For curved skids, how should the distance be measured?

• A. Measure the skid with the curvature, lay the tape down or roll the distance with a roll-a-tape
• B. Use straight-line distance
• C. Only measure the wheelbase
• D. Estimate using GPS

Answer: (A)

When a path is curved, you measure the actual arc length rather than the straight-line distance. Use a flexible tape or a roll-a-tape that can conform to the curve and follow the skid’s path from start to finish. This captures the true distance the skid travels along the curve. A straight-line measure would miss the curved portion and be inaccurate, and measuring only the wheelbase ignores most of the path. GPS estimates can be imprecise and may not trace the exact curved route. So, measure along the curvature to get the true distance.
