In rural areas, motorists often have to deal with farm equipment traveling slowly on roads. In this case, a farmer driving a tractor starts across a state highway near a hilltop. He looks both ways and sees no traffic. Halfway across, a car cresting the hill strikes the tractor. The tractor is overturned and the car goes into a spin, leaving the road.

Because there are no fatalities and only local police were involved, very little information was gathered. The photos were poor and didn't show all the marks on the road. We used photogrammetry to place what marks were photographed on a scale drawing and then worked the dynamics of the vehicles to match the evidence.

We determined that the driver was speeding and because of the hill, could not see the tractor until too late.
