Police were called to the scene of an accident where a car headed east collided with the
side of a second car in a 'T-Bone- style crash as show below. Both drivers reported very
different stories.
The driver of the first car claims that he was driving at the speed limit when the second
car flew through the intersection. He collided with the car before he was able to hit the
brakes.
The driver of the second car claims that she had accidentally stalled in the middle of the
intersection and was not moving when the first car came flying towards her. She claims
the first car was traveling way above the speed limit.
The skid marks (the lines tires make) are shown from the second car traveling sideways.
It was confirmed that both cars were brought to stop by the second car sliding along the
road.
When the vehicle collision investigator arrived at the scene, he could tell immediately
who was lying.
