All traffic collision reports and traffic collision reports - property damage only shall be assigned a uniform reporting number (URN). The URN shall be entered on all pages of the report.
A vehicle code violation which is associated with a traffic collision and which would normally require a report (e.g., driving under the influence), shall be contained in a separate report under the same URN.
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).
