Which item is listed as requiring three or more measurements?

• A. Curved Skids
• B. Tire Marks
• C. Vehicles
• D. Debris Patches

Answer: (A)

Curvature in skid marks needs enough data points to define the path. A curved skid mark isn’t described by a single length or endpoints alone; you need three or more points along the arc to determine its shape. With three non-collinear points you can fit a circle, giving you the radius and center of the curve, which in turn lets you reconstruct the vehicle’s path more accurately. Two points would only define a straight line, which isn’t enough for a curve. More measurements along the curve reduce error and improve the path model. That’s why curved skids are listed as requiring three or more measurements.
