In a warm summer afternoon a truck smashed through a highway's median guard rail and disastrously collided with the oncoming vehicles on the opposite roadway.

As result, seven people died charred:
Both trucks' drivers, two people in the 1st car (a mercedes) and three people in the 2nd car, a BMW 530 tailgating the 1st car.
The occupants of the yellow van were not injured and a few seconds later they got out of their van.

The BMW's tail was still looking good for spare parts!

Further investigations established that the cause of this fatal accident may have been a mechanical failure on the truck's front left suspension.
