Buses are way more likely to be in accidents where they need to be able to break windows to get children out of the bus. It’s also expensive and heavy. If you want to stop rounds from an assault rifle, **[you’ll need rank B4 material](https://www.armormax.com/blog/how-thick-is-car-bulletproof-glass/)**: > Because the glass is so thick, the weight is increased dramatically. Regular windshield glass weighs around 25 pounds. A rank B4 windshield (generally around 20+mm thick) weighs between 150 – 250 pounds depending on the design… Also, the windows are only a small portion of the sides of the bus. You’d also need to up-armor the sheet-metal body to maybe 3/8" steel. Instead of a 25,000 pound school bus (meat filling not included), you’d end up with a 75,000 pound school bus and a gaping hole in your school budget.
