Ik this is a bit late but I was on the bus when it happened. The police haven’t released the reason not even to my school but If your curious I’m gonna say what it was like in there. So basically it was a normal day on our bus it was very quiet and sunny and we were going along the back roads (which are very thin) and it made this juder noise as if the wheels were jammed then it stopped for a second and went in. I hope that explains well
