Voldemort - Transport has been one of the most criticised parts of MES. See this :

There are threads on QL itself on the same, and even local newspapers ran stories about that.

The level of carelessness varies from one school to another, on various topics. I heard that BPS is doing pretty good on the transport side, mainly because the principal himself is present while the students are alighting or boarding the buses in a fairly congested area. There are also common sense rules implemented there, like keeping the doors open on the buses for couple of hours.

Condolences to the family of the little one, who paid the price for the folly of others.
