What is the most important kind of scuff mark?

• A. Skid marks
• B. Yaw
• C. Scratches
• D. Groove marks

Answer: (B)

When analyzing tire marks, the crucial detail is what each mark reveals about how the vehicle moved. Skid marks mainly show braking and can help estimate speed at a point, but they don’t capture how the car was rotating or steering through a turn. Yaw marks indicate the tire sliding as the car rotates about its vertical axis, which happens when the driver is steering or the vehicle is losing control. This rotation and path information is exactly what helps reconstruct the car’s trajectory, orientation, and turning behavior during the incident. Scratches or groove marks don’t provide that same level of motion detail, so they’re less informative for understanding the overall movement. So, yaw marks are the most informative for understanding how the vehicle was moving and turning.
