What are the five major types of tire scuff marks?

The correct answer identifies five major types of tire scuff marks that are critical for understanding vehicle dynamics during accidents. These types include decelerating scuffs, which indicate a tire's interaction with the road surface as the vehicle slows down. Accelerating scuffs are generated when a vehicle is speeding up, highlighting moments of tire slip during acceleration. Side scuffs occur from lateral movement, showing how a tire behaves during a turn or change in direction. Combination scuffs represent a situation where the tire is experiencing multiple forces at once, such as during a turn while accelerating or decelerating. Finally, flat tire scuffs indicate that a tire has gone flat, which can significantly affect the vehicle's handling and results during an accident analysis.

Understanding these scuff marks is essential for accident reconstruction as they provide insight into the vehicle's movements leading up to a collision. These marks can help determine speed, direction, and the nature of the driver's maneuvers. Each type of scuff can be indicative of specific actions taken by the driver or the conditions present at the time of the accident.
