What symbol indicates the direction of travel before impact in the Field Diagram of the CR-3?

The symbol that indicates the direction of travel before impact in the Field Diagram of the CR-3 is represented by a solid line. This clear and distinct marking helps investigators visualize the movement of vehicles involved in the collision prior to the impact, allowing for a better understanding of the dynamics of the accident. The use of a solid line is visually authoritative, whereas other symbols, such as a dotted line or a cross, serve different purposes or convey different types of information in the diagram. The solid line effectively communicates the trajectory and orientation of the vehicles involved, which is crucial for accurate accident reconstruction and analysis.
