Will driving over glass pop a tire?

There was an accident near my house recently with a lot of broken glass in the intersection. I have to drive through that intersection, but I’m worried about driving over the glass because I just put new tires on my car. My roommate thinks I’m being paranoid, but I don’t know. Can broken glass cause a flat tire?

I totally understand your anxiety. Everyone knows that tires aren’t cheap. And glass is sharp, so a meeting of the two seems like it would spell disaster!
While your roommate could’ve chosen their words better, they are right in that you have nothing to worry about. There are two reasons why driving over glass won’t pop your tires—one has to do with the glass, and the other has to do with your tires.
Glass from automobiles (the most common kind of glass you’ll find on roads) is safety glass. It’s designed to break into small, nugget-like pieces without many sharp ends.
In addition, it’s more likely to be crushed under your tire than it is to puncture it because your tires are steel-belted (unless they were manufactured before 1970). This obviously doesn’t make tires immune to damage, but it does help them remain resistant to punctures.
So if your tires are still in good condition, you don’t have much to worry about. While it is best to avoid debris like
when you can, rest easy knowing that if you can’t avoid driving over glass, it shouldn’t damage your tires.
