Thoughts and condolences to the friends and family of the 4 people who died.
I am guessing , but I think the 4 were a family. 2 adults, and 2 teenage girls, sounds like a family.
Also the whole illegal turn is irrelevant, if they had turn right result would have been similar, they would have been hit more in the rear or at a angle
so not quite as bad.
The only thing is did bus have lights on? was it dark or near dawn? how fast was the bus going?
Why did the driver of the van not see a big white bus?? or think he would not be hit by it.
Seems to me the car pulled out and was immediately hit in the side, and was carried way down the road or knocked way down.
In the first link in op post, look at the pictures, and videos of the van, and then see if you think 55,mph would do that
It might, since vans are weak vehicles, but this looks like a high speed impact.
I think the main fault would be with the driver of the van, pulling out and not seeing a bus is bad, and then trying to go left which at that point
was actually straight ahead, was all on him
But if the bus was doing 90 and not paying attention, then some fault would be with the driver of bus.
No brakes hit means the bus driver did not see that the van was pulling out, and again they must have been either going really fast
or the van just pulled out right into them.
