In terms of tire marks, what do ‘scrub marks’ indicate?

Scrub marks are indicative of a tire that is rotating but also experiencing some degree of slipping. When a tire slips, it can scrub against the surface, creating visible marks that show the tire's path. This typically occurs in scenarios where brakes are applied hard, tight cornering happens, or when a vehicle accelerates sharply. The marks essentially reflect the tire losing traction and scuffing against the road surface, which is a crucial indicator for investigators in accident reconstruction.

The other options describe different conditions or characteristics that do not pertain to scrub marks. For example, rubber deposition refers to scenarios where tires are leaving residue, indicating a different interaction with the surface. The condition of tire inflation and vehicle maintenance relates more to safety and handling but does not directly connect to the pattern created by scrub marks.
