What tire mark results from a wheel that is locked during a collision and slides along the surface?

• A. Scuff mark
• B. Offset mark
• C. Gap mark
• D. Scrub mark

Answer: (A)

The mark produced when a wheel locks during a collision and slides along the surface is known as a scuff mark. This type of mark is created when the tread of the tire skids across the pavement, resulting in an abrasion that can indicate specific movement or direction of the vehicle at the time of the incident. Scuff marks can provide useful forensic information, such as the duration and point of contact between the tire and the surface, which can aid in accident reconstruction. They are generally characterized by a lack of distinct tread pattern and an uneven appearance, as the tire is not rolling in its normal manner when it creates these marks. In contrast, terms like "offset mark," "gap mark," or "scrub mark" refer to different types of tire impressions or conditions that are not primarily produced by a locked wheel sliding. Understanding these distinctions helps in analyzing vehicular dynamics during crashes.
