What type of evidence do scratches and gouges represent on a roadway?

Scratches and gouges on a roadway are primarily indicative of marks from vehicular contact with the surface. When vehicles pass over the road, their tires can leave behind these physical impressions, especially if they are heavy or if there is a rough texture or debris on the road surface. This kind of evidence can be crucial during investigations, such as those related to accidents, as it can help to determine the movement of vehicles, the weight and type of vehicles involved, and potential points of impact. The physical characteristics of these marks can provide insights into the events that transpired, making them significant for forensic analysis.
