part of the vehicle resulting in injury or property damage).
OVERTURNED CRASH
A motor vehicle overturning without first striking another vehicle or an object.
SPECIAL INSTRUCTIONS
A. Print all information using a ballpoint pen with black ink.
B. In crashes involving unattended vehicles, the investigating officer will obtain ownership information
either through the mobile terminal (if available) or through Office of Emergency Management and
Communications (OEMC). If the investigating officer is not able to obtain ownership information
during his tour of duty, he will attach a note to the Traffic Crash Report stating (a) whether the
information has been requested and will be available or (b) whether this information is unavailable.
It shall be the responsibility of the supervisor approving the report to obtain the information, if at all
possible, and include it in the report.
C. Crashes involving several cars struck in sequence, or a series of events which may extend as
much as a block or occur on two different streets, shall be considered as one reportable crash.
Example: An intoxicated driver strikes several cars in succession and turns a corner striking
several more. If the crash situation has not stabilized, all successive collisions are considered part
of the original collision.
D. The printed serial number, which is located in the upper right hand corner of the crash report
immediately beneath the bar code, along with the RD Number, is used to match and combine the
sheets comprising the report file for a crash. Any unused sheets of a formset should be discarded.
E. When entering the information from the Templates into the boxes utilizing a template, a "9" or "99,"
as appropriate, should be used only when the information is not available and/or is not
applicable.
F. The officer should enter the "striking” unit as Unit 1. In most cases, the "striking" and "at-fault"
vehicle will be the same. However, it should be noted in some instances that the "striking" unit will
not be the “at-fault" unit based upon a driver's or witness's statement or physical evidence.
Example: Vehicle A disobeys a stop sign and proceeds through the intersection and is struck in the
side by Vehicle B. In this instance, Vehicle A is the "at-fault" vehicle even though it is not the
"striking" vehicle and should therefore be listed as Unit 1. It is not necessary for the "at-fault"
vehicle to strike another vehicle.
G. Enforcement action need not be taken in Type A crashes. However, if there is an apparent license
violation, mandatory insurance violation or a driver(s) is under the influence of alcohol, other drugs
or a combination thereof, or a driver(s) involved in the crash insists that the other driver(s)
committed a traffic violation and the allegation is supported by physical evidence and/or witnesses,
appropriate enforcement action will be taken.
H. For every person involved in the crash, the severity of injury must be reported.
NUMBER CODE BOXES
In boxes 1 through 30 and Contributory Cause(s), enter number codes according to the Templates.
Note: Contributory Cause Codes are located on the back of Template 1.
Whenever there are two boxes for one number marked U1 and U2, enter information for Unit 1 and Unit 2.
TYPE OF REPORT/LOCATION INFORMATION

32. For detailed explanation, see “Purpose of Report.” The entire report must be completed for both
Type A and Type B traffic crashes.
33. Self-explanatory.
34. In incidents when address is known, enter numerical street address of the incident in Box 34
marked "Address No.", e.g., "1121." Circle the appropriate direction. Enter the street name with
suffix in the next box marked “Highway or Street Name,” e.g., "State Street." For crashes at the
intersection, enter the address on the streets in which the striking or offending vehicle was
traveling. For example, 800 W. Roosevelt Rd and 1200 S. Halsted St refer to the same location.
The appropriate address to use is that of the street in which Unit 1 was traveling before the crash.
For crashes at the Intersection: "X” square before
"At Intersection With,” and enter the specific
