No pre-impact skidding or braking. The driver was asleep, or distracted.
That had to be fatal or multiple fatal. Big time lawsuits...
Murderous runaway truck anyway. This is like the pistols that fire themselves (so says Alec Baldwin) and airplanes that just nose over and fly right down into the ground.
No operator error involved or considered at all.
No fatalities, lots of injuries though.
Look close, the driver made a slight swerve to the left a split second before the impact. Not asleep, just distracted.
