This first figure shows a computer-generated illustration of a post being struck on its upper left-hand side by the impact vehicle. The top half of the post is colored a light green, while the lower quarter is colored a dark blue. The post has split due to impact where the green section meets the blue section, and the top half of the post leans considerably to the right. The split has caused a gap to form and a fracture to run lengthwise up a small portion of the post, while the back half of the post remains in tact and appears to be bending beneath the stress of the impact.

The top half of the post has become completely severed from the lower half, each section of the split appearing jagged and rough.
