What is NOT one of the five types of physical evidence found on the roadway?

In the context of a traffic crash investigation, the five types of physical evidence found on the roadway typically include elements that directly relate to the incident's dynamics and consequences. The final resting places of vehicles and bodies, tire marks, and gouge marks are all critical indicators of the crash's impact and can help reconstruct the sequence of events.

Traffic signs, while they are important for understanding the traffic conditions and regulations at the site of the incident, do not typically qualify as direct physical evidence from the crash itself. They serve more as contextual information rather than as evidence of the physical dynamics involved in the collision. Thus, while traffic signs can take part in the overall analysis of a crash scene, they are not classified among the main types of physical evidence that emerge directly from the events leading up to and occurring during the accident.
