at 3,000 mph!

Wow. Just wow.

That type of speed is almost unimaginable.

Cracked windshields often start as a small chip. But with time, these chips can evolve into a longer, deeper crack that can significantly affect the overall function and safety of your vehicle. And sometimes, cracked windshields don’t even start as a small chip. If that piece of gravel or debris hits your windshield in just the right spot at just the right speed, you might witness your windshield cracking at the speed of light. Well, that may be a slight exaggeration because, ahem, the actual speed of light is 186,000 miles per second. But 3,000 mph is still really fast!

So, why do we care how fast windshields and auto glass can break? Very good question!

Well, it’s important to realize how quickly your windshield damage can worsen. And the more windshield damage (aka chipped or cracked windshields) you have, the more risk you are taking when you’re out on the roads. As we always stress, the windshield is integral to overall vehicle safety, so it’s just not worth it to drive around with windshield damage if it puts you, your loved ones, and others on the road at risk.
