Calculating Speed from Yaw Marks
When a vehicle is in yaw it is rotating around a vertical axis through it's centre of mass. The long, curved yaw marks left by the tires on the pavement were characteristic of this motion. If they were striated and of constantly diminishing radius they were of great interest for collision reconstruction because the vehicle's speed could be determined from them.
