A crime, other than a Vehicle Code violation, which is associated with a traffic collision and which would normally require a report (e.g., carrying a concealed weapon), shall be contained in a separate report under a separate URN. The Traffic Collision Report and the crime report shall be cross-referenced (Refer to the Case Assignment and Reporting Volume).
