Which of the following is NOT among the three measurements needed to be taken at all crashes?

• A. Point/area of impact
• B. Street width
• C. Tire/skid marks
• D. Vehicle color

Answer: (D)

When reconstructing a crash, the focus is on measurements that reveal how the vehicles moved and interacted on the scene. The point or area of impact pinpoints where the collision occurred, giving a critical reference for mapping trajectories. The width of the street provides a scale so distances and positions can be measured accurately in relation to the roadway, which helps determine lanes involved and vehicle paths. Tire or skid marks capture the vehicle’s movement before stopping, offering clues about speed, braking, and direction. Vehicle color, while useful as a descriptive detail for identifying vehicles in photos or reports, does not contribute as a measurement that informs the crash dynamics.
