Truck hanging off a bridge after serious traffic accident (India)

The accident happened shortly before, and the truck drivers (or what was left of them) had already been removed from the wreck.

It may look strange that the guardrail seems intact In fact a good section of the guardrail was destroyed (you can see the broken guardrail on this photo). The truck must have been going pretty fast when it flew off the bridge and hit the ground pretty fast and then rotated into a near vertical position after its front smashed the ground.
