that assists the driver, like an overseer in the bus for the safety of kids to & from school. A routine checkp-up everytime the school bus upload & unload the kids. I'm sure it's not a hard thing to do.
Now that there's another accident happened I hope the school administration, irregardless of which school it would be, should look up to also the welfare of their pupils not only inside the school campus but like wise including school bus/transport.
This is really important as there was again one precious life lost due to negligence.
