So think the driver set the bus on fire deliberately ? That would be extremely unlikely .Somehow a fuel line broke then sparks from the impact set the fire off .In truth i do not know ,,,,,and i am just speculating .I have seen in the past lots of crashes resulting in fires ...There is also the possibility that the driver fell asleep at the wheel .
A tire blew out making the bus hit a concrete barrier .Thats what i heard ,so not the drivers fault if true .You said that he was uneducated .If he had a University degree it would not have helped any .
