The environment for this crash sequence was a 2-lane road with a bridge over a river. Impact occurred near the uphill exit of the bridge between a Ford Five Hundred and a Peterbilt tractor towing two trailers.
Light tire scuffs were visible prior to the impact position, indicating the Ford driver had attempted an aggressive avoidance maneuver. The impact caused counter clockwise rotation of the Ford off the road, and then over the embankment into the river.
