Truck accident reconstruction

This is a brief version of my reconstruction in Swedish.

Time counter numbers below refer to this video (opens in new window)
recorded by Ms. Gunn Iren Johnsrud and broadcast via TV2 in Norway.

1) Downhill slope forced driver to brake
– brake-light here at counter time 00:00:28 seconds

2) Snow-chains only on tractor rear right wheel. See TV2 photos on

3) Road banking applied gravity side forces irresistible to (braked) front wheels.
Tracks in snow deviate to right (00:00:35) – though driver steers left:
see front wheel at 00:00:34, 35 and 38 seconds

4) Superior braking and side forces on tractor rear right wheel add to clockwise moment (turning tractor to right) irrespective of driver’s full left steering.
